Yes, you can have a VMM less than zero. In the simple form of VMM the lowest level is a zero; However, in more complex instances, you can have a negative VMM. Before we get into the explanation, let me emphasize that a zero level VMM has a core business function and either has no vision or direction at all, or is at least not communicated to the organization.
A negative VMM occurs when your organization is operating its core business under the premise that there is a vision for the organization and the perception is that employees are operating from that perceived vision. When this happens over a period of time without proper communication of the organizations vision then operational separation may occur. Operational separation is when the vision is so distorted over time that operational units that should be performing core task as a single unit, start operating as separate units. Since the definition of a Level 0 VMM is: no vision or direction of a current business state...when you have two "business states" because of operational separation and the organizations VMM is a Level 0 then this combination will result in a negative VMM.
