Minimum Best Effort (MBE) – the work required to achieve the most minimalistic of goals and “check the box”
Minimum Viable Product (MVP) – the work required to create something that achieves a goal of being functional and usable on the path to achieving a larger goal.
MBE is concerned with today, about creating something today, leaving it tomorrow and moving on, there is no ownership, there is no responsibility, there is no pride.
MVP is concerned with tomorrow, building something today that can continue to be built on to achieve today and maybe even tomorrow’s goals. There is ownership, pride, and responsibility in making sure that you are aligned to your end state and focussed towards getting there.
Very different meanings.
