In Chapter 7, we performed some systems engineering on HOLIS, our home lighting automation system. At this point, we still don't know very much about HOLIS, but we probably know enough to establish a first cut at the organization for our requirements information. Figure 15-5 shows that the team is using the following elements to describe the requirements for HOLIS.

You'll have the opportunity to see these requirements artifacts develop further as we advance the case study in later chapters. A sample of each is included in Appendix A.
