Often you need to have been the project manager of the previous project, or at least close enough to it to know what happened and how it went. One of the most problematic issues with analogous estimating is that itвЂ™s only as reliable as actual data the estimate is being taken from.

Then you could estimate that the Wood Work task will take 20% more time. For example, you could calculate from the plans that the log home requires 20% more timber than the previous one.

The task is for a slightly different end product.Дetermine the difference in materials and/or workmanship and figure out the difference in resources, cost, and time.

Or the foundation requires removal of rock instead of clay. For example, the slightly bigger roof trusses might require the next larger size of crane. This also sounds obvious but has equally high potential for project overruns. In this case, add in the appropriate products and services and proceed as usual.

The task needs specialty products or services that the previous one didnвЂ™t.

You have to make sure you include enough contingencies for them. This might sound obvious but itвЂ™s never the big, obvious things that cause problems for project managers, itвЂ™s the little things.

For example, the log house has slightly more square footage, or the driveway is longer, or several more windows have been added. In this case, scale the duration up or down by the appropriate amount.

The task is bigger or smaller than the last one.

Here is a checklist of potential adjustments: In fact, many project-based organizations have numerous similar projects, and this is the natural starting point. This is the best source of information because actual work completed is extremely reliable even if it needs adjustments. The four types of estimates are:ДЄs the name suggests, this is when you make an analogy to the same, or similar, task that has been performed before. Today we will expand them, work through them, and add one more. Yesterday we listed the three main types of estimates.

The resource calendar can be as simple as a listing of workersвЂ™ availability, or it can be a calendar within project management software that tracks employeesвЂ™ schedules. 30.вЂќ Obviously, the new project being planned cannot use this worker at that time (unless arrangements are made with the other project manager, I suppose). This states the availability of a resource, for example, вЂњMark is at jobsite X from Sep. To determine the availability of resources, a project manager consults a document called a resource calendar. The Inputs, Tools & Techniques, and Outputs are: The key benefit of this process is that it provides the amount of time each activity will take to complete, which is a major input into the Develop Schedule process. PMBOK, 5th Edition, Section 6.5, вЂњEstimate Activity DurationsвЂќД®stimate Activity Durations is the process of estimating the number of work periods needed to complete individual activities with estimated resources.
