themselves explaining at acocktail(ab)party,say,that they are in computers,or in telecommunications,or inelectronic funds transfer.The implication is that they are part of the high-tech world.Justbetween us,they usually arent.The researchers who made fundamental breakthroughs in thoseareas are in a high-tech business.The rest of us are1713 of their work.We use computersand other new technology components to develop our products or to organize our affairs.Because we go about this work in teams and projects and other tightly knit working groups(cyd&:ev4p!z),we are mostly in the human communication business.Oursuccesses stem from good human interactions by all participants in the effort,and our failuresstem from poor human interactions.The main reason we tend to focus on the 1723 rather than the human side of the work isnot because its more 1733,but because its easier to do.Getting the new disk drive installedis positively trivial compared to figuring out why Horace is in a blue funk(ef)or why Susanis dissatisfied with the company after only a few months.Human interactions are complicatedand never very crisp(%g,%&!h)and clean in their effects,but they matter more thanany other aspect of the work.If you find yourself concentrating on the1743 rather than the1753,youre like thevaudeville character(*io)who loses his keys on a dark street and looks for them on theadjacent street because,as he explains,The light is better
