13 DoD Acquisition Environment
Discuss McNamara Era DoD Acquisition Environment

14 Pre-1961 Situation Analyzed
Twelve major systems were studied (ATLAS, JUPITER, POLARIS, BOMARC I, NIKE AJAX, NIKE HERCULES, 8-58, F-105, F4-H, T ALOS, NIKE-ZUES, AND SPARROW III). Conclusions with regard to the development of these programs were: “On the average, quality outcomes in our sample tended to exceed original predictions. This performance was achieved, however, at the expense of: Development time - Actual development time averaged 36% greater than predictions, Costs - An average increase of over 200% and as much as seven times original estimates.”

15 What Did SEC DEF Do About This Situation?
Made costs equal in importance to performance and lead-time in the normal program, as a matter of policy. Made elimination of “gold plating” a policy goal. Made an increase in competition a policy goal. Made reduction in cost-type contracts, particularly Cost Plus Fixed Fee, a policy goal. Established a concept formulation and contract definition procedure. Established a broad range of system analysis studies to aid the decision making process so that life cycle costing and long range force structure planning became an intimate and significant feature.

19 Program Objectives and Thresholds
Beginning at the inception of a new acquisition program, the PM shall propose objectives and thresholds for cost, schedule, and performance, that will result in systems that are affordable, timely, operationally effective, operationally suitable, and survivable. The PM shall refine these objectives and thresholds as the program matures, consistent with operational requirements.

20 Program Goals shall be Identified as Objectives and Thresholds
Every acquisition program shall establish program goals – thresholds and objectives for the minimum number of cost, schedule, and performance parameters that describe the program over its life cycle.

21 Definition – Objective*
The objective value is the value desired by the user, and the value the Program Manager tries to obtain. The objective value represents an incremental, operationally meaningful, time-critical, and cost-effective improvement to the threshold value of each program parameter. * Reference – DoD R, Chapter 1

22 Definition – Threshold*
For performance, threshold shall mean the minimum acceptable value that, in the user’s judgment, is necessary to satisfy the need. For schedule and cost, threshold shall mean the maximum allowable value. If performance threshold values are not achieved, program performance may be seriously degraded, and the utility of the system may become questionable. If schedule threshold values are not achieved, the program may no longer be timely. If cost threshold values are not achieved, the program may be too costly, and the affordability of the system may become questionable. * Reference – DoD R, Chapter 1

23 Policy on Cost-Performance Trade-Offs*
Cost, schedule, and performance may be traded-off within the “trade space” between the objective and the threshold without obtaining Milestone Decision Authority approval. Trade-offs outside the trade space shall require approval of both the Milestone Decision Authority and the Operational Requirements Document approval authority. Validated key performance parameters (KPPs) may not be traded-off without Requirements Authority approval. * Reference – DoD R, Chapter 1

53 EXERCISE #1 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. 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.

54 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.

55 AJS Statement of Customer Requirements (Cont.)
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. 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

56 AJS Statement of Customer Requirements (Cont.)
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. Customer Priorities: 1. Power Transmitted. 2. Weight 3. First production delivery. 4. Cost not to exceed $125,000/unit (for 20 units).

57 See MIL-HDBK-881

58 Cost, Schedule, and Performance Risk Management
The program manager shall establish a risk management program for each acquisition program to identify and control performance, cost, and schedule risks. The risk management program shall identify and track risk drivers, define risk abatement plans, and provide for continuous risk assessment throughout each acquisition phase to determine how risks have changed. Risk reduction measures shall be included in cost-performance tradeoffs, where applicable. The risk management program shall plan for back-ups in high risk areas and identify design requirements where performance increase is small relative to cost, schedule, and performance risk.

59 Cost as an Independent Variable (CAIV)
The acquisition strategy shall address methodologies to acquire and operate affordable DoD Systems by setting aggressive but achievable cost objectives and managing achievement of these objectives. Cost objectives shall be set to balance mission needs with projected out-year resources, taking into account anticipated process improvements in both DoD and defense industries. This concept has become known as “cost as an independent variable,” meaning that cost shall be more of an input, and less of an output, in the process of acquiring DoD systems.

60 Cost/Performance Tradeoffs
Life-cycle cost-performance tradeoffs shall be considered in each phase by a life-cycle cost-performance integrated product team (CPIPT). The organization and activities of the CPIPT is based on the principle that the best time to reduce life-cycle cost is early in the acquisition process and that cost performance tradeoffs analyses shall be conducted before an acquisition approach is finalized.
