A project manager is creating a project plan and has identified all of the tasks (as well as predecessors) on the WBS. The only thing she has left to do is identify the task durations. She is concerned that weather over the life of the project (let's say 4 weeks) is expected to be worse than normal for that time of the year and weather severely impacts work on the project. Which of the following times would likely be a better approach to duration selection given her concerns? Optimistic time Likely time Pessimistic time The approach to the duration selection will not impact the project expected completion time
