Question
In a Lean Software Development environment, the Project Leader strives to eliminate:
Options
- AWork in Process (WIP) and bugs.
- BDelays and building what is not needed.
- CDefects and features with low value stream values.
- DPoor requirements and changing scope.
Explanation
Lean Software Development, based on the Toyota Production System, identifies seven types of waste (muda) to eliminate. Defects and features with low value stream value are two of the core waste categories in Lean thinking. Defects cause rework and reduce quality, while features with low or no value stream contribution represent overproduction — building things nobody needs. While delays (B) and WIP (A) are also Lean concerns, they are symptoms addressed through flow optimization and pull systems, not primary elimination targets for a Project Leader. Low-value features and defects are the most direct responsibilities a Project Leader acts on.
