About this routine

When software projects risk missing deadlines due to unexpected complexity, Ryan Singer scope hammering offers a systematic way to cut non-essential work. Built as part of the Shape Up methodology created at Basecamp, this practice treats time as a fixed boundary rather than an elastic variable.

Instead of extending deadlines or working overtime, scope hammering forces you to question every task left on the board. You separate the essential core of a feature from extra polish, edge-case handling, and secondary enhancements. By hammering away everything that is not required for a working product, you guarantee on-time shipping.

This 40 minute session helps project leads and developers pause mid-cycle, map remaining work into clear scopes, and make explicit trade-offs. You end the session with a reduced backlog and a clear path to complete the project on schedule.

Why this routine works

Protects hard shipping deadlines without forcing team burnout
Differentiates essential core features from optional polish
Reduces mid-cycle decision fatigue by forcing explicit scope trade-offs
