How the 3 Point Estimate Works in Doofer

The three point estimate formula is designed to calculate a more accurate time prediction by using three inputs:

  • Optimistic (O) – The best-case scenario
  • Most Likely (M) – The expected time based on experience
  • Pessimistic (P) – The worst-case outcome

Doofer then applies the 3 point estimate formula: (O + 4M + P) / 6

This gives you a weighted average that better reflects uncertainty, risk, and real-world variability.

    Why Use the Three Point Estimate in Project Planning

    • Provides more realistic timelines
    • Reduces risk of over-promising
    • Encourages teams to think through best/worst outcomes
    • Ideal for IT tasks, feature planning, and product sprints

    Doofer’s estimation template lets you input all three values directly in the table. It does the math for you and updates total time, cost, and margin instantly.
