Appalling but true. Though our white collar self-esteem may bristle at these words, in fact I think engineering is very much like the trades practiced hundreds of years ago. An engineer not constantly involved in self-education will be obsolete in very short order. One thing we never discussed in college was drawings - amazing, since most engineering output is nothing but drawings. Sure, we sketched a few simple schematics and analyzed blackboarded circuits ad nauseam, but somehow never addressed the issue of creating, maintaining and updating the drawings that are the product of our work.
Every small company passes through a phase of creative chaos.
Crank out a few sheets of Orcad schematics and hand-annotated assembly drawings, and ship the product . New hires, not so intimately familiar with the product, now are expected to build and maintain the products, working often from memory. This is a classic case of the company's systems breaking down. My company went through this evolutionary phase. Hundreds of drawings accumulated.
