Anyway, now that Christmas is out of the way I am going to put CPA into practice, years after I learnt it at engineers' school; not that I was an engineer. I was on the dole and they let me on the course to make up the numbers.
Basically it is about planning a process, taking into account those conditions which will have to be met in order for the process to begin, or progress to the next stage. It helps you to anticipate order delays etc. It is common sense really, but putting the process down on paper helps a lot. It also helps you decide what the most efficient use of time, in the event of a delay, will be.
For instance, I am mounting the finished engine on the chassis before completing the wheel arches because I need some critical dimensions which I won't have until the wheels are on. I need the front scuttle on for this...but as I say, the engine must go in first, and before that, the chassis must be on wheels and suspension. Before the wheels can go on, the brakes must be done..and that process is awaiting the pull-off springs. This is an "all for want of a horseshoe nail" situation. So: pull-off springs ----brakes ---wheels----suspension----engine----scuttle----wheel arches -----rear of cab. First I need to find or make those damned springs, and while I am wating for them to arrive, what would be my best use of time? Differential clean-up, I think.
When I get home, it'll be all systems go.
