The reference you are making is in paragraph 5.56. We're talking about the importance of the health of a project being reported to the people who have oversight of those projects so they understand where the project is.
This is an example in the business-to-business project where it was confusing to understand exactly what stage the project was at because they seemed to have said it was closed, but then they were also continuing to work on it.
Understanding that is important. Going through projects and making sure that each stage is met along the way is critically important to understand that all the requirements as well as the time and the budget are on schedule, to make sure the project is going to deliver what was intended.
We would never ask a department to go back and try to redo gates that have already been passed. But we would expect the department, at the point they were putting in place a new framework, to at least look at those projects that were in place and identify if they seem to be on the right path to deliver what they were intended to deliver, regardless of the fact that you can't go back and re-document certain gates, whether they were passed or not passed.
