5.What are the advantages and disadvantages of traveling light, of producing just barely enough documentation for your system? Consider three scenarios: the original development team stays on to continue working on the system; the original development team changes slowly over time with some people leaving and some new people coming on to the team; and the original development team disperses and the system is assigned to another team to maintain and support. How light can you travel in each of these situations?

6. Discuss the trade-offs between a "big design up front" approach to modeling versus an evolutionary approach. What are the advantages and disadvantages of each? What type of skill set would be required for each? Why?
