Scope Creep
Incremental expansion of project scope without corresponding expansion of timeline, budget, or staffing — typically caused by weak change-control, not by individual bad-actor requests.
Full definition
Scope creep is the incremental addition of work to a project after scope has been set, without corresponding changes to timeline, budget, or staffing. It is rarely caused by malicious clients; it is almost always caused by weak operational defenses — no change log, no structured scope-change conversation, no pricing model for additions, and a culture where 'just one more thing' is absorbed rather than priced. At agencies, scope creep compounds: the first unchallenged addition normalizes the second; the second normalizes the third. Recovering margin on a scope-crept project usually requires either client renegotiation (friction) or absorbing the cost (margin).
When this matters
Scope creep becomes destructive when project margins fall below 25% gross. At that level, two unchallenged additions can flip a project from profitable to loss-making. Healthy agencies have explicit, rehearsed scope-change conversations.
Commonly confused with
Scope creep is often treated as a client problem. It is almost always an operating problem: the agency permitted it because no defensive protocol existed.
