Resources are always finite, so leadership is pretty critical in this regard. You need to protect some resources to have a dedicated focal point and team. Our department and others in the system have made that decision.
In my organization I have an analyst who is responsible for this pretty much full time. Throughout my organization I also have the expectation that my directors and their analysts—for example, in cabinet affairs—are applying GBA, and the resources become a part of their ongoing and daily business.
With respect to training, though, we did consider whether or not we should make that online course mandatory for all staff in the organization. I will share with you that the decision to not do that was in part because of a resource consideration—time, mostly. We thought that as a first step in terms of a mandatory requirement, we would focus that training on those individuals in the department who would have a lead role, rather than on everybody across the entire organization.
