    BUSINESS PURPOSE

    The purpose of this activity is to define and/or modify as required the logical model of the enterprise, in part or in full. Depending on the scope of the project, this activity may be used to define or modify the entire enterprise or for a single area within it (e.g., income, administer resources, outcome).  

    OVERVIEW

    This activity represents the steps required to perform "Enterprise Decomposition," the EEM technique for defining the logical structure of the enterprise.

    As was defined in the Methodology Overview, an enterprise has three basic areas of responsibility: to produce/generate income, to administer resources, and to produce products and/or services. These three areas represent a high level description of the operation of the enterprise. Each can be decomposed into more refined levels of detail. This is based on the concept that there are Policy, Control and Operational levels of responsibilities in an enterprise.

    Operational level responsibilities are used to execute, operate, conduct or perform routine duties; (e.g., Assemble Product, Inventory Parts, Contact Customer, etc.)

    Control level responsibilities are used to regulate operations and implement policy decisions; (e.g., Monitor Product Assembly, Report Project Status, Control Sales Representatives, Control Accounts Receivables, etc.).

    Policy level responsibilities are used to establish enterprise decisions and objectives; (e.g., Establish Marketing Objectives, Plan Budget, etc.).

    Responsibilities are written using verbs and nouns to identify the "objects" involved. Each function must be associated with at least one "object."

    The responsibilities are grouped together into a single function based on common missions and types of responsibilities (P/C/O). A written description of a function consists of a SCOPE denoting the purpose and range of the responsibilities, and a listing of each responsibility.

    STRUCTURING FUNCTIONS

    Functions are organized into a three tiered hierarchical structure denoting the basic levels of responsibilities in an enterprise (policy, control and operational). The original high-level functions are used to represent the policy level. Each policy level function is then divided into one or more subordinate control functions, which is divided into one or more operational functions.

    The criteria for structuring functions is based on common missions (income, resources, outcome), type of function (P/C/O) and the affected objects.

    As an example, consider this list of functions:

    FUNCTION MISSION TYPE OBJECT -------- ------- ---- ------ A INCOME CONTROL CUSTOMER B INCOME OPERATIONAL CUSTOMER C INCOME CONTROL PRODUCT D INCOME OPERATIONAL PRODUCT E INCOME POLICY CUSTOMER AND PRODUCT F OUTCOME CONTROL PRODUCT G OUTCOME OPERATIONAL PRODUCT H OUTCOME POLICY PRODUCT & SERVICE I OUTCOME CONTROL SERVICE J OUTCOME OPERATIONAL SERVICE

    These functions can be organized into a three level hierarchical structure like this:

    -------------- -------------- | FUNCTION E | | FUNCTION H | | (MARKETING)| | (MANUFACT) | -------------- -------------- | | ---------------- ---------------- | | | | -------------- -------------- -------------- -------------- | FUNCTION A | | FUNCTION C | | FUNCTION F | | FUNCTION I | | (SALES MGT)| | (PROD-PLAN)| | (PROD-CNTL)| | (CUST-SVC) | -------------- -------------- -------------- -------------- | | | | | | | | -------------- -------------- -------------- -------------- | FUNCTION B | | FUNCTION D | | FUNCTION G | | FUNCTION J | | (SALES) | | (R & D) | | (ASSEMBLY) | | (SERVICE) | -------------- -------------- -------------- --------------

    Obviously this is a simple example; there could be many functions at either the operational or control levels. However, it does show how an area of responsibility can be decomposed into smaller descriptions. The two policy functions are connected via their relationship to the enterprise level which resides over the top of both functions.

    The benefits from structuring the enterprise in this manner is that it provides a guideline for establishing a chart of accounts for accounting purposes and can also provide the means to establish "profit centers" in the enterprise.

    Each function is then cross-referenced to external enterprises that immediately affect them.  

    STEPS IN EXECUTION

    1. Enterprise Engineering groups responsibilities together into functions based on commonality. A formal Function Profile of each function is prepared.

    2. Functions are structured by Enterprise Engineering into a three level hierarchy denoting policy, control and operational responsibilities. A Function Chart is prepared which reflects this structure.

    3. The Function Chart and Function Profiles are reviewed with Quality Assurance to assure they have been prepared according to standards. Adjustments are made as required.

    4. Enterprise Engineering reviews the documentation with User Management and makes changes as required.
