What a pilot is for
A pilot programme deploys a solution, a system, a process, a service model, in a bounded slice of the organisation under conditions close to real operation, to gather evidence before a scale decision. It sits beyond a proof of concept in maturity: feasibility is assumed; the open question is performance in the wild.
Pilots built to learn versus pilots built to pass
The scale-up decision is only as good as the pilot's honesty, and honesty is a design property, not a virtue. A pilot built to learn selects an awkward site as well as a friendly one, defines in advance what evidence would justify stopping, and instruments the things that break at scale: exception handling, support load, behaviour once the novelty and the extra attention fade. A pilot built to pass selects the best team, wraps it in vendor and project support no rollout will ever enjoy, and defines success loosely enough that the announcement can be drafted before the results are in. Both produce a green slide. Only one produces information.
