4 System Requirements Operational Requirements Maintenance Concept TPMs Performance Based Logistics Goal - Right Asset, Right Place, Right Time
5
5 PBL Performance Based Logistics (also commonly referred to as Performance Based Life Cycle Product Support and PBL) is a performance-based product support strategy for the development and implementation of an integrated, affordable, product support package designed to optimize system readiness and meet the Warfighter’s requirements in terms of performance outcomes for a weapon system through long-term product support arrangements with clear lines of authority and responsibility. DAU
6
6 PBL Lexington Institute paper – Dr. Daniel Goure –Affordable, integrated package based on output measures such as availability –Private sector incentivized Reduce costs Increase availability
7
7 PBL Lexington Institute paper –25 years in commercial business –Power by the hour Guarantee minimum number of flying hours for each engine –Replace faulty engine within specified time period –Also used by Caterpillar, Honeywell, Rolls-Royce, and Allison
8
8 PBL Lexington Institute paper –Performance outcomes Decrease Delivery time Decrease Work-in-progress Reduce Turn-around times Increase Reliability Reduced logistics Increase Availability of systems Reduce overall cost
9
9 PBL Lexington Institute paper –Secret to Success –On time deliveries to the field –Flow of accurate information Anticipate demand Identify and implement positive changes Provide alternative maintenance practices –Incentive to have continuous improvement –Reduces government personnel cost
10
10 PBL Lexington Institute paper –How it works Fixed price for desired outcomes Buy results – Need the right parameters/metrics Provider makes more money when more efficient – self motivated
11
11 PBL DLA PBL briefing –Fixed price “pay for performance” contract motivates vendor to reduce failures & consumption –Long term commitment enables vendor to balance risk vs. investment to attain a return on investments in availability and reliability DLA
12
12 PBL F/A-18 F404 EngineGE –Pre PBL 43 % availability 718 backorders –Post PBL 90% availability 0 backorders Contract value of $641M Cost savings of $90M DLA
13
13 PBL Navy MH-60 Seahawk Helicopter, Sikorsky/Lockheed Martin –1200 airframe and avionics components –530 aircraft –Inventory accuracy of 99.91% –Readiness is 92% from 66% –Backorders from 800 to 0. –Reduced Logistics Response time by 45 days –Invested $140M to increase reliability DLA

15 Requirements Allocation How do you break the requirements down? Negotiate with other IPTs if to tight or to loose Goal - Right Asset, Right Place, Right Time
16
16 Design Review and Evaluation Supportability Review Checklist –Logistics functions adequately defined –Supply chain functions been defined –Systems maintenance concept –Supportability analysis completed Supportability analysis support the maintenance concept Supportability analysis define all logistics requirements. Integrate different models –Specific requirements been defined Goal - Right Asset, Right Place, Right Time
