Estimating Project Duration

The guys over at Open Loops have written a post on estimating how long it takes to complete a project (I knew algebra would come in handy one day!).

Basically you use the following formula to work out the duration:

Te=(To+4Tm+Tp)/6

Key:

  • Te = Realistic time estimate
  • To = Most optimistic time estimate (the Sunny Side estimate with no setbacks)
  • Tp = Most pessimistic time estimate (with every obstacle happening)
  • Tm = Most probable time estimate (this makes you think realistically; some setbacks happen, others don’t)
