Policy : Enable Evidence-Based Leadership

Commitment to Decisions Grounded in Reality The most damaging decisions in organisations are often made confidently, on the basis of untested assumptions, outdated mental models, or whoever spoke last in the room. Evidence-based leadership is a commitment to seeking out the best available information before deciding, updating beliefs when evidence changes, and creating cultures where data and challenge are welcomed rather than resisted.

What This Means Evidence-based leadership does not mean paralysis by analysis or the elimination of judgment. It means that judgment is applied to evidence, not as a substitute for it. It means senior leaders are willing to be wrong, to be shown better data, and to change direction when the evidence demands it. It also means creating the systems and habits that make evidence accessible and actionable.

Our approach to enabling evidence-based leadership includes:

• Measurement as a Practice – We invest in measuring what matters: DORA metrics, flow metrics, team engagement, customer outcomes, and quality indicators. What gets measured can be improved.
• Data-Informed Retrospectives – Decision reviews and retrospectives use evidence, not just memory. We ask "what did the data show?" alongside "what did we feel went well?"
• Challenging Assumptions Explicitly – Leaders create space to surface and test assumptions before committing to a direction. "What are we assuming here?" is a question that belongs in every planning conversation.
• Research and External Perspective – We draw on research (DORA, BVSSH, academic studies) and external benchmarks to challenge internal norms and expand what we think is possible.
• Psychological Safety for Data-Driven Dissent – People must feel safe to bring evidence that contradicts the prevailing view. Shooting the messenger is incompatible with evidence-based culture.

Why This Matters Decisions made on incomplete or incorrect information produce worse outcomes — regardless of how confident or senior the decision-maker is. Evidence-based leadership builds trust (people can see the reasoning), improves quality (better inputs, better outputs), and creates learning cultures that improve continuously.

Our Expectation Leaders articulate the evidence basis for significant decisions and invite challenge. They invest in building measurement capability in their teams and use data actively in planning and retrospective conversations. They model intellectual humility: being willing to say "the evidence suggests I was wrong" is a strength, not a weakness.
