So the assignment is done which means I have about a week to recover before starting the next one. That is going to be more difficult: it has to be both a defence and a proposal for my dissertation: what I intend to do, why, what bit of original research I intend to do and how. I have to push back the frontiers in the quality field. For the last two weeks, I've been eating, drinking, writing and dreaming about 5S and also wondering if it is the right tool for the use I'm proposing. I'm torn between having to do all the reading again or having to defend a position which could turn out to be vulnerable. Watching the fireworks race into the sky against the horizon of the sea and the hills is not helping matters.
