The purpose of a Follow-up meeting typically is not to reprimand or dissect the performance of individuals, but rather to review the progress, evaluate the effectiveness of the solutions implemented, and discuss any ongoing issues. Therefore, while it may involve evaluating the project and its outcomes, it is not primarily about focusing on individual failures or reprimanding.
Given your options, the closest and most accurate answer would be: To conduct a final evaluation of the problem, the solution, and the implementation project.
So, the best choice would be that one, rather than "All of the above."
