When deliverables are defined in the SOW, the project is in its infancy. After going through the Discovery phase, we have learned so much more about the unique challenges of users and stakeholders than what we knew before. Because of this, we shouldn’t be afraid to tweak deliverables if we believe one thing might be more useful than another (with, of course, permission from our client). Doing a Deliverable Gut Check internally makes sure that everyone still agrees on the deliverables originally defined given our new knowledge.
