One of the cornerstones of Flow, Agile and the Lean Startup is quick delivery of value to customers. This reduces waste by focusing on what’s of greatest value while enabling pivoting and creating a tight bond between the organization and its customers
We call this the Minimum Business Increment (MBI). The intention is to answer the question “what is of highest value that I can deliver quickest?” MBIs lie between epics and features in size and are what calculating cost of delay (CoD) should be done on. Calculating CoD on epics infers delaying the most valuable part of an epic or the rest of it. Calculating CoD for a feature that can’t be delivered by itself is meaningless.
MBIs represent the smallest part of an initiative that can be delivered. Its value is usually known even though validation is required. By delivering in small chunks value is delivered quickly and pivoting is enabled. This is different from MVPs which are hypotheses of a viable product. They start small and build into a product. MBIs are small extensions of a product.
The MBI is one of the most critical concepts in my toolbox
