I've long believed that one should be an expert first; a speaker, author, coach, etc. a distant second.
Books for me are never a destination; they're always a journey. It takes me roughly four years to think about, ask a lot of questions, interview executives, socialize an idea with people I like, respect, and trust to finally come up with the right mix of content to capture in a book.
At some point, you've read enough, spoken enough, thought enough, consulted, and coached enough about a topic that you feel like you have something to say.
Once I have my Table of Content (TOC) of key ideas that are interesting to me, I begin researching social science references, write, edit, rewrite, reference, insert case studies/examples, work with talented graphic artists to visualize key ideas, and put the finishing touches on a book such as a book cover design, the index, and jacket info.
If you go the commercial publishing route with the recognizable imprints (Wiley, McGraw-Hill, etc.), get ready for a painful if not lethargic process - your ideas MAY actually come out in 12-18 months; publishing, unfortunately, is one of the last remaining antiquated industry sectors ripe for real innovation if not disruption.
If you go the self-publishing or even the hybrid (self-publishing with a more recognizable imprint), you'll get your ideas out sooner without the cache of a globally recognized imprint.
In either case, don't expect much marketing or support, a great "customer experience," or the misperception that people will be breaking down your door to engage you.
After ten books, I've learned that writing a decent book is half the battle. The other half is promoting the heck out of it.
