Not one for one
Spreading work over more time periods is not a one for one relationship
- Because of the "startup time" experienced each day
- Which is why overtime is attractive
- But only within limits
- Or for short bursts
- Because of individual "burnout"
Rules of thumb
- Doubling a resource may save only 25% of the time
- The last 10% may take 20% of the total effort - or more
