Often it is a requirement that the active stage duration is tracked on a dashboard or the like. However, the duration field out of the box, at least in my experience, doesn’t do what you think it does. In fact, if you look at the default calculation what it is doing its actually trying to calculate the difference between the created on date, and the completed on date-which is calculating the total time from BPF start to BPF finish. What most people actually want to see is a measure of how long a record has been at a certain stage of a BPF. So that’s what will be discussed in this blog post; how to REALLY calculate duration.
