Having a high-ranking Patron who supports a wiki provides a level of authority that can enhance the prospect of success.
Occasionally a senior figure in an organization initiates a wiki project. More often, the initiative comes from below, but the support of a senior figure is sought. By letting it be known that they support the project, a Patron gives permission for others to be involved and for resources to be allocated to the project.
A Patron is particularly important in a corporate environment, where control of IT resources and competition between organizational units may otherwise discourage participation.
An employee who already knows the CEO explains the benefits of a wiki, and perhaps demonstrates a working system within the organization. The CEO agrees with the idea and encourages the employee to continue. The CEO becomes a Patron by “giving the nod” to the initiative. The CEO may have no further involvement apart from allowing it to become known that they support the use of a wiki. The initiating employee can encourage other people to become involved by explaining that the CEO thinks it is a good idea.
