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

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
Schedule: 1. Flight Test: The Safety of Flight(SOF) unit for flight test shall be available for installation 26 months after program go-ahead. 2. First Production Delivery: The first production assembly shall be delivered 36 months after program go-ahead. 3. Delivery Rate: Delivery of AJS units shall be at the rate of 2 units per month. 4. Total Quantity: The total quantity of AJS units shall be 20. AJS Statement of Customer Requirements (Cont.) Customer Priorities: 1. Power Transmitted. 2. Weight 3. First production delivery. 4.Cost not to exceed $125,000/unit (for 20 units). Be prepared to report your results to the class. You will have __ minutes for this exercise.

35
Program Schedules Establishes key tasks & results Duration driven “X Months after contract award” Event driven “After CDR complete” When might each be desirable? Risks?
36
Plan & Schedule Terminology Product - Hardware, Software, Facilities, Data, or Materials Event - Decision Point at End of Major Project Activity (EX. - CDR) Accomplishment - Desired Result at Specified Events Criteria - Measure of Meeting Accomplishment Task - Specific Activity to Complete a Criteria
37
SEMS – SE Master Schedule Critical tasks required to complete program milestones Development plans – test, S/W Define interim steps Include verification criteria Define measurable accomplishments 85% complete – good? Test readiness review complete – good?

SEMS, SEDS Exercise Exercise: Develop the portion of a Systems Engineering Master Schedule (SEMS) for the AJS design and development tasks. Assume the system level schedule for Peace Whey includes a SRR, SFR, PDR, CDR, and PRR. Your SEMS should identify a list of AJS program reviews with accomplishment criteria. Part 1: Referring to the system level Peace Whey reviews, identify and list the major reviews which need to be supported by inputs from the AJS design and development tasks. Based upon this list, determine a set or reviews for the AJS development effort required to support the Peace Whey program.
43
SEMS, SEDS Exercise (con’t) Part 2: Identify the accomplishment criteria for one AJS review. Part 3: Develop a System Engineering Detailed Schedule (SEDS) for the AJS design and development task. The AJS Safety of Flight unit must be available in month 26 and first production aircraft in month 36. Hint – Use building block tasks on next page. Be prepared to report your results to the class. You will have 40 minutes for this exercise.
