Qu'est-ce que le Coût du Retard ?
Le coût du retard (CoD) est l'impact économique de ne pas livrer plus tôt. Chaque semaine d'attente peut signifier des revenus perdus ou une opportunité manquée.
- Quantifies the price of waiting in dollars per week (or month)
- Helps justify faster delivery vs. other work
- Supports prioritization when capacity is limited
- Pairs with CD3 (Cost of Delay Divided by Duration) for ordering a backlog
Contrairement au ROI simple, le coût du retard est sensible au temps.
Comment ça marche
- Delay cost — multiply value lost per period by how long you delay.
- CD3 score — divide cost of delay (per week) by implementation duration (weeks). Higher score = do first.
- Compare items — enter multiple backlog items; we rank by CD3 so you see what to prioritize.
Formules
Total cost of delay
Total CoD = (value per period) × (delay duration)
Total CoD = (value per period) × (delay duration), after converting both to the same time unit. Example: $25,000/week × 6 weeks = $150,000 lost.
CD3 (Cost of Delay ÷ Duration)
CD3 = (cost of delay per week) ÷ (duration in weeks)
CD3 = (cost of delay per week) ÷ (duration in weeks). If Feature A loses $40k/week and takes 2 weeks, CD3 = 20,000. If Feature B loses $30k/week and takes 1 week, CD3 = 30,000 — build B first.
Cas d'usage courants
- Product backlog prioritization: Rank features by CD3 when the team cannot do everything at once.
- Executive decisions: Show the dollar cost of postponing a launch or compliance deadline.
- Agile / Lean teams: Make trade-offs visible using economic framing instead of gut feel.
- Sales & operations: Estimate revenue at risk from delayed tooling, staffing, or process changes.
FAQ
CD3 stands for Cost of Delay Divided by Duration. It is a prioritization score: economic urgency per week divided by how many weeks the work takes. Higher CD3 means higher priority.
Use lost revenue, gross margin, or a weighted score from user value + time criticality + risk reduction. Many teams start with a rough revenue-per-week estimate from finance or product analytics.
They are related. Opportunity cost is the value of the next-best alternative. Cost of delay is specifically the economic harm from waiting on a particular item over time.
Weeks are a common standard in lean product development. This calculator converts days, weeks, months, and years automatically so you can enter values in whatever unit fits your data.
