Hello,
I agree with your thought, but it can’t happen all the time . Mangers use several different kinds of tools to create draft schedules .These include bar charts, flow charts, and PERT charts.I will discusses in detail below. Bar charts show project stakeholders how project is progressing. A Gantt chart is one example. should show the following : 1) Task status;completed tasks are shaded out 2) Estimated project duration 3) Estimated task duration 4) Task sequence and task completed in parallel.
Flow charts helps your team closely manage and communicate project details to your supervisors and project team members. As mentioned in the this week lecture a critical path diagram is one example.Any delay in the critical path will delay completion of the entire project.
PERT(Performance evaluation and review technique) charts shows when every project task within a phase should begin , how much time is scheduled for each task, and when each task should be completed. The chart also shows all task in progress at a given time and all the dependencies between outcomes, tasks and events. No matter how experienced you are , don’t rely just on your instincts. To succeed, you need to use project management tool. Always expect the unexpected, anything can happen during a project.
