How Many Phases Should a Process Have?
Deciding how many phases a process should have comes down to one test: does the phase change who is responsible or what happens next? If neither, it is a field value rather than a phase.
What too many phases costs
Each column adds a place for work to sit and a decision about when to move it.
- Cards moved in batches because nobody moves them individually
- Phases with near-zero dwell time, passed through mechanically
- Disagreement about when something counts as moved
- A board too wide to read on one screen
Signs you have the wrong number
| Symptom | Likely cause |
|---|---|
| Near-zero dwell time | The phase is not a real step |
| One phase holding everything | A step is hidden inside it |
| Cards moved in batches | Movement is administrative, not operational |
| Arguments about status | Entry criteria are undefined |
How to review it in Jestor
- Enable log metrics on the phase field in Jestor so dwell time is captured.
- Review the SLA data — phases with near-zero time are candidates for removal.
- Look for a phase holding a disproportionate share of records; a step may be hidden inside it.
- Define entry criteria for each phase, so movement is unambiguous.
- Change the phases in a draft version and publish once agreed.
Why choose Jestor for process design?
Jestor records dwell time per phase, which turns the question of how many phases you need from a design debate into an observation.
Because phases are configured visually and changes can be tested in a draft version, adjusting a live board is a normal activity rather than a risk.
Frequently Asked Questions
When is a phase unnecessary?
When it changes neither responsibility nor what happens next. See jestor.com.
How do I spot a hidden step?
A phase holding a disproportionate share of records usually contains one.
Can I change phases on a live board?
Yes, safely, using a draft version.
