For what its worth, here's something that might help in analyzing the 
situation some more. Its an analytical approach called "mission and core 
competencies (MCC) matrix".

I do not have rights to distribute a copy of the paper, so you'll have 
to look for one in your own libraries. Here's the abstract and a link to 
details.

The MCC decision matrix:: a tool for applying strategic logic to 
everyday activity

Abstract:

Proposes the MCC decision matrix as a modern equivalent of the original 
Boston Consulting Group (BCG) portfolio matrix. Focuses on the key 
questions of mission and core competences which define the axes of the 
matrix and give it its name. Unlike the BCG matrix, the MCC matrix can 
be used to assess the relative merits of any competing claims on 
resources, not just those associated with product/ market segments or 
strategic business units. Also the validity of the matrix itself can be 
challenged and its expression modified. Claims that the matrix can be 
applied to sub-units at any level of the organization and is therefore a 
powerful tool for applying strategic logic to all types of 
resource-allocation decisions throughout an organization, ensuring their 
optimal contribution to building competitive strength. Presents a 
nine-cell directional policy matrix as an alternative form.

Of course, the key dependencies are that you actually *know* what the 
mission and core competencies are.
