From Large Semi-Structured Docs to Actionable Data: In-Depth Evaluation Approaches Guidance
Introduction Extracting structured data from large, semi-structured documents (the detailed solution implementation overview and architecture is provided in this tech community blog: From Large Semi-Structured Docs to Actionable Data: Reusable Pipelines with ADI, AI Search & OpenAI) demands a rigorous evaluation framework. The goal is to ensure our pipeline is accurate, reliable, and scalable before we trust it with mission-critical data. This framework breaks evaluation into clear phases, from how we prepare the document, to how we find relevant parts, to how we validate the final output. It provides metrics, examples, and best practices at each step, forming a generic pattern that can be applied to various domains. Framework Overview A very structured and stepwise approach for evaluation is given below: Establish Ground Truth & Sampling: Define a robust ground truth set and sampling method to fairly evaluate all parts of the document. Preprocessing Evaluation: Verify that OCR, chunking, and any structural augmentation (like adding headers) preserve all content and context. Labelling Evaluation: Check classification of sections/chunks by content based on topic/entity and ensure irrelevant data is filtered out without losing any important context. Retrieval Evaluation: Ensure the system can retrieve the right pieces of information (using search) with high precision@k and recall@k. Extraction Accuracy Evaluation: Measure how well the final structured data matches the expected values (field accuracy, record accuracy, overall precision/recall). Continuous Improvement Loop with SME: Use findings to retrain, tweak, and improve, enabling the framework to be reused for new documents and iterations. SMEs play a huge role in such scenarios. Detailed Guidance on Evaluation Below is a step-by-step, in-depth guide to evaluating this kind of IDP (Indelligent Document Processing) pipeline, covering both the overall system and its individual components: Establish Ground Truth & Sampling Why: Any evaluation is only as good as the ground truth it’s compared against. Start by assembling a reliable “source of truth” dataset for your documents. This often means manual labelling of some documents by domain experts (e.g., a legal team annotating key clauses in a contract, or accountants verifying invoice fields). Because manual curation is expensive, be strategic in what and how we sample. Ground Truth Preparation: Identify the critical fields and sections we need to extract, and create an annotated set of documents with those values marked correct. For example, if processing financial statements, we might mark the ground truth values for Total Assets, Net Income, Key Ratios, etc. This ground truth should be the baseline to measure accuracy against. Although creating it is labour-intensive, it yields a precise benchmark for model performance. Stratified Sampling: Documents like contracts or policies have diverse sections. To evaluate thoroughly, use stratified sampling – ensure your test set covers all major content types and difficulty levels. For instance, if 15% of pages in a set of contracts are annexes or addendums, then ~15% of your evaluation pages should come from annexes, not just the main body. This prevents the evaluation from overlooking challenging or rare sections. In practice, we might partition a document by section type (clauses, tables, schedules, footnotes) and sample a proportion from each. This way, metrics reflect performance on each type of content, not just the easiest portions. Multi-Voter Agreement (Consensus): It’s often helpful to have multiple automated voters on the outputs before involving humans. For example, suppose we extracted an invoice amount; we can have: A regex/format checker/fuzzy matching voter A cross-field logic checker/embedding based matching voter An ML model confidence score/LLM as a judge vote If all signals are strong, we label that extraction as Low Risk; if they conflict, mark it High Risk for human review. By tallying such “votes”, we create tiers of confidence. Why? Because in many cases, a large portion of outputs will be obviously correct (e.g., over 80% might have unanimous high confidence), and we can safely assume those are right, focusing manual review on the remainder. This strategy effectively reduces the human workload while maintaining quality. Preprocessing Evaluation Before extracting meaning, make sure the raw text and structure are captured correctly. Any loss here breaks the whole pipeline. Key evaluation checks: OCR / Text Extraction Accuracy Character/Error Rate: Sample pages to see how many words are recognized correctly (use per-word confidence to spot issues). Layout Preservation: Ensure reading order isn’t scrambled, especially in multi-column pages or footnotes. Content Coverage: Verify every sentence from a sample page appears in the extracted text. Missing footers or sidebars count as gaps. Chunking Completeness: Combined chunks should reconstruct the full document. Word counts should match. Segment Integrity: Chunks should align to natural boundaries (paragraphs, tables). Track a metric like “95% clean boundaries.” Context Preservation: If a table or section spans chunks, mark relationships so downstream logic sees them as connected. Multi-page Table Handling Header Insertion Accuracy: Validate that continued pages get the correct header (aim for high 90% to maintain context across documents). No False Headers: Ensure new tables aren’t mistakenly treated as continuations. Track a False Continuation Rate and push it to near zero. Practical Check: Sample multi-page tables across docs to confirm consistent extraction and no missed rows. Structural Links / References Link Accuracy: Confirm references (like footnotes or section anchors) map to the right targets (e.g., 98%+ correct). Ontology / Category Coverage: If content is pre-grouped, check precision (no mis-grouping) and recall (nothing left uncategorized). Implication The goal is to ensure the pre-processed chunks are a faithful, complete, and structurally coherent representation of the original document. Metrics like content coverage, boundary cleanliness, and header accuracy help catch issues early. Fixing them here saves significant downstream debugging. Labelling Evaluation – “Did we isolate the right pieces?” Once we chunk the document, we label those chunks (with ML or rules) to map them to the right entities and throw out the noise. Think of this step as sorting useful clauses from filler. Section/Entity Labelling Accuracy Treat labelling as a multi-class or multi-label classification problem. Precision (Label Accuracy): Of the chunks we labelled as X, how many were actually X? Example: Model tags 40 chunks as “Financial Data.” If 5 are wrong, precision is 87.5. High precision avoids polluting a category (topic/entity) with junk. Recall (Coverage): Of the chunks that truly belong to category X, how many did we catch? Example: Ground truth has 50 Financial Data chunks, model finds 45. Recall is 90%. High recall prevents missing important sections. Example: A model labels paper sections as Introduction, Methods, Results, etc. It marks 100 sections as Results and 95 are correct (95% precision). It misses 5 actual Results (slightly lower recall). That’s acceptable if downstream steps can still recover some items. But low precision means the labelling logic needs tightening. Implication Low precision means wrong info contaminates the category. Low recall means missing crucial bits. Use these metrics to refine definitions or adjust the labelling logic. Don’t just report one accuracy number; precision and recall per label tell the real story. Retrieval Evaluation – “Can we find the right info when we ask?” Many document pipelines use retrieval to narrow a huge file down to the few chunks most likely to contain the answer corresponding to a topic/entity. If we need a “termination date,” we first fetch chunks about dates or termination, then extract from those. Retrieval must be sharp, or everything downstream suffers. Precision@K How many of the top K retrieved chunks are actually relevant? If we grab 5 chunks for “Key Clauses” and 4 are correct, Precision@5 is 80%. We usually set K to whatever the next stage consumes (3 or 5). High precision keeps extraction clean. Average it across queries or fields. Critical fields may demand very high Precision@K. Recall@K Did we retrieve enough of the relevant chunks? If there are 2 relevant chunks in the doc but the top 5 results include only 1, recall is 50%. Good recall means we aren’t missing mentions in other sections or appendices. Increasing K improves recall but can dilute precision. Tune both together. Ranking Quality (MRR, NDCG) If order matters, use rank-aware metrics. MRR: Measures how early the first relevant result appears. Perfect if it’s always at rank 1. NDCG@K: Rewards having the most relevant chunks at the top. Useful when relevance isn’t binary. Most pipelines can get away with Precision@K and maybe MRR. Implication Test 50 QA pairs from policy documents, retrieving 3 passages per query. Average Precision@3: 85%. Average Recall@3: 92%. MRR: 0.8. Suppose, we notice “data retention” answers appear in appendices that sometimes rank low. We increase K to 5 for that query type. Precision@3 rises to 90%, and Recall@5 hits roughly 99%. Retrieval evaluation is a sanity check. If retrieval fails, extraction recall will tank no matter how good the extractor is. Measure both so we know where the leak is. Also keep an eye on latency and cost if fancy re-rankers slow things down. Extraction Accuracy Evaluation – “Did we get the right answers?” Look at each field and measure how often we got the right value. Precision: Of the values we extracted, what percent are correct? Use exact match or a lenient version if small format shifts don’t matter. Report both when useful. Recall: Out of all ground truth values, how many did we actually extract? Per-field breakdown: Some fields will be easy (invoice numbers, dates), others messy (vendor names, free text). A simple table makes this obvious and shows where to focus improvements. Error Analysis Numbers don’t tell the whole story. Look at patterns: OCR mix-ups Bad date or amount formats Wrong chunk retrieved upstream Misread tables Find the recurring mistakes. That’s where the fixes live. Holistic Metrics If needed, compute overall precision/recall across all extracted fields. But per-field and record-level are usually what matter to stakeholders. Implication Precision protects against wrong entries. Recall protects against missing data. Choose your balance based on risk: If false positives hurt more (wrong financial numbers), favour precision. If missing items hurts more (missing red-flag clauses), favour recall. Continuous Improvement Loop with SME Continuous improvement means treating evaluation as an ongoing feedback loop rather than a one-time check. Each phase’s errors point to concrete fixes, and every fix is re-measured to ensure accuracy moves in the right direction without breaking other components. The same framework also supports A/B testing alternative methods and monitoring real production data to detect drift or new document patterns. Because the evaluation stages are modular, they generalize well across domains such as contracts, financial documents, healthcare forms, or academic papers with only domain-specific tweaks. Over time, this creates a stable, scalable and measurable path toward higher accuracy, better robustness, and easier adaptation to new document types. Conclusion Building an end-to-end evaluation framework isn’t just about measuring accuracy, it’s about creating trust in the entire pipeline. By breaking the process into clear phases, defining robust ground truth, and applying precision/recall-driven metrics at every stage, we ensure that document processing systems are reliable, scalable, and adaptable. This structured approach not only highlights where improvements are needed but also enables continuous refinement through SME feedback and iterative testing. Ultimately, such a framework transforms evaluation from a one-time exercise into a sustainable practice, paving the way for higher-quality outputs across diverse domains.From Large Semi-Structured Docs to Actionable Data: Reusable Pipelines with ADI, AI Search & OpenAI
Problem Space Large semi-structured documents such as contracts, invoices, hospital tariff/rate cards multi-page reports, and compliance records often carry essential information that is difficult to extract reliably with traditional approaches. Their layout can span several pages, the structure is rarely consistent, and related fields may appear far apart even though they must be interpreted together. This makes it hard not only to detect the right pieces of information but also to understand how those pieces relate across the document. LLM can help, but when documents are long and contain complex cross-references, they may still miss subtle dependencies or generate hallucinated information. That becomes risky in environments where small errors can cascade into incorrect decisions. At the same time, these documents don’t change frequently, while the extracted data is used repeatedly by multiple downstream systems at scale. Because of this usage pattern, a RAG-style pipeline is often not ideal in terms of cost, latency, or consistency. Instead, organizations need a way to extract data once, represent it consistently, and serve it efficiently in a structured form to a wide range of applications, many of which are not conversational AI systems. At this point, data stewardship becomes critical, because once information is extracted, it must remain accurate, governed, traceable, and consistent throughout its lifecycle. When the extracted information feed compliance checks, financial workflows, risk models, or end-user experiences, the organization must ensure that the data is not just captured correctly but also maintained with proper oversight as it moves across systems. Any extraction pipeline that cannot guarantee quality, reliability, and provenance introduces long-term operational risk. The core problem, therefore, is finding a method that handles the structural and relational complexity of large semi-structured documents, minimizes LLM hallucination risk, produces deterministic results, and supports ongoing data stewardship so that the resulting structured output stays trustworthy and usable across the enterprise. Target Use Cases The potential applications for an Intelligent Document Processing (IDP) pipeline differ across industries. Several industry-specific use cases are provided as examples to guide the audience in conceptualising and implementing solutions tailored to their unique requirements. Hospital Tariff Digitization for Tariff-Invoice Reconciliation in Health Insurance Document types: Hospital tariff/rate cards, annexures/guidelines, pre-authorization guidelines etc. Technical challenge: Charges for the same service might appear under different sections or for different hospital room types across different versions of tariff/rate cards. Table + free text mix, abbreviations, and cross-page references. Downstream usage: Reimbursement orchestration, claims adjudication Commercial Loan Underwriting in Banking Document types: Balance sheets, cash-flow statements, auditor reports, collateral documents. Technical Challenge: Ratios and covenants must be computed from fields located across pages. Contextual dependencies: “Net revenue excluding exceptional items” or footnotes that override values. Downstream usage: Loan decisioning models, covenant monitoring, credit scoring. Procurement Contract Intelligence in Manufacturing Document types: Vendor agreements, SLAs, pricing annexures. Technical Challenge: Pricing rules defined across clauses that reference each other. Penalty and escalation conditions hidden inside nested sections. Downstream usage: Automated PO creation, compliance checks. Regulatory Compliance Extraction Document types: GDPR/HIPAA compliance docs, audit reports. Technical Challenge: Requirements and exceptions buried across many sections. Extraction must be deterministic since compliance logic is strict. Downstream usage: Rule engines, audit workflows, compliance checklist. Solution Approaches Problem Statement Across industries from finance and healthcare to legal and compliance, large semi-structured documents serve as the single source of truth for critical workflows. These documents often span hundreds of pages, mixing free text, tables, and nested references. Before any automation can validate transactions, enforce compliance, or perform analytics, this information must be transformed into a structured, machine-readable format. The challenge isn’t just size; it’s complexity. Rules and exceptions are scattered, relationships span multiple sections, and formatting inconsistencies make naive parsing unreliable. Errors at this stage ripple downstream, impacting reconciliation, risk models, and decision-making. In short, the fidelity of this digitization step determines the integrity of every subsequent process. Solving this problem requires a pipeline that can handle structural diversity, preserve context, and deliver deterministic outputs at scale. Challenges There are many challenges which can arise while solving for such large complex documents. The documents can have ~200-250 pages. The documents structures and layouts can be extremely complex in nature. A document or a page may contain a mix of various layouts like tables, text blocks, figures etc. Sometimes a single table can stretch across multiple pages, but only the first page contains the table header, leaving the remaining pages without column labels. A topic on one page may be referenced from a different page, so there can be complex inter-relationship amongst different topics in the same documents which needs to be structured in a machine-readable format. The document can be semi-structured as well (some parts are structured; some parts are unstructured or free text) The downstream applications might not always be AI-assisted (it can be core analytics dashboard or existing enterprise legacy system), so the structural storage of the digitized items from the documents need to be very well thought out before moving ahead with the solution. Motivation Behind High Level Approach A larger document (number of pages ~200) needs to be divided into smaller chunks so that it becomes readable and digestible (within context length) for the LLM. To make the content/input of the LLM truly context-aware, the references must be maintained across pages (for example, table headers of long and continuous tables need to be injected to those chunks which would have the tables without the headers). If a pre-defined set of topics/entities are being covered in the documents in consideration, then topic/entity-wise information needs to be extracted for making the system truly context-aware. Different chunks can cover similar topic/entity which becomes a search problem The retrieval needs to happen for every topic/entity so that all information related to one topic/entity are in a single place and as a result the downstream applications become efficient, scalable and reliable over time. Sample Architecture and Implementation Let’s take a possible approach to demonstrate the feasibility of the following architecture, building on the motivation outlined above. The solution divides a large, semi-structured document into manageable chunks, making it easier to maintain context and references across pages. First, the document is split into logical sections. Then, OCR and layout extraction capture both text and structure, followed by structure analysis to preserve semantic relationships. Annotated chunks are labeled and grouped by entity, enabling precise extraction of items such as key-value pairs or table data. As a result, the system efficiently transforms complex documents into structured, context-rich outputs ready for downstream analytics and automation. Architecture Components The key elements of the architecture diagram include components 1-6, which are code modules. Components 7 and 8 represent databases that store data chunks and extracted items, while component 9 refers to potential downstream systems that will use the structured data obtained from extraction. Chunking: Break documents into smaller, logical sections such as pages or content blocks. Enables parallel processing and improves context handling for large files. Technology: Python-based chunking logic using pdf2image and PIL for image handling. OCR & Layout Extraction: Convert scanned images into machine-readable text while capturing layout details like bounding boxes, tables, and reading order for structural integrity. Technology: Azure Document Intelligence or Microsoft Foundry Content Understanding Prebuilt Layout model combining OCR with deep learning for text, tables, and structure extraction. Context Aware Structural Analysis: Analyse the extracted layout to identify document components such as headers, paragraphs, and tables. Preserves semantic relationships for accurate interpretation. Technology: Custom Python logic leveraging OCR output to inject missing headers, summarize layout (row/column counts, sections per page). Labelling: Assign entity-based labels to chunks according to predefined schema or SME input. Helps filter irrelevant content and focus on meaningful sections. Technology: Azure OpenAI GPT-4.1-mini with NLI-style prompts for multi-class classification. Entity-Wise Grouping: Organize chunks by entity type (e.g., invoice number, total amount) for targeted extraction. Reduces noise and improves precision in downstream tasks. Technology: Azure AI Search with Hybrid Search and Semantic Reranking for grouping relevant chunks. Item Extraction: Extract specific values such as key-value pairs, line items, or table data from grouped chunks. Converts semi-structured content into structured fields. Technology: Azure OpenAI GPT-4.1-mini with Set of Marking style prompts using layout clues (row × column, headers, OCR text). Interim Chunk Storage: Store chunk-level data including OCR text, layout metadata, labels, and embeddings. Supports traceability, semantic search, and audit requirements. Technology: Azure AI Search for chunk indexing and Azure OpenAI Embedding models for semantic retrieval. Document Store: Maintain final extracted items with metadata and bounding boxes. Enables quick retrieval, validation, and integration with enterprise systems. Technology: Azure Cosmos DB, Azure SQL DB, Azure AI Search, or Microsoft Fabric depending on downstream needs (analytics, APIs, LLM apps). Downstream Integration: Deliver structured outputs (JSON, CSV, or database records) to business applications or APIs. Facilitates automation and analytics across workflows. Technology: REST APIs, Azure Functions, or Data Pipelines integrated with enterprise systems. Algorithms Consider these key algorithms when implementing the components above: Structural Analysis – Inject headers: Detect tables page by page; compare the last row of a table on page i with the first row of a table on page i+1, if column counts match and ≥4/5 style features (Font Weight, Background Colour, Font Style, Foreground Colour, Similar Font Family) match, mark it as a continuous table (header missing) and inject the previous page’s header into the next page’s table, repeating across pages. Labelling – Prompting Guide: Run NLI checks per SOC chunk image (ground on OCR text) across N curated entity labels, return {decision ∈ {ENTAILED, CONTRADICTED, NEUTRAL}, confidence ∈ [0,1]}, and output only labels where decision = ENTAILED and confidence > 0.7. Entity-Wise Grouping – Querying Chunks per Entity & Top‑50 Handling: Construct the query from the entity text and apply hybrid search with label filters for Azure AI Search, starting with chunks where the target label is sole, then expanding to observed co‑occurrence combinations under a cap to prevent explosion. If label frequency >50, run staged queries (sole‑label → capped co‑label combos); otherwise use a single hybrid search with semantic reranking, merge results and deduplicate before scoring. Entity-Wise Grouping – Chunk to Entity relevance scoring: For each retrieved chunk, split text into spans; compute cosine similarities to the entity text and take the mean s. Boost with a gated nonlinearity b=σ(k(s-m))⋅s. where σ is sigmoid function and k,m are tunables to emphasize mid-range relevance while suppressing very low s. Min–max normalize the re-ranker score r → r_norm; compute the final score F=α*b+(1-α)*r_norm, and keep the chunk iff F≥τ. Item Extraction – Prompting Guide: Provide the chunk image as an input and ground on visual structure (tables, headers, gridlines, alignment, typography) and document structural metadata to segment and align units; reconcile ambiguities via OCR extracted text, then enumerate associations by positional mapping (header ↔ column, row ↔ cell proximity) and emit normalized objects while filtering narrative/policy text by layout and pattern cues. Deployment at Scale There are several ways to implement a document extraction pipeline, each with its own pros and cons. The best deployment model depends on scenario requirements. Below are some common approaches with their advantages and disadvantages. Host as REST API Pros: Enables straightforward creation, customization, and deployment across scalable compute services such as Azure Kubernetes Service. Cons: Processing time and memory usage scale with document size and complexity, potentially requiring multiple iterations to optimize performance. Deploy as Azure Machine Learning (ML) Pipeline Pros: Facilitates efficient time and memory management, as Azure ML supports processing large datasets at scale. Cons: The pipeline may be more challenging to develop, customize, and maintain. Deploy as Azure Databricks Job Pros: Offers robust time and memory management similar to Azure ML, with advanced features such as Data Autoloader for detecting data changes and triggering pipeline execution. Cons: The solution is highly tailored to Azure Databricks and may have limited customization options. Deploy as Microsoft Fabric Pipeline Pros: Provides capabilities comparable to Azure ML and Databricks, and features like Fabric Activator replicate Databricks Autoloader functionality. Cons: Presents similar limitations found in Azure ML and Azure Databricks approaches. Each method should be carefully evaluated to ensure alignment with technical and operational requirements. Evaluation Objective: The aim is to evaluate how accurately a document extraction pipeline extracts information by comparing its output with manually verified data. Approach: Documents are split into sections, labelled, and linked to relevant entities; then, AI tools extract key items through the outlined pipeline mentioned above. The extracted data is checked against expert-curated records using both exact and approximate matching techniques. Key Metrics: Individual Item Attribute Match: Assesses the system’s ability to identify specific item attributes using strict and flexible comparison methods. Combined Item Attribute Match: Evaluates how well multiple attributes are identified together, considering both exact and fuzzy matches. Precision Calculation: Precision for each metric reflects the proportion of correctly matched entries compared to all reference entries. Findings for a real-world scenario: Fuzzy matching of item key attributes yields high precision (over 90%), but accuracy drops for key attribute combinations (between 43% and 48%). These results come from analysis across several datasets to ensure reliability. How This Addresses the Problem Statement The sample architecture described integrates sectioning, entity linking, and attribute extraction as foundational steps. Each extracted item is then evaluated against expert-curated datasets using both strict (exact) and flexible (fuzzy) matching algorithms. This approach directly addresses the problem statement by providing measurable metrics, such as individual and combined attribute match rates and precision calculations, that quantify the system’s reliability and highlight areas for improvement. Ultimately, this methodology ensures that the pipeline’s output is systematically validated, and its strengths and limitations are clearly understood in real-world contexts. Plausible Alternative Approaches No single approach fits every use case; the best method depends on factors like document complexity, structure, sensitivity, and length as well as the downstream application types, Consider these alternative approaches for different scenarios.

By combining Azure Document Intelligence for layout-aware OCR with OpenAI models for contextual understanding, we create a well thought out in-depth pipeline that is accurate, scalable, and resilient against complexity. Chunking strategies ensure context fits within model limits, while header injection and structural analysis preserve relationships across pages to make it context-aware. Entity-based grouping and semantic retrieval transform scattered content into organized, query-ready data. Finally, rigorous evaluation with scalable ground truth strategy roadmap, using precision, recall, and fuzzy matching, closes the loop, ensuring reliability for downstream systems. This pattern delivers more than automation; it establishes a foundation for compliance, analytics, and AI-driven workflows at enterprise scale. In short, it’s a blueprint for turning chaotic document into structured intelligence, efficient, governed, and future-ready for any kind of downstream applications. End-to-End Evaluation Approaches Guidance Given the complexity of this system, it should undergo a thorough end-to-end evaluation to ensure correctness, robustness, and performance across the pipeline. Continuous monitoring and observability of these metrics will enable iterative improvements and help the system scale reliably as requirements evolve.

AI Agents are no longer just a developer’s playground. They’re becoming essential for enterprise automation, decision-making, and customer engagement. But how do you build them? Do you go workflow-first with drag-and-drop designers, code-first with SDKs, or adopt a hybrid approach that blends both worlds? In this article, I’ll walk you through the landscape of AI Agent design. We’ll look at workflow-first approaches with drag-and-drop designers, code-first approaches using SDKs, and hybrid models that combine both. The goal is to help you understand the options and choose the right path for your organization. Why AI Agents Need Orchestration Before diving into tools and approaches, let’s talk about why orchestration matters. AI Agents are not just single-purpose bots anymore. They often need to perform multi-step reasoning, interact with multiple systems, and adapt to dynamic workflows. Without orchestration, these agents can become siloed and fail to deliver real business value. Here’s what I’ve observed as the key drivers for orchestration: Complexity of Enterprise Workflows Modern business processes involve multiple applications, data sources, and decision points. AI Agents need a way to coordinate these steps seamlessly. Governance and Compliance Enterprises require control over how AI interacts with sensitive data and systems. Orchestration frameworks provide guardrails for security and compliance. Scalability and Maintainability A single agent might work fine for a proof of concept, but scaling to hundreds of workflows requires structured orchestration to avoid chaos. Integration with Existing Systems AI Agents rarely operate in isolation. They need to plug into ERP systems, CRMs, and custom apps. Orchestration ensures these integrations are reliable and repeatable. In short, orchestration is the backbone that turns AI Agents from clever prototypes into enterprise-ready solutions. Behind the Scenes I’ve always been a pro-code guy. I started my career on open-source coding in Unix and hardly touched the mouse. Then I discovered Visual Studio, and it completely changed my perspective. It showed me the power of a hybrid approach, the best of both worlds. That said, I won’t let my experience bias your ideas of what you’d like to build. This blog is about giving you the full picture so you can make the choice that works best for you. Workflow-First Approach Workflow-first platforms are more than visual designers and not just about drag-and-drop simplicity. They represent a design paradigm where orchestration logic is abstracted into declarative models rather than imperative code. These tools allow you to define agent behaviors, event triggers, and integration points visually, while the underlying engine handles state management, retries, and scaling. For architects, this means faster prototyping and governance baked into the platform. For developers, it offers extensibility through connectors and custom actions without sacrificing enterprise-grade reliability. Copilot Studio Building conversational agents becomes intuitive with a visual designer that maps prompts, actions, and connectors into structured flows. Copilot Studio makes this possible by integrating enterprise data and enabling agents to automate tasks and respond intelligently without deep coding. Building AI Agents using Copilot Studio Design conversation flows with adaptive prompts Integrate Microsoft Graph for contextual responses Add AI-driven actions using Copilot extensions Support multi-turn reasoning for complex queries Enable secure access to enterprise data sources Extend functionality through custom connectors Logic Apps Adaptive workflows and complex integrations are handled through a robust orchestration engine. Logic Apps introduces Agent Loop, allowing agents to reason iteratively, adapt workflows, and interact with multiple systems in real time. Building AI Agents using Logic Apps Implement Agent Loop for iterative reasoning Integrate Azure OpenAI for goal-driven decisions Access 1,400+ connectors for enterprise actions Support human-in-the-loop for critical approvals Enable multi-agent orchestration for complex tasks Provide observability and security for agent workflows Power Automate Multi-step workflows can be orchestrated across business applications using AI Builder models or external AI APIs. Power Automate enables agents to make decisions, process data, and trigger actions dynamically, all within a low-code environment. Building AI Agents using Power Automate Automate repetitive tasks with minimal effort Apply AI Builder for predictions and classification Call Azure OpenAI for natural language processing Integrate with hundreds of enterprise connectors Trigger workflows based on real-time events Combine flows with human approvals for compliance Azure AI Foundry Visual orchestration meets pro-code flexibility through Prompt Flow and Connected Agents, enabling multi-step reasoning flows while allowing developers to extend capabilities through SDKs. Azure AI Foundry is ideal for scenarios requiring both agility and deep customization. Building AI Agents using Azure AI Foundry Design reasoning flows visually with Prompt Flow Orchestrate multi-agent systems using Connected Agents Integrate with VS Code for advanced development Apply governance and deployment pipelines for production Use Azure OpenAI models for adaptive decision-making Monitor workflows with built-in observability tools Microsoft Agent Framework (Preview) I’ve been exploring Microsoft Agent Framework (MAF), an open-source foundation for building AI agents that can run anywhere. It integrates with Azure AI Foundry and Azure services, enabling multi-agent workflows, advanced memory services, and visual orchestration. With public preview live and GA coming soon, MAF is shaping how we deliver scalable, flexible agentic solutions. Enterprise-scale orchestration is achieved through graph-based workflows, human-in-the-loop approvals, and observability features. The Microsoft Agent Framework lays the foundation for multi-agent systems that are durable and compliant. Building AI Agents using Microsoft Agent Framework Coordinate multiple specialized agents in a graph Implement durable workflows with pause and resume Support human-in-the-loop for controlled autonomy Integrate with Azure AI Foundry for hosting and governance Enable observability through OpenTelemetry integration Provide SDK flexibility for custom orchestration patterns Visual-first platforms make building AI Agents feel less like coding marathons and more like creative design sessions. They’re perfect for those scenarios when you’d rather design than debug and still want the option to dive deeper when complexity calls. Pro-Code Approach Remember I told you how I started as a pro-code developer early in my career and later embraced a hybrid approach? I’ll try to stay neutral here as we explore the pro-code world. Pro-code frameworks offer integration with diverse ecosystems, multi-agent coordination, and fine-grained control over logic. While workflow-first and pro-code approaches both provide these capabilities, the difference lies in how they balance factors such as ease of development, ease of maintenance, time to deliver, monitoring capabilities, and other non-functional requirements. Choosing the right path often depends on which of these trade-offs matter most for your scenario. LangChain When I first explored LangChain, it felt like stepping into a developer’s playground for AI orchestration. I could stitch together prompts, tools, and APIs like building blocks, and I enjoyed the flexibility. It reminded me why pro-code approaches appeal to those who want full control over logic and integration with diverse ecosystems. Building AI Agents using LangChain Define custom chains for multi-step reasoning [it is called Lang“Chain”] Integrate external APIs and tools for dynamic actions Implement memory for context-aware conversations Support multi-agent collaboration through orchestration patterns Extend functionality with custom Python modules Deploy agents across cloud environments for scalability Semantic Kernel I’ve worked with Semantic Kernel when I needed more control over orchestration logic, and what stood out was its flexibility. It provides both .NET and Python SDKs, which makes it easy to combine natural language prompts with traditional programming logic. I found the planners and skills especially useful for breaking down goals into smaller steps, and connectors helped integrate external systems without reinventing the wheel. Building AI Agents using Semantic Kernel Create semantic functions for prompt-driven tasks Use planners for dynamic goal decomposition Integrate plugins for external system access Implement memory for persistent context across sessions Combine AI reasoning with deterministic code logic Enable observability and telemetry for enterprise monitoring Microsoft Agent Framework (Preview) Although I introduced MAF in the earlier section, its SDK-first design makes it relevant here as well for advanced orchestration and the pro-code nature… and so I’ll probably write this again in the Hybrid section. The Agent Framework is designed for developers who need full control over multi-agent orchestration. It provides a pro-code approach for defining agent behaviors, implementing advanced coordination patterns, and integrating enterprise-grade observability. Building AI Agents using Microsoft Agent Framework Define custom orchestration logic using SDK APIs Implement graph-based workflows for multi-agent coordination Extend agent capabilities with custom code modules Apply durable execution patterns with pause and resume Integrate OpenTelemetry for detailed monitoring and debugging Securely host and manage agents through Azure AI Foundry integration Hybrid Approach and decision framework I’ve always been a fan of both worlds, the flexibility of pro-code and the simplicity of workflow drag-and-drop style IDEs and GUIs. A hybrid approach is not about picking one over the other; it’s about balancing them. In practice, this to me means combining the speed and governance of workflow-first platforms with the extensibility and control of pro-code frameworks. Hybrid design shines when you need agility without sacrificing depth. For example, I can start with Copilot Studio to build a conversational agent using its visual designer. But if the scenario demands advanced logic or integration, I can call an Azure Function for custom processing, trigger a Logic Apps workflow for complex orchestration, or even invoke the Microsoft Agent Framework for multi-agent coordination. This flexibility delivers the best of both worlds, low-code for rapid development (remember RAD?) and pro-code for enterprise-grade customization with complex logic or integrations. Why go Hybrid Ø Balance speed and control: Rapid prototyping with workflow-first tools, deep customization with code. Ø Extend functionality: Call APIs, Azure Functions, or SDK-based frameworks from visual workflows. Ø Optimize for non-functional requirements: Address maintainability, monitoring, and scalability without compromising ease of development. Ø Enable interoperability: Combine connectors, plugins, and open standards for diverse ecosystems. Ø Support multi-agent orchestration: Integrate workflow-driven agents with pro-code agents for complex scenarios. The hybrid approach for building AI Agents is not just a technical choice but a design philosophy. When I need rapid prototyping or business automation, workflow-first is my choice. For multi-agent orchestration and deep customization, I go with code-first. Hybrid makes sense for regulated industries and large-scale deployments where flexibility and compliance are critical. The choice isn’t binary, it’s strategic. I’ve worked with both workflow-first tools like Copilot Studio, Power Automate, and Logic Apps, and pro-code frameworks such as LangChain, Semantic Kernel, and the Microsoft Agent Framework. Each approach has its strengths, and the decision often comes down to what matters most for your scenario. If rapid prototyping and business automation are priorities, workflow-first platforms make sense. When multi-agent orchestration, deep customization, and integration with diverse ecosystems are critical, pro-code frameworks give you the flexibility and control you need. Hybrid approaches bring both worlds together for regulated industries and large-scale deployments where governance, observability, and interoperability cannot be compromised. Understanding these trade-offs will help you create AI Agents that work so well, you’ll wonder if they’re secretly applying for your job!

Modernizing Loan Processing with Gen AI and Azure AI Foundry Agentic Service
Scenario Once a loan application is submitted, financial institutions must process a variety of supporting documents—including pay stubs, tax returns, credit reports, and bank statements—before a loan can be approved. This post-application phase is often fragmented and manual, involving data retrieval from multiple systems, document verification, eligibility calculations, packet compilation, and signing. Each step typically requires coordination between underwriters, compliance teams, and loan processors, which can stretch the processing time to several weeks. This solution automates the post-application loan processing workflow using Azure services and Generative AI agents. Intelligent agents retrieve and validate applicant data, extract and summarize document contents, calculate loan eligibility, and assemble structured, compliant loan packets ready for signing. Orchestrated using Azure AI Foundry, the system ensures traceable agent actions and responsible AI evaluations. Final loan documents and metrics are stored securely for compliance and analytics, with Power BI dashboards enabling real-time visibility for underwriters and operations teams. Architecture: Workflow Description: The loan processing architecture leverages a collection of specialized AI agents, each designed to perform a focused task within a coordinated, intelligent workflow. From initial document intake to final analytics, these agents interact seamlessly through an orchestrated system powered by Azure AI Foundry, GPT-4o, Azure Functions and the Semantic Kernel. The agents not only automate and accelerate individual stages of the process but also communicate through an A2A layer to share critical context—enabling efficient, accurate, and transparent decision-making across the pipeline. Below is a breakdown of each agent and its role in the system. It all begins at the User Interaction Layer, where a Loan Processor or Underwriter interacts with the web application. This interface is designed to be simple, intuitive, and highly responsive to human input. As soon as a request enters the system, it’s picked up by the Triage Agent, powered by GPT-4o or GPT-4o-mini. This agent acts like a smart assistant that can reason through the problem and break it down into smaller, manageable tasks. For example, if the user wants to assess a new applicant, the Triage Agent identifies steps like verifying documents, calculating eligibility, assembling the loan packet, and so on. Next, the tasks are routed to the Coordinator Agent, which acts as the brains of the operation. Powered by Azure Functions & Sematic Kernel, this agent determines the execution order, tracks dependencies, and assigns each task to the appropriate specialized agent. The very first action that the Coordinator Agent triggers is the Applicant Profile Retrieval Agent. This agent taps into Azure AI Search, querying the backend to retrieve all relevant data about the applicant — previous interactions, submitted documents, financial history, etc. This rich context sets the foundation for the steps that follow. Once the applicant profile is in place, the Coordinator Agent activates a set of specialized agents, as outlined to perform specialized tasks as per the prompt received in the interaction layer. Below is the list of specialized agents: a. Documents Verification Agent: This agent checks and verifies the authenticity and completeness of applicant-submitted documents as part of the loan process. Powered by: GPT-4o b. Applicant Eligibility Assessment Agent: It evaluates whether the applicant meets the criteria for loan eligibility based on predefined rules and document content. Powered by: GPT-4o c. Loan Calculation Agent: This agent computes loan values and terms based on the applicant’s financial data and eligibility results. Powered by: GPT-4o d. Loan Packet Assembly Agent: This agent compiles all verified data into a complete and compliant loan packet ready for submission or signing. Powered by: GPT-4o e. Loan Packet Signing Agent: It handles the digital signing process by integrating with DocuSign and ensures all necessary parties have executed the loan packet. Powered by: GPT-4o f. Analytics Agent: This agent connects with Power BI to update applicant status and visualize insights for underwriters and processors. Powered by: GPT-4o Components Here are the key components of your Loan Processing AI Agent Architecture: Azure OpenAI GPT-4o/GPT 4o mini: Advanced multimodal language model. Used to summarize, interpret, and generate insights from documents, supporting intelligent automation. Empowers agents in this architecture with contextual understanding and reasoning. Azure AI Foundry Agent Service: Agent orchestration framework. Manages the creation, deployment, and lifecycle of task-specific agents—such as classifiers, retrievers, and validators—enabling modular execution across the loan processing workflow. Semantic Kernel: Lightweight orchestration library. Facilitates in-agent coordination of functions and plugins. Supports memory, chaining of LLM prompts, and integration with external systems to enable complex, context-aware behavior in each agent. Azure Functions: Serverless compute for handling triggers such as document uploads, user actions, or decision checkpoints. Initiates agent workflows, processes events, and maintains state transitions throughout the loan processing pipeline. Azure Cosmos DB: Globally distributed NoSQL database used for agent memory and context persistence. Stores conversation history, document embeddings, applicant profile snapshots, and task progress for long running or multi-turn workflows. Agentic Content Filters: Responsible AI mechanism for real-time filtering. Evaluates and blocks sensitive or non-compliant outputs generated by agents using customizable guardrails. Agentic Evaluations: Evaluation framework for agent workflows. Continuously tests, scores, and improves agent outputs using both automatic and human-in-the-loop metrics. Power BI: Business analytics tool that visualizes loan processing stages, agent outcomes, and applicant funnel data. Enables real-time monitoring of agent performance, SLA adherence, and operational bottlenecks for decision makers. Azure ML Studio: Code-first development environment for building and training machine learning models in Python. Supports rapid iteration, experimentation, and deployment of custom models that can be invoked by agents. Security Considerations: Web App: For web applications, access control and identity management can be done using App Roles, which determine whether a user or application can sign in or request an access token for a web API. For threat detection and mitigation, Defender for App Service leverages the scale of the cloud to identify attacks targeting apps hosted on Azure App Service. Azure AI Foundry: Azure AI Foundry supports robust identity management using Azure Role-Based Access Control (RBAC) to assign roles within Microsoft Entra ID, and it supports Managed Identities for secure resource access. Conditional Access policies allow organizations to enforce access based on location, device, and risk level. For network security, Azure AI Foundry supports Private Link, Managed Network Isolation, and Network Security Groups (NSGs) to restrict resource access. Data is encrypted in transit and at rest using Microsoft-managed keys or optional Customer-Managed Keys (CMKs). Azure Policy enables auditing and enforcing configurations for all resources deployed in the environment. Additionally, Microsoft Entra Agent ID, which extends identity management and access capabilities to AI agents. Now, AI agents created within Microsoft Copilot Studio and Azure AI Foundry are automatically assigned identities in a Microsoft Entra directory centralizing agent and user management in one solution. AI Security Posture Management can be used to assess the security posture of AI workloads. Purview APIs enable Azure AI Foundry and developers to integrate data security and compliance controls into custom AI apps and agents. This includes enforcing policies based on how users interact with sensitive information in AI applications. Purview Sensitive Information Types can be used to detect sensitive data in user prompts and responses when interacting with AI applications. Cosmos DB: Azure Cosmos DB enhances network security by supporting access restrictions via Virtual Network (VNet) integration and secure access through Private Link. Data protection is reinforced by integration with Microsoft Purview, which helps classify and label sensitive data, and Defender for Cosmos DB to detect threats and exfiltration attempts. Cosmos DB ensures all data is encrypted in transit using TLS 1.2+ (mandatory) and at rest using Microsoft-managed or customer-managed keys (CMKs). Power BI: Power BI leverages Microsoft Entra ID for secure identity and access management. In Power BI embedded applications, using Credential Scanner is recommended to detect hardcoded secrets and migrate them to secure storage like Azure Key Vault. All data is encrypted both at rest and during processing, with an option for organizations to use their own Customer-Managed Keys (CMKs). Power BI also integrates with Microsoft Purview sensitivity labels to manage and protect sensitive business data throughout the analytics lifecycle.
