I thought the entire book could have been written in less than 10 pages. For years I worked as a manufacturing engineer, so documenting your processes is kind of second nature to me. On the other hand, I hated bureaucratic systems like ISO 9000, so my advice is always to do the minimum necessary.<p>For startups, just keep simple documentation of essential processes. For example, I rarely had to process refunds through PayPal, so I would forget how to do it. I kept overlooking the refund link. So I made a screen shot, circled the link, and saved it in my process documentation folder. Basic, but effective.<p>For other processes, I have written documents, flowcharts, and checklists, depending upon how complex the process is. If you have 1-2 people in your company, you're doing it for your own benefit, so there's no need to be formal.
