Total duration projectlibre5/20/2023 ![]() These tasks are relatively low work but long duration because of the low number of resources. They work alone on things like writing functional specifications. The tasks at the beginning of a development project are often done by a single person or a very small team of product and program managers. A great example of this is a software development project where tasks at the beginning of the project might be low work (few resources working alone) whereas the tasks after the midpoint of the duration might be high work (many resources working together). This difference more often comes into play in projects at the Summary task level, particularly at higher levels of summary tasks or the Project Summary, where there are lots of tasks under the summary. In a case like this, the difference between the two percentages would be huge. These two calculations will be different in situations when one person is working on a task for a time and then the project ramps up and 20 people work on it for the rest of the task. Planning time and ramping up can also change PC vs. In this example, even though half the duration is complete, there is still more than 70 percent of the work to be done due to the design of the project. So when A finishes his 5 days of work, it reads 50 percent. The duration measure of percent complete measures only how much of the duration is done. You can see A’s 20 hours in the first week and B’s 50 in the second week in Figure A. So, when the first 50 percent of the duration was complete, only 29 percent of the work was done. Seventy-one percent of the work was scheduled to be completed in the last 50 percent of the duration. The two resources evenly divided the duration of the task, but B had more than 70 percent of the work during her half of the duration. However, the percentage of work complete is only 29 percent because the schedule was “back loaded” with most of the work to be done by Resource B in the final week. When Resource A reports his four hours per day for the first five days, the percentage complete for the task is 50 percent because half of the 10-day duration is complete. ![]() It is a two-week duration task and Resource A is assigned to do 20 hours during the first five days, and Resource B is assigned to do 50 hours during the last five days. When setting up test projects to look at values or examine how MSP does something, most people set up the project so that these work to duration ratios are even, so they never see the fields in the conditions under which they can be different.Ī good example of how and when these two fields are different is a task like the one shown in Figure A. If actual work is applied with the same distribution (eight hours a day or four hours per half day, etc.), the two percents will be the same. Take, for example, a task that was five days in duration with 40 hours of work distributed as five eight-hour days. This is because the work on a task is often evenly distributed across the duration of the task, so that when half the duration of the task is complete, then half the work on the task is also complete. It is easy to dismiss these two fields as the same because, many times, their values are the same. A task with 40 hours of work and 24 hours of actual work will have a PWC of 60 percent because 24/40 =. The same is true with Percent Work Complete. If a task has a duration of three days and one and a half days have been completed (one and a half days of days actual duration), then the Percent Complete will be 50 percent because 1.5/3 =. Percent Work Complete = Actual Work/Work (PWC=AW/W). ![]() Percent Complete = Actual Duration/Duration (PC=AD/D).The two fields are calculated as follows: Percent Complete is a measure based on duration and Percent Work Complete is based on work. This article will explore the meanings of these two fields and explain why they are different and why they often appear to be the same. The deceptive thing about these two fields is that they are often the same value. ![]() Users often wonder why there are two fields if they are always the same value. One of the most common questions about MSP involves these two features. Two features that are often misunderstood can help with this tracking: Percent Complete and Percent Work Complete. From Estimated Duration and Time sheets to Personal Gantt charts and Task Delegation, there are numerous options for slicing data and tracking progress. Microsoft Project 2000 offers many ways to measure time elapsed and work completed during a project. Here is the difference between the Percent Complete and Percent Work Complete functions in MS Project and information on why these measurements matter. If a project is half over, then half the work is completed, right? Not always. Understanding Project’s Percent Complete vs.
