For each of the following, please define these as either work breakdown structure, triple constraint, 100% rule, or 15-15 rule.
1. The process of identifying all tasks needed to complete a project.
2. Three factors that constrain information technology and other projects: cost, scope, and time.
3. A rule requiring 100 percent planning of all tasks, including all of the internal, external, and interim tasks.
4. A rule suggesting that if a project is more than 15 percent over budget or 15 percent off the planned schedule, it will likely never recoup the time or cost necessary to be considered successful. At this point, a decision needs to be made on if or how to proceed.
