Master the Art of Estimation

• The author believes that effective estimation techniques should capture both time and uncertainty.
• The author's technique involves breaking down work into smaller tasks based on complexity and using labels to indicate time estimates.
• The author also estimates uncertainty by applying a multiplier to the expected time.
• The specific labels and multipliers used are arbitrary but should be consistent over time.
• The author recommends aiming for low uncertainty in order to produce a more accurate estimate.
• If there are externalities, such as other projects waiting on the current one, a wide range of estimates may be too broad.
• Refining the estimate may involve breaking down extra-large tasks into smaller ones or reducing uncertainty on highly uncertain tasks.
• Time-boxing can be used to invest time in scoping or de-risking in order to produce a better estimate.
• Tracking actual time can be used to refine and train estimation skills over time.
• Other estimation techniques include PERT, Monte Carlo, and Wideband Delphi.
