Significant pieces of engineering work can benefit greatly from design review. The review process can be as simple as an informal chat between peers or follow a formal process with a proposal document and written feedback or an in-person review session.
Design review is particularly valuable when a problem is highly constrained through user requirements or technical difficulty.
Design discussions often swing wildly between a number of proposals which all seem reasonable at first glance but are discounted due to various deficiencies with respect to requirements. Ensure the team feels empowered to challenge proposals, and not threatened by having their ideas challenged.
As a leader, prepare for your proposals to be found wanting by the team - it can hurt but if they come up with better proposals, you’re winning.
