5. Reduce WIP
• more WIP increases lead time
• longer lead times = worse quality
• Quality and WIP are strongly connected, they
should be implemented at the same time
6. Deliver frequently
• frequent small gestures are better than
infrequent large gestures
• small scale actions usually only entail small
costs
• builds trust with upstream partners/customers
7. Balance demand and
throughput
• The point is
• shows bottlenecks
• allowes to give the employees a free hand - Kaizen
cultur
• How?
• pull system regulates throughput
• political capital can be used to manage demand
8. Prioritize
• Reason
• increases delivered business value
• How?
• requires trust from upstream partners/customers
• requires high predictability
• focus on business value, not amount of code
9. Increase predictability
• Motive:
• high variability leads to more WIP and longer lead times
• high variability correlates negatively with predictability
• How?
• requires a mature organization
• wise workers - agree and change their behavior
10. Conclusion
• WIP correlates with quality
• frequent deliveries and consistent high quality build trust
• pull system regulates demand and throughput
• good prioritization maximizes delivered business value
• confidence creates opportunities for improvement
