This is the same situation that existed when we discussed the use of the milestone statusing method to status tasks. The percent complete for summary-level WBS elements (control packages) has not yet been defined. It is simple, however, to extend the concept of percent complete to a control package by using the concept of weighted percent complete that has already been defined for work packages. Its formula for application at a control package level is given by: Page 80 and where the summation is taken over all work packages contained in the given WBS element (control package) in the hierarchical ordering. Usually, the same status method cannot be used on all work packages. However, it is desirable that the majority of work packages on a project be statused the same way in order to promote a uniform philosophy of work (progress) measurement on the project. It is our belief that the majority of work packages on a project should be statused using the quantity method. Modern Project can be used to support all of the statusing methods mentioned above. Let us see how this works. First, assume that a work package will be statused using the quantity statusing method. The Progress Transactions Entry/Edit tool (shown in Figure 3-5) gives the user three choices for entering statusing information for tasks. The most common method for entering progress information for this statusing method is to enter the number of units completed for a task in the Qty to date field. The Modern Project system converts this number into a Figure 3-5. Progress Transactions Entry/Edit Tool. Page 81 percent complete for the task by dividing it by the task's quantity budget. If, instead, the Qty to date field is left blank and a number is entered into the Qty this period field, then Modern Project calculates the percent complete for the task a little differently. It first divides the number entered in the Qty this period field by the task's quantity budget. This determines the contribution to the percent complete achieved during this period. Next, it adds this contribution to the percent complete figure already in the database to get the percent complete for the task. The third possibility is for the user to override the quantity method by entering a percent complete figure directly into the database for the task. In this case, Modern Project works backward to compute the number of units completed to produce the percent complete figure entered. It stores this number in the database, together with the percent complete figure entered. This third way of entering statusing information defeats the quantity statusing method for a task, but it is necessary in certain situations, as is explained later. If no progress has been made on a given task, then the quantity (completed) for the task should be zero. Next, assume that a work package will be statused using the milestone method or the indirect statusing method. In either case, we already know the percent complete for the work package in advance. In the milestone method case, i...
