Query: Great book, experienced authors

I had the pleasure of speaking with the author (Don Widrig) over the phone prior to a job interview and he helped close the loop on some of the concepts presented in the book. I went into this book not knowing that use cases are used in the requirements analysis phase because honestly, I never did that phase properly and even my masters level courses didn't provide this information.The book outlines the proper steps to gathering requirements from a use case perspective and provides numerous examples that you can actually apply in the real world. I would definitely recommend this book to any systems engineer, business analyst and even people interested in understanding process mapping more.
