5 Case studies

Only practice will tell if and how a method really works. The value stream approach and its various possible applications and operational modes are therefore illustrated in detail by way of several project samples. For a better illustration of the wide range of possible applications of value stream design, different project types based on industrial projects were chosen. These sample projects are rather complex and comprehensive in order to better illustrate the factual courses of action applied.
