With every SharePoint solution being delivered, there is comes a change management effort that requires not only organizational, but also behavioural change on the part of the participants. You can set up the finest SharePoint solution on the planet, but if people do not take to the SharePoint solution, nothing will change and the effort will be lost.
“To get a horse to drink water, you make the horse thirsty”
Successful adoption of any SharePoint solution enables users with self determination. Irrespective of user task, or position, self determination needs three factors, which is competence, relatedness and autonomy. These combined produces motivation. And, when you have self determined people, support requirements are properly defined, people understand how the solution makes their tasks more productive, training strategies are easier to develop and sustain. A key person requirement, which is not technical, is the SharePoint Champion; whose objective is to foster self-determination amongs their peers; a person elected to help drive adoption of SharePoint solutions, elected by the business, and for the business.
I wrote a pretty detailed piece on the topic of SharePoint Champion being a vital role, because I think it is so important to provide successful service delivery of SharePoint solutions. To see this, check out on Microsoft TechNet Newsletters article posted here:
