Below is how it works:

 

• Per-subscription scoring: Each subscription receives a score across the five pillars (Cost, Security, Reliability, Operational Excellence, Performance). These are based on how many recommendations are implemented versus outstanding.

• Aggregate scoring: When you select multiple subscriptions, Advisor does not average the scores. Instead, it weights the aggregate score by resource impact meaning the calculation considers the relative importance and optimization state of resources across all selected subscriptions. Larger workloads or subscriptions with more resources carry more weight in the combined score.

• Dynamic recalculation: The scoring logic was updated to provide more accurate results. This means the aggregate score reflects optimization progress across all resources, not just a simple mean of subscription-level scores.
