It seems with some of the commerical answer it varies.
Or can the logic that senior management would require big picture, that a milestone chart would be the answer. And if it is manager, it would be Gantt, since they would want to know a little more of the logic.
I guess if you had a question which choices, for Senior Management, if the option was Gantt or Milestone, which would you choose and why since it seems there is no different answer in PMBOK 4?
Thanks again.
