How a Crelligent engagement works
From the ESRE Diagnostic to Architecture, Build and Evolution.
Updated 28 Oct 2026
Every Crelligent engagement follows our ESRE™ methodology, in four phases.
| Phase | What happens |
|---|---|
| Diagnostic | We assess how your business, processes, technology and data actually work today, and where the constraints are. |
| Architecture | We design the target operating system for your organisation, and the roadmap to get there. |
| Build | We implement the design: processes, systems, integrations and data, delivered in milestones. |
| Evolution | We keep your operating system healthy over time with ongoing monitoring, improvement and ESRE OS. |
Where everyone starts
Every organisation starts with an ESRE Diagnostic. Its findings determine the right path for you, whether that's Enterprise, Edge or Foundry.
One point of contact
You'll have one account lead for the whole engagement, and one contract and one invoice from Crelligent, even when specialists work on different parts of it.
