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%.
