The model is based on two basic characteristics of the organisation. First, organisation can be seen as system of interlocking groups;
and second, the interlocking groups are connected by individuals who
occupy the key positions of dual membership serving as linking pin
between groups. Thus every individual functions as a linking pin for
the organisation units above and below him. He is the group leader
of the lower unit and a group member of the upper unit. In the
linking pin structure a group-to-group, as opposed to traditional
man-to-man, relationship exists.
