Explain why the IB design cycle model is not linear and why it is
iterative in practice, thus making it representative of design thought and
The IB design model emphasizes that designing is not linear process. Evaluation, for example, will take place at various stages for the process, not just at the end. Similarly, ideas for possible solution are not only generated at the generating ideas stage; some good ideas may develop even as early as the identifying needs stage. In practice, it is impossible to separate the stage of the design process as clearly as the model suggests.
