- Process Engineers (those who define and document the processes) and
- Practitioners (those who have to follow the processes).
But keep in mind, that an approach that works in one organization for achieving “buy-in” may not work in another. You really need to work with the organization and jointly determine the best method for the organization. If most of the practitioners, for example, do not relate to visual process flows, then the “swim lane” approach may not work.
