Certainly the equation lean = software is a sound one, but who of us is really ready to at least reduce the quantity of paper we produce & use every day? In my auditor's career I've lived very few positive cases, & even now, working as a consultant, I'm seeing very few illuminated companies that find the paper they produced along the years quite unuseful. In particular, to make a case of it & to voice my thinking, I'm presently working at a predictive maintenance project of a dozen very expensive machines. Their operators say the machines are very robust, so the routive preventive maintenance would be sufficient for the next ten years or so. But there are no data on the previous ten or twenty years operation to confirm what they say; or, if there are any, they are buried in the Company's cellar, under tons of dusty volumes. So far, for the records having to be "readily retrievable". A second facet of the problem is represented by the the more or less natural dislike of my generation - I was born in 1950 - for software: we still want to touch things, generations next to mine are more abstratically-oriented. We are gradually retiring, and will leave room to the young, hopefully, and to methods to make & keep them more engaged, and give them equipment to have on-line or on-time information, and provide for timely feed-back. One, two, three: Customership keeps requiring for hard-copies, even CD's and PDF or JPG formats are looked at with suspicion. When I read of Dr. Feynman's recount of the Space Shuttle disaster, I was amazed that the on-board computer system, though redundant, was still working on valves, not semi-conductors. Yes, the solutions are in the software: maybe, more correctly, that the solutions are in the people who market and design software. The former often behave like demigods, the latter, almost as often, don't understand their customer's needs, or don't listen to them: it's requirements' twisting, or warping. Thank you.
