Before we proceed, a note on integration techniques is in order. In this model we have introduced an abrupt work stop. It is best, with project models, to stick to Euler integration. A consequence of this, which we will see later in this model, is that there will usually be some overshoot. We might do 101% of the work, for example. These overshoots are not problematic, and are of little conceptual significance, though for presentation reasons it is sometimes desirable to correct them. We will, in this chapter, focus on the important conceptual problems, not the details of computation. See Chapter 8 for more detail on integration methods.
