In part 1 and part 2 of this blog series, I discussed how organizations benefit from Kanban but leave much value on the table by not embracing its full potential. Making the changes to implement a true enterprise-wide pull system is very possible so what is getting in the way of progress?
In part 1 of this series I described the incredible benefits that Kanban is providing to organizations around the world. I asserted that far greater gains could be achieved if only Kanban initiatives were fully embraced and moved to a deeper level of “pull” at enterprise scale.
But how do we even know if we are achieving a complete pull system or not?
This is part 3 in my series dissolving our fascination with prioritization using Cost of Delay and related queuing theory equations such as WSJF (Weighted Shortest Job First) or derivatives thereof such as CD3 (Cost of Delay divided by Duration). I truly believe we all need to be protected from this latest cult. I don’t think it is serving the Lean or Kanban movements well – people simply can’t generate reliable numbers for these prioritization equations and even if they could the underlying mathematics isn’t sound. It’s going to take me 6 parts to fully deconstruct the futility and uselessness of these methods. This is part 3, the final part examining the denominator in such equations, the duration …
