Cost of Delay: The Most Important Metric You're Not Tracking

Every week of delay has a dollar cost. Once you calculate it, prioritization becomes obvious.

By Richard Ewing·

What Delay Costs

Cost of Delay = Lost revenue per week + competitive disadvantage + customer churn risk + opportunity cost.

Example: a feature expected to generate $100K/month in revenue, delayed by 3 months = $300K in direct cost of delay plus competitive window risk.

Use CoD for prioritization: WSJF (Weighted Shortest Job First) = Cost of Delay / Job Duration. Always do the highest-WSJF item first. This alone can improve engineering ROI by 20-40%.
