Step 5 - 2
The difficult-to-estimate tasks
- Some tasks will still be difficult to estimate
- Seek expert help, use ranges
- Document areas of high uncertainty (risk)
- Always aim for the "Most likely" duration
- I.e. don't build in contingency at every step, or your project will not "fly"
- Always be realistic - you can refine on the second pass!
- And make appropriate contingency allowances later
