The governance model defines who is allowed or entitled to control over the organisations assets. Assets should be regarded in the broad sense covering all model layers. Assets include product & service definitions, customers and channels the organisation serves or wants to serve, the definition and execution of processes, the application facilities and also the application infrastructure. The combination of all these assets and usually the distributed control over them is what makes governance such a difficult topic: the right combination of assets is required to create the products and services the organisation exchanges with its environment and at the same time there is usually no central point of control or governance. The form in which the governance model appears can vary to a large extent. It is either a plain text representation of the governance rules and demarcation or it can be the outline organisational structure that defines which organisational parts (divisions, departments, and sectors) are responsible for delivering particular services that are used by other organisational parts.
