What this means in practice
Stretch moves sit between safe adjacency and full reinvention. The target is reachable — the training time fits the runway or the skill overlap is meaningful — but the worker should prove the new skills with a project or course before betting on it.
A Bookkeeping Clerk moving toward an Internal Controls Associate role is a stretch move: the accounting context transfers, but audit and controls thinking need demonstration. The calculator flags these so ambition does not get mistaken for a plan.
