Writing a book or an article is a demanding process in the best of circumstances. We must balance a number of internal and external factors. We must figure out how to convey our insights and experiences, research and analysis, in writing. At the same time, we must interface with the external world: schedules and deadlines, editors and publishers, and ultimately with our readers. We add another set of factors when we work with co-authors. How can we navigate all of these dimensions in ways that allow us to collectively produce our best work?
