Kamal Hinduja : How to measure the effectiveness of a Scrum Master?

When the team succeeds you succeed, and when the team fails you fail. That's it.

The complication is that the Scrum Master is not a hierarchical manager, i.e., does not control the team, but is more a coach/mentor of the self-managing team. Still the Scrum Master effectiveness can be linked to the team effectiveness. Some ideas for communicating team effectiveness include focusing on value, quality, and flow:

• Cumulative Flow Diagram (CFD): Visualises flow stability and identifies bottlenecks of items.
• Cycle Time / Lead Time: Measures how long it takes for work to move from “in progress” to “done.”
• Escaped Defects: The number of defects found in production, a quality indicator.
• Rework Rate: Frequency of stories reopened or changed after completion.
• Stakeholder Satisfaction: Qualitative feedback on perceived value and responsiveness.
• Team Health Metrics: Team engagement, morale, psychological safety, and adoption of Agile principles.
• Predictability: How consistently the team meets its Sprint goals or delivery forecasts.

A short answer might be: A Scrum Master is effective when the team delivers value predictably, communicates transparently, and continuously improves — without depending on the Scrum Master to enforce Scrum.
