Trac Demo and Set-Up

Team Exercises

1. Create a requirements specification for a computer-based game of tick-tack-toe. Address all possible items of a requirements specification.

2. Exchange your specification with that of another team. Create a series of questions that will clarify the specification you received and return it. Are you surprised by the ambiguities in your specification?

3. Based on the questions you received, revise your specification (and keep it for next time).
