By adding the Estimated column to our Project plan and then filtering to display only the Yes values. But looking at all these rows and columns, it's difficult to tell exactly where the uncertainty lies. This has been indicated with question marks following the duration, e.g.
There are several tasks in this project plan where we are uncertain of the duration.Consider this more complex plan for a rocket launch: If a Task with no Start and/or End Dates is added to the Program's scope, the app will pick the Original Estimate value to calculate the duration and set the task's Start date to Creation date. The Estimated field in Microsoft Project is useful for seeing the holes in your project plan as it evolves. By default, the app requires two points on the timeline to generate a taskbar and determine the start and endpoints. Now that Project knows the duration, it calculates the finish date to be a week from the start date, and we finally have the basic building blocks of a non-estimated task. Just like that, the Estimated value changes from Yes to No.
OK, let’s say we're pretty sure the duration will be about a week.
Not much! Our task is still estimated, because we don't know the finish date and therefore don't know the duration either. Now, what happens when we define the start date? Because we don't really know much of anything about our task, it begins its life in Estimated status. We also see that Estimated has been filled in with the value of Yes. Duration, Start, and Finish are colored so we see we are missing data for those critical elements of a task. Immediately after hitting Enter, we see four columns colored light blue. Now, let's define a task, simply entering its name under Task Name. That will display the Estimated column, currently blank since the rest of the document is blank as well. Click the Add New Column heading and located Estimated in the field of values. Let's see it in action by starting with a new, blank project: Project allows you to see which tasks are and are not estimated by providing the Estimated (Yes/No) field. Thus it meets the definition of an estimated task. But if we only know the start date – not the finish date or duration – then we don't really have any idea of how long the task is going to take. As a general rule of thumb, when theres a conflict between two or more estimates, youd better always pick the. Move on to the next task, and go back to step 4 until all your tasks were reviewed by your team. Likewise, if we know the duration and the finish date, then we know the start date. Eventually, discuss the task durations that were chosen, and make a decision together to pick the fairest and most accurate estimate. If we know the start date and finish date, then we know the duration, via arithmetic. An estimated task is simply a task for which two or more of the following three data points are unknown: (a) start date, (b) finish date, or (c) duration. Microsoft Project allows you to represent the uncertainty of your schedule with estimated tasks.
