The author also states that having many small models is less desirable than having one large module that does the same thing. This Chapter is concerned with the difficulties in project planning. The author presents a detailed analysis of the product cost scheduling. I was completely confused by this and still do not understand it.

In this chapter the author discussed system planning. He states that the first design that is built usually needs much improvement. Therefore in planning a system we should also plan to throw the first system away. Although it seems to do so this chapter does not conflict with Chapter 6. The idea in this chapter is to distribute the second system and not the first.
