ICOM
ICOM stands for Input, Control, Output, Mechanism. They
are the four types of arrows in an IDEF0 Diagram. In more detail, they
are:
-
Inputs, which are the 'raw material' that
gets transformed during the activity, e.g. a wire coil, outline plans.
-
Controls, which influence or direct how the
process works, e.g. safety standards, customer requirements, project
plans.
-
Mechanisms, which cause the process to
operate, e.g. people, tools, machines.
-
Outputs, which are the result of the
activity and are transmitted to other processes, e.g. cut lengths of
wire, final plans.
