The introduction of process management is a classic change project that affects the entire organization at all levels and in every area. Many stakeholders, ranging from top management (“Chief Process Officer”) and middle management (“Process Manager”) down to individual employees, the “Process Experts,” must be involved. Changing and optimizing processes primarily means “changing people” and motivating them towards process-oriented collaboration. This chapter describes approaches to process-oriented organization within companies and the optimization of processes. In addition, it introduces the various roles and stakeholders, which must be developed to varying degrees depending on the size of the company. Special emphasis is placed on project organization, which is particularly important when project management concepts are being introduced for the first time. The chapter concludes with review questions and an exercise.
