Cost of Delay Prioritisation

(also known as CD3 or WSJF)

❓What is it

  • A prioritisation approach to make value and urgency more visible. It quantifies an opportunity cost in economic terms when work is delayed, enabling more objective decision making and trade off decisions.
  • There are two basic inputs required to work out the Cost of Delay:
  • 1. Value – Calculate a value of the benefits per period, based on an estimation of the work’s economic value to the organisation over a given time period.
  • 2. Urgency – An understanding of the work’s urgency: when do the benefits start to occur or deteriorate? Is there a calendar peak period that is critical to make ?

👥Who

  • The technique is typically used by a product manager as part of prioritising their product backlog and gaining consensus across stakeholders with conflicting viewpoints of what work is most valuable

🛠 Running the technique

  • Calculate a benefits figure for the change derived from value definition work already undertaken.
  • Work out when the benefits would start being realised or when the expected benefits may deteriorate if at all
  • Derive a Cost of Delay figure using a standard period of time e.g. month
  • Repeat the steps for initiatives or backlog items competing for the same capacity
  • This provides an objective comparison on which to achieve transparent consensus
