- Look at the end-to-end flow, not individual steps.
- Common set: flow velocity, flow time, flow efficiency, flow load, flow distribution.
- Connects delivery to business results.
The flow metrics
| Metric | Measures |
|---|---|
| Flow velocity | Items completed per period |
| Flow time | Time from start to done |
| Flow efficiency | Active time vs waiting time |
| Flow load | Work in progress |
| Flow distribution | Mix of features, defects, risk and debt work |
These come from Mik Kersten's Flow Framework, described in Project to Product (2018).
Team vs value stream
A single team can look fast while the whole value stream is slow because of handoffs and approvals elsewhere. Value stream metrics show the full journey.
Getting started
- Map the stream with value stream mapping
- Pick two or three metrics you can collect now
- Review them with everyone in the stream, monthly
Myth vs reality
Myth · Value stream metrics replace team metrics.
Reality · They add the end-to-end view.
Myth · You need special tools.
Reality · Start with data from existing tools.
Myth · More work in progress means more output.
Reality · It usually means longer flow time.
