DeMarco, Tom. Controlling Software Projects. New York: Yourdon Press, 1982. This book contains much of the inspiration for this chapter's discussion of the shape of software schedules. DeMarco paints a humorous and sometimes painfully vivid picture of current estimating practices—which as far as I can tell haven't changed since he published his book in 1982. He lays out one approach for improving estimation and scheduling.

Martin, James. Rapid Application Development. New York: Macmillan Publishing Company, 1991. This book presents a different perspective on the core issues of rapid development for IS applications.

Smith, P.G., and D.G. Reinertsen. Developing Products in Half the Time. New York: Van Nostrand Reinhold, 1991. Although not about software development specifically, this book contains many insights that relate to developing software products more rapidly. Chapter 3 contains a full discussion of the "fuzzy front end."
