Calculating Cost of Delay
with Marty Bradley

WRITTEN BY Dave Prior

This is the second interview in a series we are doing on Cost of Delay. The first interview, where Jim Hayden provided an overview of Cost of Delay can be found here: http://bit.ly/2lUDWFR

In Part 2 of the series, Marty Bradley explains how Cost of Delay actually works. During the interview we discuss things like Weighted Shorted Job First (WSJF), how to determine relative Business Value of different features or projects and how to evaluate that value against different factors like risk.

During the interview Marty refers to two different graphics that help explain Cost of Delay. Here are links to the two graphic files*:

* These graphics are based on examples Marty was referencing in the interview. The originals can be found here.
