Job descriptions are intended to support managers in employee deployment, personnel development, and the design and optimization of the organization. Traditional job descriptions, with their bureaucratic and sterile listing of tasks, are not very suitable for this purpose. However, if the job description is IT-managed and focuses on the truly important tasks of the position, it provides valuable, analyzable information for management and organizational work. If the job description also serves as a basis for employee evaluation, it becomes an active management tool. It offers insights into the strengths and weaknesses of employees and the organization. With many formulation aids and text modules for daily use in management and HR practice. New in the 3rd edition is the chapter: Leadership Conversation: The Role Model at the Center.
