MIL-HDBK-502: ACQUISITIONALOGISTICSEstimates of manpower and personnel requirements for new systems arereported at each milestone decision point in the defense systems acquisitionprocess. These requirements provide important input to force structureplans, forecasts, and cost estimates, and help to formulate more costeffective alternatives.4.3.3 Systems Engineering ApplicationThe level of systems engineering activity needed for a total system dependsupon the current stage of design development of its hardware, software,and support. The more design development there is to do, the moresystems engineering analysis will have to be performed. As the state of thedesign evolves, the types and depth of the analyses will also change asprogram objectives are refined.The general discussion of systems engineering provided here addresses thefull design development cycle. But for most defense systems requirements,there are real opportunities to reduce time, costs, and risk associated withany new design activity. These opportunities lie in making the greatest useof available designs for product hardware, for software, and for logisticsupport resources and services.The level of design development required diminishes with the increased useof existing designs in a total system. Certainly the need for many of thesupportability-related analyses is reduced in scope and depth, or altogethereliminated once a design alternative is selected. This reductiondemonstrates proper tailoring of the systems engineering process based onthe changing needs of the program. However, use of the systemsengineering process approach is equally crucial for modifications orcommercial and nondevelopmental item acquisitions—perhaps even moreso. In development programs there is usually time to correct mistakes ordeficiencies, but existing design characteristics are relatively fixed(significant change may be costly or impossible). So selecting an existingdesign alternative for the total system is important. Deficiencies in aselected design have to be compensated for through other design elementsof the total system, which diminishes the total system overall. Only anintegrated systems engineering approach fosters the essential interactionsbetween the related design activities so that imbalances are identified andaddressed.Determining the optimal approach for a total system’s design is a programmanagement decision. All of a program’s technical activities, of which thesystem engineering activities are a part, are intended to support andfacilitate sound program management decisions. These decisions determinethe next set of activities, which in turn lead to the next set in a constantlyevolving set of issues, analysis requirements, and decisions. The acquisitionstrategy, which is developed in consonance with the policies and4-17
MIL-HDBK-502: ACQUISITIONALOGISTICSprocedures of the defense systems acquisition process, serves as a plan forthe management and execution of an acquisition program. Figure 4-4identifies systems engineering principles.SYSTEMS ENGINEERING PRINCIPLES• Know the problem, the customer, and the consumer. Become thecustomer/consumer advocate/surrogate throughout development and infielding the solution; state the problem in independent terms.• Use effectiveness criteria based on needs to make decisions. Selectcriteria that are measurable (objective and quantifiable).• Establish and manage requirements. Ensure the customer and consumerunderstand and accept the requirements.• Identify and assess alternatives so as to converge on a solution. Use asystematic architecture/design method.• Verify and validate requirements and solution performance. Qualitymust be designed in; know the expected results before testing.• Maintain the integrity of the system. Maintain a systems engineeringpresence throughout the program.• Use an articulated and documented process. Use readily availableautomated tools wherever appropriate.4.4 ADDITIONAL INFORMATIONFigure 4-4.
