Technical requirements

For each phase of the business case process there are technical requirements that may be relevant to your project that will need to be considered and included in addition to general guidance and templates. Aligned to the business case philosophy, suppliers are required to meet more technical requirements as an activity progresses through the business case phases. 

Outlined below are the technical requirements for completing the implementation phase, by subject matter.

Suppliers are required to comply with these requirements except where varied within the scope of a contract. 

For further information or advice, contact the relevant team.
