If the tasks in the area of investigation offer the decisive starting point for the project, a task breakdown is necessary. The analysis is performed according to five bullet points: Tasks, Objects, Rank, Phase and Purpose. The last three points apply to the content of each task, therefore they are only formally listed. Which tasks are to be performed on which objects is of factual importance for the task analysis. The task classification is used, if in the context of an organizational project the tasks of a job or an area are to be raised and represented systematically, the arising tasks in the project are to be seized and planned systematically. A task can be further specified according to the criteria of object and performance in an AND outline or an OR outline. This enables a systematic recording of subtasks, which can be done according to the usual procedures of as-is analysis (e.g. document analysis, interview, etc.). All tasks must be recorded in a systematic order, completely and in detail. Instead of the card technique and the grid sheet method, the task analysis can also be supported by software programs. The individual tasks are structured hierarchically and illustrated in an outline tree (structure diagram). This technique can be used for all organizational questions of the project, but it only shows the actual state and does not offer any solutions. (Source: Mehrmann/Wirtz)
