ABSTRACT
The systems analysis approach to designing the case studies is a potential tool to coordinate development activities in such a fashion that the validity of findings can be assessed both from a practical perspective and from a scientific perspective to reveal strengths and shortcomings. The general expected outcome of the system analysis procedure is one or several system models. System thinking views the world as a complex system of interconnected entities where 'everything affects everything'. The system components are interrelated and interdependent and cannot exist independently. When designing case studies using a systems analysis approach it is vital that stakeholders participate in the process of designing the case study as well as selecting measures and representations. The chapter outlines measurement model corresponds to the major expectations. Formal measurement theory suggests two theorems: the representation theorem and the uniqueness theorem. The uniqueness theorem states that every empirical relation has only a few appropriate ways of representing a numerical model.
