EVMS Guideline 1 Design Considerations - Defining Authorized Work

ANSI Standard 748 Guideline 1 requires defining of authorized program work elements. This defining process typically involves use of a Work Breakdown Structure (WBS) that is logically developed to enhance organizational management and control of all authorized, product-oriented work scope. The WBS is used as a framework for performance measurement and project management and is a single-source reference for communication, statusing and reporting.

In developing its Guideline 1 system description document, the organization should author procedures ensuring:

1. Accuracy and 100% applicability of a contract SOW to contract Work Scope


2. Only one CWBS is used for a project


3. All SOW project work is included in a CWBS


4. A CWBS containing:
   
   
   • Project line items and end items
   
   
   • All elements specified for external reporting
   
   
   • Elements to be subcontracted, with identification of subcontractors
   
   
   • Control account levels (minimum)
   
   
   • All revisions for authorized changes and modifications
   
   


5. Capability of CWBS to evolve to fit changes in project requirements


6. Reconciliation of the WBS with the SOW (typically by means of a WBS Dictionary)


7. If used, WBS Dictionary accuracy
