Scope Creep

The uncontrolled expansion of a project's scope after work has begun, typically through new requirements, expanded features, or shifting goals. Unlike feature creep which affects the product broadly, scope creep happens within a specific initiative or sprint.

Scope creep is one of the primary causes of missed deadlines and budget overruns in software development. It happens when stakeholders add just one more thing during development, when edge cases discovered during implementation trigger expanded requirements, or when initial assumptions prove wrong and the team expands scope instead of simplifying the approach. Clear acceptance criteria, firm sprint commitments, and empowered product owners are the primary defenses.

AI development is highly prone to scope creep because model behavior in edge cases often triggers additional requirements. A team building an AI classifier discovers during development that the model struggles with a specific input category, leading to an expanded data collection effort that was not in the original scope. Growth teams can mitigate scope creep by defining minimum success criteria upfront: the AI feature must handle the top 80% of cases correctly, with graceful degradation for the remainder. Shipping the constrained version, measuring impact, and then expanding scope based on data prevents the project from growing indefinitely in pursuit of perfection.
