MVP (minimum viable product) is the smallest version of an app or system that already solves the user's main problem, without the extra features that just delay launch. Eric Ries popularized the term in The Lean Startup as a way to validate an idea with minimal time and money before investing in expanding it.
The same logic applies to an internal business system: instead of spending months planning a "perfect" system with every conceivable feature, a company builds the core first - order, client or task tracking - which the team starts using right away, then expands based on actual need rather than upfront guesswork.
No-code platforms directly support this approach: the MVP of an internal system can be built in an afternoon and kept evolving on the fly, without needing a new development cycle for every change.
