e could object I handed him a pen and a napkin and asked him to write down the names of companies and concepts he read about that have anything to do with the semiconductor business – in 30 seconds.

As you keep reading more materials, you’ll have more questions than facts. Your goal is to first turn the questions into testable hypotheses (guesses). Then see if you can find data that turns the hypotheses into facts. For a while the questions will start accumulating faster than the facts. That’s OK.

Drawing a diagram of the relationships of companies in an industry can help you deeply understand how the industry works and who the key players are. Start building one immediately. As you find you can’t fill in all the relationships, the gaps outlining what you need to learn will become immediately visible.

My suggestion was to use the diagram in the third mapping pass as the beginning of a wall chart – either physically (or virtually if he could keep it in all in his head). And every time he learned more about the industry to update the relationship diagram of the industry and its segments. (When he pointed out that there were existing diagrams of the semiconductor industry he could copy, I suggested that he ignore them.

What he didn’t know was that this was only the first step in a ten-step industry mapping process.
