Summary:
- Lower WIP (work in progress) means less variability in the delivery timeline. All tasks have some variability and more tasks = a greater sum of variability.
- The optimal batch size depends on the costs of not delivering the work (delayed features to customers, not knowing you built the wrong thing until later, etc) versus the cost of delivering it (how much effort it is to get signoff & deploy the changes).
- A lot of my work is about reducing the delivery cost to near zero, so if you see costs here, point them out and I’ll help remove/reduce them.
- If you have a giant backlog that’s all committed, then getting to your recent great idea is going to take a long time (high queue length)
