A question about handling scope changes in SAFe was posed recently on a forum I’m participating in (The SAFe Community Forum). This is a question posed regularly in training and on ARTs I’m coaching so I thought I’d provide my thoughts here.
A lot of people somehow get the notion that SAFe advocates for “limiting/controlling changes during the PI”. The main source of this notion is that we “Plan the Program Increment” and commit to a set of PI Objectives as part of PI Planning.
But remember one of the key SAFe principles is “Assume Variability- Preserve Options”. This applies within a PI as well. While it makes sense to create a baseline plan for the Program Increment, we should also be prepared for adjustments. After all, we want to “Welcome changing requirements, even late in development.”, remembering that “Agile processes harness change for the customer’s competitive advantage.”
Some people are worried about the Predictability Score – “We would lose points since we won’t tackle some of our planning PI objectives and won’t get credit for them”. Yes some PI objectives won’t be achieved but new objectives should be added or objectives can be changed to align with the changed scope. (Think for example we didn’t manage to hit the “Deploy MS Teams” but we added “Enable all clinicians to provide telehealth meetings using Zoom” as a change made in a PI during the first couple of months of the covid19 pandemic)
We do it by following strong priorities and small batches going into the PI and limiting the number and size of features in progress in early iterations so lower priority Features / PI Objectives are kept as options rather than already started.
The goal is to avoid situations where we want to change direction but there’s already sunk cost since we already started the low priority Feature. We don’t take the sunk cost into consideration when prioritizing, but it will mean that continuing down the planned path will win the WSJF more often. Might be easier for the ART but isn’t necessarily maximizing the value delivered.
Even more important than the mechanics of the answer is the mindset. If a question like this comes up – go back to the principles. Lean, Agile, and SAFe principles will help you think about the situation and what might be the right systemic way to address it.
So let’s say Product Management is considering a change. They have a Feature that wasn’t in the original Program Backlog or was and there’s something that changed about it. Product Management should use WSJF to consider what to do. The Cost of Delay and Job Size of these suggested changes should be compared to the Cost of Delay and (remaining) Job Size of the existing PI Scope.
And if at this point the WSJF score for the considered change is higher than continuing down the current path then it makes sense to go for the change.
