  9. Reqmt. For Risk Management • DoD 5000.2–R: Systems Engineering process shall • Transform reqmts. into an integrated system design solution • Ensure integration of interfaces for all system elements • Characterize and manage technical risks • Apply engineering principles to manage force protection risks

  10. Objective of Risk Management in Systems Engineering • Reduce all risks to acceptable levels • What risk is/isn’t • Inherent in all activities • A potential event • Not a problem - a problem is a consequence that has occurred • Can be an opportunity • Cannot be changed by force of thought – hope, ignoring, or mandate

  11. Prime Risk Characteristics • Probability of Occurrence • Consequence of Occurrence • Uncertainty results when probability not known, therefore risk undefined • Examples • Uncertainty • Where probability within known interval

  12. Root Causes of Risk • Internal to design • Technical issues • Manage with design reviews, risk assessments • External from environment • Multiple sources • Manage with requirements & constraints • Integrating design into environment • Easy to lose sight of details – why?

  13. Which Proposal Used RM?

  14. How the SE Process Supports Risk Management

  15. SE Process • A top-down comprehensive, iterative and recursive problem solving process, applied sequentially through all stages of development, that is used to: • Transforms needs and requirements into a set of system product and process descriptions (adding value and more detail with each level of development). • Generates information for decision makers • Provides input for the next level of developments.

  16. System Analysis & Control • Tools & methods for balancing SE Process • When does this end?

  17. Control Mechanisms for RM • Balancing techniques and tools • Track decisions and requirements • Maintain technical baselines • Manage interfaces • Manage risks • Track cost and schedule • Track technical performance • Verify requirements are met • Review/audit the progress

  18. Specifications • Documents what the system needs to do

  19. Performance Requirements • Detail why the system is needed • Three parts • Function • Performance level • Verification means • How do good requirements help identify probabilities and consequences?

  20. SE Requirements • Desired attributes • Understandable • Unambiguous • Comprehensive • Complete • Concise • Achievable • Verifiable • Must be measurable – why?

  21. SE Requirements • Words that Don’t Provide Measurable Requirements Criteria • Fast • Should • May • Extremely • Under Most Conditions • As Appropriate • User Friendly • Should Fail Gracefully

  22. Use Requirements to Id Risk • Functional view – what • Physical view – how • Tailoring – validity of process • Constraints

  23. Decomposition & Integration • Design is top-down, verification is bottom-up • How helps/hurts in risk identification?

  24. Requirements Verification • Choice of verification methods is a potential risk – how? • If inappropriate may get inaccurate results • Expect verification methods to change over design process • Need a consistent measure • Impact of deviations and waivers on risk

  25. Relating Design to WBS • Reqmts allocation - CI numbers match WBS • Why assess risks by WBS?

  26. Basic Purposes of WBS • Organizational – structure for program management • Business – budget and cost tracking structure • Technical – structure for • Identifying products, processes, dataEnabling configuration management • Developing work packages, e.g. materials acq. • Organizing technical reviews – performance measures, status reports • Addressing risk management

  27. WBS Structure • Accommodates organizational, business & technical needs • Specifications conform to WBS • May contain recurring & nonrecurring effort • Functional organization elements (engr, quality) are not WBS elements

  28. Guidance from Mil-Hnbk-881

  29. WBS Exercise • Background: You have recently been assigned to the IPD Team for the Peace Whey program. Peace Whey is a recently approved FMS program which will provide 20 F-16Cs to the Kurdish Air Force (KAF). The specifications for the Kurdish F-16s call for them to be equipped with the Airborne Jamming System (AJS), an electronic warfare system. Your position will be as AJS team leader responsible for the oversight of design and testing of the AJS system, for its integration into the Peace Whey aircraft, and for the AJS lab and flight testing verification. In addition, you must act as the interface between the AJS team and the other teams making up the IPD Team for the Peace Whey program, making certain that the program office is supported in its overall coordination and management tasks.

  30. WBS Exercise (con’t) Exercise: Referring to the Statement of Customer Requirements for AJS (Part 1) which you have been provided, develop a Work Breakdown Structure (WBS) for the AJS development and production task as a part of the overall air vehicle development task.

  31. AJS Statement of Customer Requirements Customer: Kurdish Fighter Program (Peace Whey) Operational Need: Fighter aircraft operating in a hostile environment require extensive electronic countermeasures (ECM) to defeat air-launched and ground-launched threats to the survivability of the aircraft. These ECM systems must be capable of generating and broadcasting radio frequency (RF) energy at sufficient power levels and in appropriate patterns to defeat any threat encountered by the aircraft. Description: The AJS shall be capable of installation on a lightweight, high-speed, multi-role fighter and shall be supportable in primitive forward operating bases. The system shall be capable of transmitting radio frequency signal in the microwave frequency range at sufficient power levels and in patterns capable of successfully jamming all identified threats at the required operational range.

  32. AJS Statement of Customer Requirements (Cont.) • The AJS system shall consist of the following major components: • 1. Core Avionics: Shall consist of the jammer, the radar warning receiver, and the OFP software. Shall be capable of generating the required RF signal in the microwave band at required power levels and of detecting radar emissions from the threat set at the required ranges. • 2. RF Switch H/I/J Band: Shall control selection of broadcast frequency bands as required. • 3. Fire Control Radar Notch Filter: Shall prevent interference of the Fire Control Radar (FCR) by the AJS system. • 4. Forward Transmit Antenna • 5. Aft Transmit Antenna and Raydome • 6. WRD-650D24 Waveguide • 7. Coaxial Cable

  33. AJS Statement of Customer Requirements (Cont.) • Schedule: • 1.
