Iterative Design Process

So far, most of you have been focusing on your developmental process that will be used to generate design variants. You will then need a way of comparing your variants. So at this stage, it is important to start working on your evaluation process. It is important that you identify at least two criteria for evaluation, so that you can plot your design variants on your pareto graphs.

At the end of semester, we will be focusing on the your iterative design process, rather than the final design. It is therefore vital that you have more than one iteration - preferable more than ten iterations. To do this, you need to have both a developmental process and an evaluation process.

Since the focus will be on the process, it is important not to get caught up with trying to solve everything. At the moment, many of you are trying first to solve everything before starting on your iterations - if you do this you will never get there. You need to start iterating as soon as possible - even if the iterations are based on a very simple developmental and evaluation processes. You can then gradually add in more complexity as you go, and only where it is really necessary. It is better to have a simple design idea where the iterative design process can be applied successfully, than a complex idea with only one or two iterations.
