To answer this question, you must first realize that this is not necessarily a bad situation. Many projects have repeated work. Therefore, choice ‘See what can be done to make sure the work is carefully reworded to remove the similarity’ is eliminated. There could be some benefit to having the same resource do all the work packages, however, this may not be practical. The question asks for what MUST the project manager do, and they do not need to do choice ‘Make sure the same resource completes all the similar work packages’. There is no benefit to scheduling the work packages close to each other so ‘Make sure the first and last of these work packages is scheduled close in time to each other’ cannot be correct. Choice ‘Plan in continuous improvement activities’ provides the knowledge gained from the earlier work packages to be used by the later work packages, making the later ones faster and easier. Therefore ‘Plan in continuous improvement activities’ is the best answer.
