Underlined tools link to the case study they shipped in

  1. 01 / Step

    Frame the problem

    We agree in writing on what success looks like, what constraints are real, and what we're deliberately not building.

    You end up with: A short written scope: the goal in measurable terms, the constraints we're building around, the explicit non-goals, and the one risk we're going to prove first.

  2. 02 / Step

    Prove the risky part first

    We find the assumption most likely to sink the project and test it before anyone commits engineering budget to it.

    You end up with: A working spike and a straight answer: this approach holds, or it doesn't and here's what we'd do instead — before the majority of the budget is committed.

  3. 03 / Step

    Build in the open

    Working software every week, deployed to a shared environment, so feedback happens in days.

    You end up with: Working software in an environment you control, updated weekly, with a written record of the decisions behind it.

  4. 04 / Step

    Hand over cleanly

    Tests, documentation, and a walkthrough with your team, so the system lives with you after we're done.

    You end up with: The repository, the infrastructure, the tests, the documentation, and a team that has already operated the system with us in the room.
