As for every article in particular, the triggers can be different. The idea of writing an article on the communications plan
came to me after a failure. I asked myself, "Am I doing something wrong?". To answer the question, I had to analyze and systematize my experience in plan design. When all the systematizing was done, and I made sure I did nothing wrong, I realized that there was enough material to create an article. A thing you did for yourself can be useful for others as well.
