Implement an MVP in 3 weeks. But which features are really minimal?

From an idea to a minimum that works

TMFlota is a car reservation system for the Gypsy Group, a brand that wanted to give customers simple, real-time access to its fleet. The challenge? To build a full MVP in 3 weeks – from workshop to finished product. The key question was: what really needs to be ready for launch, and what can wait?On the priority list were the booking process, user profile, offer review and integration with an external CRM system. Features such as real-time rental monitoring and multilingualism, important but not essential for a startup, receded into the background.

How does fast-track work look like?

Such a mode is not a sprint. It’s a marathon at the pace of a sprint. Fast-track requires a different dynamic than a classic implementation, everything happens in parallel, not in sequence. The UX team designs the next modules, while the developers implement the ones already approved. There is no room for „we wait for them to finish.” For this to work, you need clear rules, fast communication and real availability of decision makers. In projects with a short time window, efficiency comes from a clear communication structure. Identifying who is responsible for decisions on the client side and the implementation team avoids delays and maintains consistency.It is this element that often determines whether a project completed in three weeks is successful or stretched by the need for additional iterations.

Speed versus quality – how do you find the balance?

The biggest challenge was not time, but the trade-off between ideal and possible.The UX team had to develop a shared vision with the client, good enough to work right away, but flexible enough to be developed later. Not every decision was obvious.Some elements, like the booking logic and the order of steps in the process, required testing and consultation after implementation. This is natural. Fast-track is not about perfection. It’s about bringing the product to life as quickly as possible and allowing the team to observe how users react in a real-world environment.

What did we get out of this project?

The most important conclusion?Asynchronous work between UX and the development team is possible as long as everything is well prepared at the input. Well-described requirements, decisions written down at the outset and a clear hierarchy of responsibility avoid chaos, even at maximum speed. MVP in 3 weeks is not the art of code. It’s the art of trust, communication and having the courage to say „we’ll do this now, the rest can wait.”

Why CrocoCode?

Technology only matters if it has a business effect. We know how to plan the process so that it works not only at the implementation stage, but also after the release. We know which decisions are crucial and which can evolve with the product. And we always choose what really drives the business, not what looks nice in the backlog.
