A sprint is one workflow either way. The spread is complexity, not padding. These six factors account for nearly all of it.
Number of systems integrated
One well-documented API sits at the bottom of the band. A CRM, a ticketing system, a data warehouse, and a legacy ERP with no sandbox sit at the top.
Data readiness
Clean, permissioned, retrievable content is cheap. Scattered documents with no access model, no ground truth, and no owner means we build that first.
Regulated or customer-facing surface
Internal drafting tools carry less burden than anything touching customers, money, health, or legal — those need tighter controls and heavier review.
Eval depth required
A representative eval set with a handful of dimensions is one cost. Adversarial cases, per-release regression gates, and human-rated judgment sets are another.
Approval gates and reviewers
Each human gate is a workflow of its own: queues, routing, escalation, SLAs, and an audit trail that survives inspection. More reviewers, more surface.
Change-management load
Five power users who want the tool costs little. Two hundred people across three time zones who did not ask for it means training, rollout, and support design.
We price the band at the end of scoping, not before it — and the number in the scope document is the number on the invoice. Significant scope changes are handled through change orders that adjust timeline, budget, or both.
