Minimal product

As explained in Functional Design and Architecture: Examples in Haskell

A minimum viable product is a usable product version with sufficient functionality to validate the product idea and support further development.

A minimum viable product (MVP) is a usable sample program with limited but sufficient functionality to verify a product idea. It creates something real early, supports fast feedback, and provides a foundation for continued development rather than serving as a disposable prototype. section 3.1.1 section 3.4

A practical MVP:

  • Passes through enough application components to demonstrate that the subsystems can work together. section 3.1.1
  • Uses limited functionality to verify the product idea without implementing every requirement. section 3.1.1
  • Keeps architecture, component design, and interfaces in view because later development builds on the initial code. section 3.1.1 section 3.4
  • Works with integration tests to establish a fast feedback loop and verify behavior in a real environment. section 3.4

Spaceship control simulator

Andromeda Control Software begins as a draft spaceship-control application paired with a simulator. Engineers can use the limited system to test spaceship systems and explore reliability before launch, while hard real-time behavior and minimal latency remain outside the MVP’s scope. section 3.0 section 3.1.1

How Functional Design and Architecture: Examples in Haskell covers it

How deep it goes
Explains purpose, workflow, integration, architecture, and scope boundaries, but stops short of detailed implementation requirements.
Examples
Demonstrates a spaceship-control draft paired with a simulator for reliability testing before launch.
What you can do after
Build an early integrated application that verifies an idea and supports further architectural development.
How it connects
Connects MVPs with integration tests, software architecture, interfaces, simulators, and fast feedback loops.
