Measure Then Iterate

Name what to measure, gather signal, then reprioritize - not guess and overhaul.

Key Concept

• Transformation without a number is just enthusiasm with amnesia.
• Level 1: Pick a number that shows whether something worked, watch it, then change your plan - like counting how many baskets you made before you change your shooting form.
• Level 2: Measure-then-iterate means one metric proves progress - track it, adjust, repeat, instead of enthusiasm with amnesia.
• Level 3: Transformation without a number is cheer that fades - name what success looks like, watch it, then change the method.
• Level 4: Before the next sprint, write one number you will check Friday - if it did not move, the plan changes, not the story you tell.
• Level 5: Continuous Improvement and Decision Quality both need feedback loops - unmeasured change is Failure as Feedback you never captured.
• Measure then iterate means define what would prove the change worked, watch it for one cycle, then adjust.
• Not defend the rollout because the slide was convincing.
• Failure as Feedback reads a miss; Continuous Improvement tweaks the process; Practice Small Experiments keeps trials small.
• Product lane: Lean Startup - build, measure, learn before you scale.

Examples

• We tracked checkout time for two weeks after one fewer tap - measure then iterate meant keeping the change when seconds dropped, reverting when they did not.
• I logged how many notes I actually reviewed on the jeepney for fourteen days - measure then iterate beat another app rebuild based on guilt.
