Activity list – why is that?

3 min.

Summary

After work package planning has been completed, the activity list is created as a table. It is the following method to be applied according to the work breakdown structure. The activity list is the link between the work breakdown structure and the schedule.
The real added value is the task list, as a means of reducing the project duration, in that the core team with its expertise and the project manager identifies as many logical sequences as possible that can contribute to reducing the project duration. Even in an agile environment, dependencies need to be identified and taken into account. Splitting user stories without creating additional dependencies is an important skill of the SCRUM team.

What is the task list?

After completion of the work package planning, the process list is created. It is a table of all work packages and contains essential information from the work package planning from which the scheduling is derived in the further course.

The work breakdown structure (WBS) does not yet have any information on the functional sequence (“technical” dependencies). The activity list helps here. In project management, it is a “bridge medium” between WBS and the schedule. The activity list is a table of activities in the project. Based on the activity list, the project manager can determine the start and end dates of the work packages.

What is the added value of the activity list?

After creating the task list, it can be estimated for the first time whether it is possible to achieve the project goal within the framework of the available resources. Now it is possible to add all costs and capacities that were considered necessary by the WP managers. However, it is not yet possible to draw conclusions about the sufficient availability of the necessary capacities, since normally there is no uniform utilization, but rather individual capacity peaks represent the problem. It is also possible to record which predecessors are necessary to start a work package.

The real added value is the task list, as a means of reducing the project duration, in which the core team with its expertise and the project manager identifies as many logical sequences as possible that can contribute to reducing the project duration. So a lazy use of the end-start sequence, because this is so convenient and easy to do, would cost the client project time and drive up project costs. Alternative sequences such as Beginning-Start help the project manager reduce the number of tasks on the critical path. This simplifies project control. The work package managers should not define the inputs for the sequence relationship in a quiet chamber, but communicate them to the core team (sub-project manager or project manager in the program), which then determines optimized sequences. The creation and discussion of the process list thus raises the potential for later optimization of the flow and schedule at an early stage.

Differentiation / forerunner to the schedule

From the sequence of the work packages it can be derived when which work package starts. Work packages that do not have a direct predecessor can start immediately. All others follow. An initial schedule can be derived from this. This, however, is not much more than an indication, since diverse framework conditions such as staff vacation, capacity limits of few available qualifications are not taken into account.

What is the task list in an agile environment?

Even in an agile environment, dependencies need to be identified and taken into account. Here, for example, SCRUM teams already take into account how dependencies between backlog items are represented in the overall backlog planning. The split of the backlog items can be done initially by the product owner, but should be validated by the entire agile team lastest during the initial sprint planning. Even within SCRUM teams, dependencies are constantly re-evaluated, since the continuous prioritization of user stories can possibly lead to additional identified dependencies. Splitting user stories without creating additional dependencies is an important skill of the SCRUM team. However, it should be taken into account that the user stories are not only split according to the technical paths, but that the functional questions are also taken into account. Otherwise, the agile approach will be counteracted. Because then an early and small-scale delivery of functions is no longer guaranteed. As already mentioned, this balancing act of splitting up is a core competence of the entire team.
