In this part of the Delft Design Guide we present some methods, tips, deliberations and so on, on more generic topics that are of interest while learning and practising design. The topics are not specifically attributed to one particular phase in the design process, but useful and applicable in a more general sense. As for the other parts of this Design Guide, the  reader should be aware that this material offered does not cover all the knowledge of these topics but serves as a starting point for further study.
