Entity & Process
Value is used and created by business processes. This is a pattern typical of many process based systems, and helps to partition the aspects of an entity amongst different areas of interest. The concept of an organization role is used both to partition a process for workflow and security purposes, and to partition an entity for modeling purposes. Note that a process may interact with more than one entity value, some typically being preconditions or constraints (input values), others being objectives or goals (output values).
