As Agile Coaches (and Scrum Masters), it’s your job to surface impediments blocking flow and team effectiveness, even if that leads to uncomfortable or different-than-usual conversations.
One strategy is to use your intuition, but it can be fraught with biases and wrong heuristics.
The preferred approach is to use data, evidence-based feedback, and insights from scientific research to improve team and organizational effectiveness.
Agile practitioners should focus on collecting team data, gathering multi-team data, analyzing qualitative data, and using scientific insights to drive improvement actions.
