The most memorable standards meeting I ever participated in was the P1149.4 Working Group meeting at ITC in 1994. We had informal and very encouraging results on how this proposed standard would compare to IEEE Std 1149.1 based on a case study of a customer's product. We also had a memorable discussion on legal aspects of standard development, which will prove to be historic as an impetus for the IEEE to have a better guideline or policy in this matter. The lessons I have learned are too many to list. The technical ones are easy to identify, but the more significant lessons are in working with individuals and organizations.
People are intriguing, and organizations are, well, frequently a pain in the neck.
The best way to get things done is to work with people, then find ways to navigate through the maze of organizational structures and their peculiar idiosyncrasies.
