Which is the best approach to optimize the workflow through the value stream?
Six months ago a service provider developed and implemented a new value stream to resolve problems that were causing incidents. Initially metrics showed that problems were being resolved quickly. However, recently there have been complaints that problems have taken too long to resolve. The organization wants to evaluate and improve the value stream. Which is the best approach to optimize the workflow through the value stream?
OPTIONS
- Use throughput metrics to identify where bottlenecks cause delays in the value stream
- Use metrics to measure work item age to identify the steps in the value stream that are causing delays
- Gather cycle time metrics to identify the steps in the value stream that use most resource
- Redesign the value stream by identifying the relevant steps, value chain activities, and practices
ANSWER
Use metrics to measure work item age to identify the steps in the value stream that are causing delays
EXPLANATION
Work item age will establish how long problems remain at each step and identify the steps that are possible bottlenecks. Work item age is a measure of the amount of time active items have been in progress. It is a leading indicator for unfinished items and highlights bottlenecks or blockers.
