70, 20, 10
I've been talking about 70, 20, 10 models for a good time, and it seems that it's applicable in a wide number of different contexts. Generally, it relates to the idea that the majority of time, focus, attention or resources should be focused on established practices or core methods, but room should be left for both extending those core approaches and taking them in new directions, but also for completely new ideas and input.
