Four stages, and none of them ends.
Most engagements are a relay: strategy hands a deck to delivery, delivery hands a system to whoever is left. Ours is a loop. The people who reasoned about the constraint stay accountable for the build, and the build keeps reporting on whether the reasoning held.
What you keep at the end of each stage is written down before the stage starts. If we cannot say what you will be holding, we have not scoped it properly yet.
Evidence stays close to the decision.
Every move starts with a real input and stays attached to the operating context where the decision has to work. Three worked examples, each with its framing attached.
What stays connected.
Evidence becomes a decision. A senior builder turns it into a working system. The outcome feeds the next call. Five things hold that loop together, and every one of them has a name against it.
The loop only holds if someone owns each turn of it
No handover to an account manager, no ticket queue between the thinking and the building. The owner approves direction and owns the outcome; we own whether the system deserves to still be running in a year.
Bring the operating reality. We will find the constraint.
We will help you test the commercial reason to move and define exactly what you should keep, whether or not the answer is something we build.
