The Scrum guide tells us that its roles, events, artifacts and rules are immutable. This is fine if you want to ensure you are doing Scrum. Scrum is based on the philosophy that following its roles, events, artifacts and rules will facilitate Agile. While this is often true, doing so sometimes either cannot be done economically or at all. Cross-functional teams and being able to plan ahead is not something that can always be accomplished. Just as important, sometimes Scrum’s roles, events, artifacts or rules are not appropriate for a particular situation.
While Disciplined Agile Lean Scrum does not have a pre-determined set of practices they still have specific objectives. Changing any practice arbitrarily, however, is not advised. There is a reason (objective) for the roles, events, artifacts, and rules. While it may be advisable to change one, the new practice must achieve the original intended objective.
- Are you having challenges with the practice because it is being done poorly? If Yes, then inspect and adapt and see if you can do it better. If No, continue.
- Is there something else in the organization that is causing us this problem? If Yes, then see how to fix that or at least influence the fixing of it. If No, then continue.
- Is the ecosystem that the team finds itself in causing the problem? That is, are people not collocated when they need to be or are required skills missing? Can you improve on this? If yes, do so. If No, continue to see if another practice that works within this ecosystem will work better (see next step).
- What else can we do that meets the same objective of the practice? If there is something else you can do, then try that. If not stick with the practice until you learn more.
There is no definitive set of alternative practices to Scrum. That is the entire point. But it is worth investigating a few of them to illustrate how Scrum as Example can be used.
How to tell if a change is better
There is a set of underlying principles that can provide an indication if a change will improve things. This is always in theory to some extent, because even if a change will improve things if made, there are often side effects caused by people not adopting the change that work against it. We therefore must always be diligent and validate any change we make.
The measure to use is the value stream impedance scorecard. In a nutshell, the VSIS indicates how much resistance the system will impose on work being attempted. It is based on what improves total value manifested. Lowering this resistance usually results in more value manifested.
So What If It’s Not Scrum?
Of course, following the procedures may take you out of the arena of what Scrum defines. But you should be more concerned about being effective than if you’re doing Scrum. See Rethinking ScrumBut and ScrumAnd for more.
