  1. Aligning Jobs to Organizational Missions Top Down Function Analysis

  2. Purpose • Define TDFA • A foundation for Human Systems Integration • A “glue” that ties systems acquisition elements together • Who can use it? • Human Systems Engineering – to include Training • Systems Engineering • Test and Evaluation • Logistics • Project Management -- audit trail

  3. What is TDFA? • Top Down Function Analysis (TDFA) is a systems engineering approach to the Human Systems Integration (HSI) task of defining and integrating human performance requirements with the system design process. • TDFA helps organizations align jobs to missions

  4. Equips Employees with the Knowledge Skills & Abilities (KSAs) needed to accomplish the mission Training Designs the system to minimize human error and reduce risk of injury System Safety Manpower Environment Addresses all aspects of defining personnel quantitative and qualitative requirements as well as recruiting and retaining those individuals Occupational Health Personnel Retention Ensures that the system is designed with full consideration of the employee’s capabilities and limitations Human Factors Recruiting Ensures that all aspects of the living and working spaces are designed to meet employee’sneeds Personnel Survivability Habitability Provides that the employee will have all personal protection needed What is Human Systems Integration?

  5. Why Do HSI? – DOD Policy DoD INSTR 5000.2 Encl. 7, Para E7.2 “The PM shall take steps to ensure human factors/cognitive engineering is employed during systems engineering over the life cycle … to provide for effective human-machine interfaces and to meet HSI requirements.” DoD INSTR 5000.2, Encl. 7, Para E7.1. “The PM shall have a comprehensive plan for HSI n place early in the acquisition process to optimize total system performance, minimize total ownership costs, and ensure that the system is built to accommodate the characteristics of the user population ….” DoD INSTR 5000.2 Encl. 7, Para E7.6 “The PM shall develop options for individual, collective, and joint training for operators, maintainers and support personnel and, where appropriate, base training decisions on training effectiveness evaluations. The PM shall develop system plans to maximize the use of new learning technology, simulation techniques, embedded training…” Department of Defense (DOD) Policy

  6. Why Do HSI? - Navy Policy SECNAVINST 5000.2C, Para 5.2.3.5.9 Human Systems Integration “The PM shallensure that HSI costs (MPT, HFE, safety, occupational health and habitability) and impacts are adequately considered, weighted, and integrated with other engineering and logistics elements beginning at program initiation.” SECNAVINST 5000.2C Para 4.5.4.2 “Manpower Estimates are required by statute for ACAT I programs…” SECNAVINST 5000.2C Para 5.2.3.5.9.5 “A Navy Training Systems Plan shall be prepared as a program plan…during Phase B, and updated as appropriate throughout the system’s life-cycle.” Department of the Navy Policy

  7. Benefits of TDFA • Provides traceability of human performance and resource requirements to missions (organizational or system) • Influences system or organization design to optimize human performance and resource requirements • Provides means for Human System Integration to participate in the systems engineering process • Insures employee activities are accounted for in mission • Facilitates measurement of HSI impacts of design decisions • Provides comprehensive, validated performance requirements (Mission, Functions, Tasks) that all human analysis disciplines can use for design decision making (HSI, Training, Manpower, Logistics, Publications, etc.)

  11. Training System Design A similar process is used to allocate functional requirements to the Training System. A systems approach is used to identify Training System Alternatives (TSALTs), which result in optimal media selections.
