Having selected the focal starting point, or points, we must now turn our attention to the actual design procedure itself.

Many excellent systems of design techniques have already been evolved, aimed at achieving the ideal solution in a series of logical steps, and these help many people. Others find them valuable but for another reason. For them, such a system is of little use in actually creating anything new as they do this by their own untrammelled inventive flair, but, having settled on their design, they subsequently find some of these techniques most useful in proving how logical it all really was. Serving it up in that way often makes a better impression on bankers and accountants.

In view of the excellent methods already available I shall not attempt to provide yet another; my aim is a humbler one. I want to give a little help to someone whose mind is more or less a blank. An aid to get the party going, while, at the same time, leaving all the doors open for unexpected but welcome guests in the form of sudden creative inspirations.

As we have already discussed, your strategy will be to concentrate on a selected frontier, as the impact of the whole project and its multitudinous requirements is too intimidating.
