Stage 3 of 4 · Functional & integration requirements

CTRM & ETRM requirements and design: a blueprint your vendor can deliver.

We define your future-state processes and your functional and integration requirements, then validate them against the chosen platform before the build begins.

What it is

What exactly do we need, and can the vendor deliver it?

Requirements are where most CTRM/ETRM programmes are won or lost. We work with your team to define your ideal future-state processes, document every key process the software must cover, and capture the integration requirements that connect it to the rest of your business.

We then work closely with your chosen vendor to validate fit through detailed product walk-throughs, and to refine scope, budget and timelines so they match your expectations. The result bridges the gap between your CTRM/ETRM vision and its practical implementation.

Blueprint before build: future-state processes your vendor can deliver.
Why it matters

The value to your business.

Fewer surprises during build

Clear, validated requirements reduce change requests, rework and the cost of late discoveries.

Realistic scope, budget and timeline

Deployment, training, UAT, data migration and go-live are planned and agreed with the vendor up front.

Clear ownership

Every key process has a named owner, so decisions are made quickly and accountability is clear.

Out-of-the-box first

We maximise the use of standard vendor capabilities to reduce customisation, cost and upgrade risk.
