The first one hides the hard parts
A single workflow can be carried by hand: one prompt, one document set, one person watching it. None of that survives contact with a second, and teams that scale by copying the first setup end up maintaining several diverging systems.
Separate the shared from the specific
Voice, escalation policy, prohibitions, and disclosure are shared and should be defined once. Scope, knowledge, and success criteria are per-workflow — each of which needs its own job description rather than an extension of the last one.
Copying the first workflow gets you to two. It doesn’t get you to five.
Expand only when corrections have flattened
Adding a second job while the first still generates daily corrections multiplies review load and disguises which system is failing. The signal to expand is a correction rate that has stopped falling, not a calendar date.
Each workflow needs its own evaluation
A shared eval set produces an average that hides a workflow performing badly. Score them separately, or a single weak area will sit undetected inside an acceptable overall number — the reason failure definitions beat accuracy targets.
Permissions multiply faster than workflows
Every new job usually needs a new data source, and each is a fresh chance to expose something. Revisit what the system is allowed to see per workflow rather than granting a superset once.
Ownership has to scale too
One person can hold one workflow in their head. At five, ownership needs to be explicit per workflow or the knowledge maintenance quietly stops and the whole set decays together.
