Running performance reviews without leaving Microsoft 365?

You've identified the core problem: if the review process isn't in the daily flow of work (Teams/Outlook), adoption tanks. The good news is you have two viable paths to run a full review cycle within the Microsoft ecosystem—one that leverages the tools you already own with some manual setup, and another that uses a purpose-built Teams app for a more automated experience.

Option 1: The DIY Path

• How it works: Use SharePoint Lists for data, Microsoft Forms or Power Apps for input, and Power Automate for reminders and workflows—all surfaced inside Teams.
• Strength: No additional licensing cost; fully uses existing M365 tools.
• Critical Trade-off: Calibration is the breaking point. At a 300-person scale, cross-team normalization requires manual Excel consolidation and meetings. Version control and bias tracking become unmanageable, which is why most orgs abandon this after 1–2 cycles.

Option 2: The Integrated Path (Teams-Native Apps)

• How it works: Apps like Teamflect or Peoplebox operate entirely within Teams, using Azure AD for hierarchy. They manage the full cycle, including 360 reviews, goal tracking, and reporting.
• Key Advantage: They solve the calibration problem specifically with built-in modules for normalization, bias flagging, and audit trails, which native M365 lacks.

Verdict
For a company of ~300 people, Option 2 is the stronger solution for long-term adoption. While Microsoft 365 provides the foundation, it does not include a native performance review system. Only Teams-integrated apps successfully solve the calibration and adoption problem at scale. The winning strategy is bringing performance management into the flow of work (Teams), not the other way around.
