One of our managers put several (5) jobs into 1 task. and assigned 1 resource. I ask why? because the 1st job takes 5 mins. 2nd takes 15 mins, 3rd 35 mins., 5th 15 mins then back to the 1st for 10 more minutes it's completed. Then to the 2nd job finish, then 3rd job finish 4th started and finished. Complete 5th... He does not have time to fill out each job with all the jobs that go on. (mind you, he has 12 tasks with 3 to 5 jobs in those tasks.

How can I show this in project? And still be able to find the critical path

Thank you in advance R. Tuttle
