App Dev Worksheet: Planning Features

App development lesson 6: Planning features: must-haves first · Set 617 · 40 questions

Developer's tip (Must before nice): Must-have: the app cannot do its main job without it. Nice-to-have: it can wait. Version 1 (the MVP) = must-haves only. Days left for extras = days available − days for the must-haves.
