8. Gate 5: readiness for service

Gateway Review 5: readiness for service covers the activity up to contract signature or agreement to place work with an existing supplier or partner. This review focuses on assessing:

  • whether the solution is robust before delivery
  • how ready the organisation is to implement the business changes that occur before and after delivery
  • whether there is a basis for evaluating ongoing performance.

This review takes place preferably before commissioning to take advantage of the procurement team.


  • Asset management.
  • Post occupancy evaluation.

Key actions
