Over the past 20+ years, I have read few books which provided the kind of business revelations that Michael E. Gerber’s seminal work did. His book, The E-Myth, illustrates with elegant simplicity, the fact that entrepreneurs must “work on their business”, not “in their business”. This lesson can be used in project management. You have to see the total picture as a project manager. In effect, you have to work on the project, not in the project. Rather that doing a marginal job in explaining this, I suggest that you read the book.
