For more than 25 years, I have been a consultant and industry analyst in the enterprise software market. I have seen many companies come and go. In my newly published book, "Smart or Lucky? How Technology Leaders Have Turned Chance into Success," I have analyzed what makes the difference between companies that turned their luck into sustainable success and those that failed. Many of the 25 or so companies in the book are companies that I worked with or analyzed while they were emerging. I was privileged to have a front-row seat within a very dynamic industry.
