Planning features: must-haves first — App development for students

A feature list can grow forever, so app makers split it in two. Must-haves are the features the app cannot do its main job without — a quiz app must show a question, check the answer and show the score. Nice-to-haves, like background music or an avatar shop, can wait. Version 1 with only the must-haves is called an MVP (minimum viable product). It reaches users sooner, and their feedback shows what to build next.

Developer's tip

Must before nice — “version 1 has only what the app cannot work without”

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

Use it for: Planning any project with a deadline, from a school app to a science fair model.

Worked example: 🗒️ You are planning version 1 of a quiz app. Which feature is a MUST-HAVE? → show a question

  1. Ask: can a quiz app work without it?
  2. Without showing a question there is no quiz — so it is a must-have.

Check: Background music can wait; showing the question cannot ✓
