Plenty of projects die trying to be born complete. The founder gathers everything they ever wanted into one list, the project becomes large and slow and expensive, and it launches months later to discover that what was built is not what people wanted.
What the shorthand really means
MVP means minimum viable product, and the important word is viable, not minimum. It is not a reduced or shoddy version; it is a version that does one thing well enough that people actually use it, and pay for it if it is paid.
How to sort features
Write everything you want, then ask one question of each item: can the customer achieve their main purpose without it? If yes, it is not in version one. That question alone halves most lists.
- Delivery app: ordering, payment and tracking are core. Loyalty points are not.
- Learning platform: watching a lesson and tracking progress are core. Certificates and forums wait.
- Store: browsing and buying are core. Smart recommendations wait.
Why it genuinely saves money
The saving is not only in building less, it is in not building the wrong thing. Any feature built before the need is confirmed may be thrown away entirely, along with its time, cost and maintenance. A small first version gives you real users who tell you what is worth building, so the rest of the budget is aimed by knowledge rather than guesswork.
When this approach does not fit
It does not fit when what is missing is dangerous: a system handling payments or sensitive data cannot ship with partial security. And it does not fit when the single feature is the whole product, leaving nothing to trim. In both cases the principle holds in a modified form: build the smallest scope that works safely, not simply the smallest scope that works.
In short
Ask yourself the smallest thing you could launch that one real person would use next week. Build that first. The rest gets clearer once you watch people use it.
