For buyers contracting authority
Choose 72223000 when the deliverable is a defined picture of what the organisation needs: a requirements specification, a technical-options study, or a functional review that a later build will be measured against. The accepted output is the document and the recommendation, not working software.
The boundary that trips contracting authorities is the line between this code and its two closest siblings. Business analysis consultancy (72221000) examines processes and the business case; requirements review (72223000) translates that into the IT requirements a system must meet. Strategic review and planning (72222000) sets direction across a portfolio, while 72223000 scopes a specific need.
A second trap is the testing siblings. Quality assurance assessment (72225000) and acceptance testing consultancy (72226000) review a system that has been built; requirements review happens before the build exists. Where a single contract folds requirements work into a larger delivery, set the primary CPV code by the dominant deliverable, not by the whole bundle.
