- 13. What’s most important, right now? IMPACT DRIVEN DEVELOPMENT - STEP 1 @richardw1001 | nhance.today
- 14. What’s most important, right now? IMPACT DRIVEN DEVELOPMENT - STEP 1 ● Who are your customers? What matters most to them? ● What are the current business objectives? Why? ● What are the weakest things about your product right now? Example: getting more customers, keeping customers, saving time @richardw1001 | nhance.today
- 15. What’s most important, right now? IMPACT DRIVEN DEVELOPMENT - STEP 1 ● When you improve the weakest thing enough, it will stop being the priority ● You’ll need to re-assess as you go along ● You’ll need a planning process that lets you steer as you go @richardw1001 | nhance.today

- 17. What does better look like? IMPACT DRIVEN DEVELOPMENT - STEP 2 ● What are you hoping to see? Why? ● There’s always room for improvement - “done” is misleading as a concept ● How much better is “good enough - for now”? @richardw1001 | nhance.today
- 18. What does better look like? IMPACT DRIVEN DEVELOPMENT - STEP 2 ● What could you measure to see improvements? ● How can you measure these easily? ● What are their current scores? Examples: user feedback, analytics, performance metrics, survey scores... @richardw1001 | nhance.today
- 19. Where’s the leverage? IMPACT DRIVEN DEVELOPMENT - STEP 3 @richardw1001 | nhance.today
- 20. Where’s the leverage? IMPACT DRIVEN DEVELOPMENT - STEP 3 ● Pareto principle - “20% (or less) of inputs lead to 80% (or more) of outputs ● Which parts add the most value? How can you focus on these? ● Which parts take the most effort? How can you reduce or eliminate these? How: break down metrics, simplify design, filter designs for cost/value ratio @richardw1001 | nhance.today

- 22. How can we deliver an outcome sooner? IMPACT DRIVEN DEVELOPMENT - STEP 4 ● Measure and optimise for cycle time ● That is mainly driven by: ○ Architecture/technical strategy ○ Team autonomy ○ Delivery/release strategy ● Focus on purpose, eliminate waste @richardw1001 | nhance.today
- 23. How can we deliver an outcome sooner? IMPACT DRIVEN DEVELOPMENT - STEP 4 ● Good quality strategy, so you can release confidently at speed ● Design for releasability - feature toggles, rollout model, canary releases, etc ● Collaborate - eliminate hand-offs and build as a team @richardw1001 | nhance.today

Editor's Notes
- Building software is expensive Businesses build for impact! Competitive advantage Developers build to be proud of impact
- Title of scrum book Well-intentioned, but misinterpreted Can lead to nightmare of dark agile - weaponised against the team Is the wrong question
- Better version - doesn’t matter how much work you do, matters what impact it has
- The main focus traditionally - assembly lines, industrial revolution, Taylorism,
- What really matters - what’s the real objective - what does the stuff you did lead to?
- 7th principle in agile manifesto Depends how you define working
- Definition of done Piling up unreleased work, batches Linear flow No feedback loop
- Means released, and getting good results Might need iteration to achieve this
