This makes sense at the local level while still being clearly connected to higher-level outcomes. SAFe’s formula isn’t in Reinertsen’s book. He calls this the Weighted Shortest Job First (WSJF). Third, they are surprised at how much consensus they can reach on the value. Let’s say cycle time is worth $25,000 a week. In contrast, there are many cases where technical debt will never have to be repaid, and other cases where it can be repaid at a lower cost in the future than the present. In general we have good intuition about things we have seen more than once. Is there a potential penalty or other adverse consequences if we delay? This approach is known as a weighted-shortest-jobfirst (WSTF) queueing discipline and it is discussed in the book, “The Principles of Product Development Flow.” The sequence of projects that will produce the best total return will prioritize projects with the highest cost of delay per unit of scarce resource consumed. If something has a very high cost of delay and it’s clearly a Small, just do it! . Would it be possible? For example support costs are typically proportional to sales volume. Three primary components contribute to the Cost of Delay: 1. Anders Sixtensson is a senior Consultant at Softhouse Consulting specializing on Lean Software Development and process improvement.

This price will be determined by intuition which, as I mentioned earlier, typically can vary be a factor of 50:1. Is there a potential penalty or other negative impact if we … Cost of Delay combines urgency and value – two things that humans are not very good at distinguishing between. Dividing by duration is the "shortest job" part, which makes it clear that 12 one-month projects could add up to more value than one 12-month … Our customer runs a portfolio of projects in parallel and tries to manage this pipeline of ongoing projects in such a way that the pipeline as a whole delivers as much business value as possible over time.
