    BUSINESS PURPOSE

    The purpose of this activity is to determine if the system operates according to specifications.  

    OVERVIEW

    In preparation for the audit, Systems Engineering obtains from the Technical Library the following documentation:

    1. System Study and Evaluation Report (from Phase 1).

    2. System Design Manual (from Phase 2).

    3. Sub-System Design Manuals (from the various Phase 3's).

    The audit and survey will not require the technical documentation for procedures and programs. Systems Engineering reviews the system documentation in detail to assure complete understanding. It will be the objective of Systems Engineering during the survey to verify all design considerations are operative and the information requirements are being satisfied. Any difference will be noted and accounted for during the survey.

    A system audit and survey is analogous to Phase 1, Activity B, "Current Systems Analysis." The difference is that Systems Engineering is checking actual operations against the documentation, as opposed to documenting the current system. A review of Phase 1/B would be helpful for Systems Engineering before conducting the survey.

    Systems Engineering prepares a Detail estimate and schedule for the phase. Management of the operating departments are advised in advance of the survey and its purpose. Systems Engineering conducts the interviews initially with management, and, with management's cooperation, departmental personnel. Under no circumstances should Systems Engineering mistakenly give the impression that this review is an audit of the department's performance. If any misunderstandings should arise, they are to be resolved immediately. During the interviews, Systems Engineering encourages constructive suggestions and discusses problem areas with operating personnel.

    As a result of this activity, Systems Engineering has conducted a complete system survey.  

    STEPS IN EXECUTION

    1. Systems Engineering collects and studies all pertinent documentation from the Technical Library on the system, including the Phase 1 "System Study and Evaluation Report," Phase 2 "System Design Manual," and Phase 3 "Sub-System Design Manual."

    2. Systems Engineering prepares a Detail estimate and schedule for the activities of Phase 9 (A and B). This estimate and schedule is reviewed with Project Management for approval.

    3. Systems Engineering prepares a survey outline and schedule to study the system.

    4. Systems Engineering conducts the survey and studies the system. Discrepancies between the documentation and the system are noted.
