Process

How we work — from requirements to operations.

A clear process with defined deliverables for each step, documented using established standards.

Process

End to end — from project start to operations.

Ten steps in four phases, based on the German V-Modell XT: for each step it's clear what you get — documented using established standards.

DeliverableFunctional specification with process and data model
- BPMN 2.0
- UML activity

- C4 model
- UML component & sequence
- Security by design
Phase 3 · Build & assure
05Development
Iterative, as code and with reviews — in the target environment from day one.
DeliverableWorking increments in DEV

- AI evaluation
Phase 3 · Build & assure
07Documentation
Architecture, operations and user documentation, versioned alongside the code.
DeliverableArchitecture docs, runbooks and user guide
- arc42
- Docs as code
Phase 4 · Roll out & operate
08Acceptance
Testing with the business team against the agreed acceptance criteria.
DeliverableSigned acceptance record
- UAT
- Acceptance criteria
- Approval workflow
Phase 4 · Roll out & operate
09Go-live & rollout
