This thesis applies the systems engineering approach, which provides a good basis for the technical-physical consideration and the lighting of the management processes. That allows the identification and tracking of the DIF along with the life cycle during the development. Thus helps to understand how the DIF are created, developed and which decisions are made on the basis thereof. It is important to keep track of how changes of the DIF affect decisions (design, management, etc.). In order to finally identify and track the DIF, methods from requirements engineering - more precisely traceability - are used to formalize the identification and analysis of D&I. Since the DIF are network-dependent and the analysis of the flows is necessary, the network and graph theory is used to translate the D&I into a neutral language. That is how DIF becomes analysable and useable for process optimization. The mathematical analyses also increase the chances of measuring and evaluating the dependencies, making DIF visible and understandable for the individual developer as well as the company. The complexity can thus be reduced to a manageable level.
