Details of the business processes are captured as part of the model creation exercise. One of the most important uses for the information is that it can be delivered directly to the point of need when required. As the information is held in a single repository, it is very easy to manage version control.
Your Operations Manual is on-line and immediately available when required.
Thus organisations can not only deliver work to employees or work participants, but can also deliver the explanation about how that work should be done.
