Strategic organizational support systems enable and support unstructur
ed reasoning and communication within organizations. Such argumentatio
n-based unstructured transactions can be used to continuously maintain
a cognitive model of the organization. The model can be subjected to
a prescriptive theory, in order to diagnose good and bad patterns in o
rganizational cognition. Because semi-autonomous groups need to form a
nd then dissolve when tasks have been completed, the relationship betw
een group members (who may be inside or outside the organization) can
be formalized by means of contracts. Such contracts initiate changes t
o the organization's business model. Contracts are monitored in order
to enable adequate supervision and control to be exercised. A business
model enables users to seek the organization's goals via a number of
functions, such as policy making and plan making. An organizational in
terface controls when collaboration takes place (via argumentation, co
ntracting, or other communicative acts). Senior managers spend most of
their time collaborating on a large number of unscheduled tasks, and
so a collaboration context model provides graceful engagement and dise
ngagement using information about sender, receiver, message and task.
