So having established a model, how do you use it? The entry point can be almost anywhere. It's possible to start with various elements of this model and extend to embrace the whole model. If you have just taken stock of where you are with your current project and want to know what next, use the holistic model as a template. Perhaps you should take what you've learned and build on a new or existing knowledge asset, or perhaps it prompts a request you can make of the network.
