These actions are referred to as functions, and are carried out on given objects (so-called work objects). subgoal Task analysis is the systematic penetration of the Aggregation level 1 tasks to be distributed. The task analysis stems from the total task of an enterprise. This, in turn, can be divided into concrete subtasks through a multi-step sub- analysis according to specific criteria, until a level of subgoal elementary tasks is reached. As a result, the total task Aggregation level 0 can be grasped with a greater degree of precision. Task synthesis is the systematic, goal-oriented aggregation of the subtasks identified in the task Legend: analysis, which then creates positions and the Task corresponding labor division forms that “generate the New task organizational structure of the enterprise through their Required information/control flows connections”. Alternative information/control flows Source: Schreyögg 2003, Schlick et al. 2010, p. 437 © Chair and Institute of Industrial Engineering and Ergonomics, RWTH Aachen University 2 - 9 Task Analysis ... divides the total task stepwise into portions through use of five dimensions. This results in numerous subtasks of varying degrees of aggregation, differentiated according to individual perspectives. 1 The performance analysis is used for the acquisition of subtasks according to their related operations and functions 5 (e.g., sawing, grinding, hammering). 2 The goal of the functional relations analysis The operational procedures extend to objects, is the ordering of tasks according to their e.g., the products to be developed and position in the performance process. Tasks processed in terms of quantity and structure, must be distinguished depending on Dimensions during the object analysis. whether they are direct – primary of Task Analysis purposeful tasks (uniquely value-adding) 3 or indirect (management based). Rank analysis signifies the classification of tasks into execution and decision tasks. 4 Phase analysis signifies the formation of subtasks according to the three phases of planning, implementation and controlling/organizing.

According to Kosiol, each performance must be analytically dissected until the elementary performance level – performance of tracts of the lowest order – has been reached.
