estimating in ideal days
- How long something would take if:
1. It is all you worked on
2. You had no interruptions
3. Everything you need is available
- The ideal time of a football game is 60 minutes (4 quarters X 15 min)
- The elapsed time (duration) is much longer (3 + hours)
Planned activities are affected when people spend time to read and answer email, make phone calls,
attend meetings, address personal issues, attend training, support releases, management reviews,
take sick time, enjoy vacations, perform task switching, assist in fixing software bugs, attend
buddy/peer reviews, and participate in other activities that interfere with meeting commitments.
