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

How to review it in Jestor

  1. Enable log metrics on the phase field in Jestor so dwell time is captured.
  2. Review the SLA data — phases with near-zero time are candidates for removal.
  3. Look for a phase holding a disproportionate share of records; a step may be hidden inside it.
  4. Define entry criteria for each phase, so movement is unambiguous.
  5. 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.
