Red Brick Cancer
- The Red Brick Cancer
- Process Efficiency
- Resource Effeciency
- Flow efficiency
- Customer centric
- Lean
- Both are about the same cost!
- Flow efficiency
- 1-5%
- Value Stream map
- Follow a customer through process
- 3 Laws
- Little’s Law
- Lead time = work in process / throughput
- Queuing Theory
- Law of Bottlenecks
- Can’t load system more than max capacity of bottleneck
- Law of Variation
- Arrival rate
- Work size & complexity
- Ad hoc processes
- Available capacity & competence

- Work on testing
- Classic legacy testing problem

- Improvements
- Lower amount of flow WIP will help improve system
- Like lowering water level in stream will expose the rocks
- Reduce batch size
- Improve quality
- Stop the line and root cause analysis
- Don’t swarm on work
- Lower amount of flow WIP will help improve system
- Most common red brick
- Swarm
- Used in agile
- Creates variation
- Can throw system in to resonance!!!
- Total breakdown!
- Can throw system in to resonance!!!
- Creates variation
- Should instead have a low WIP limit
- This will force people to work together!
- Used in agile
- Process Efficiency
