In order to reduce these iterations, we need to detect such unpredicted problems as early as possible in the design process. As a consequence, reaching a final satisfactory product can be time-consuming and cost-inefficient because of additional iterations between design and design verification in the development process. Unpredicted problems could be hard to solve or even hard to detect. Although each subsystem has clear definition and it is supposed to behave as specified, designers can still be surprised by unpredicted problems that dete- riorate the performance of the product. Subsystems are clearly defined and understood because they belong to one small mod- ule of a product. Then, the design verification starts by gradually integrating and testing components and subsystems. Thirdly, the overall system concept is quickly decomposed in subsystems that provide the design with more details and eventually components are designed. In the V-model, a product design consists firstly of requirements analysis, which considers the possible conflicting needs of various stakeholders, secondly of the system design that derives system specifications from requirements and chooses main concepts of the product. As a conse- quence of this product complexity, the product development process is becoming complex as well due to the multiple stakeholders involved in the process and their rapidly changing roles.Ī well-known procedure for product development is the V-model. This com- plexity is due to the ever-growing market demand for new and innovative products with multiple functionalities, to the product size and component density that grow to a level that only a handful of experts can deal with, and to the multi-disciplinarity or inter-disciplinarity nature of products such as. In the last decades, the complexity of products has increased exponentially.
