Techies are cursed by the reluctance to create documentation. Most environments are a SOP (Standard Operating Procedures) desert. In every job in which I have started, no-one has ever given me a SOP of the services being provided. I would have to "sink or swim." Most techie managers who were treated in this manner, reinforce the behaviour by treating their subordinates in a similar manner. In reality they even go further to ridicule those who create documentation as bureaucratic. By this they imply that it is a waste of time but often the underlying reason is to be able to be a hero, as when the sh1t hits the fan, they are the only ones able to resolve it, as all the knowledge is in their heads and not on paper for anyone else to attempt to resolve.
