Value generation from the product is key
Product is used to deliver significant value toProduct is used to deliver significant value to customers.
Loss of availability of product is very EXPENSIVEe g cost of line down for Intel > $100 000/houre.g., cost of line down for Intel > $100,000/hour
Customers define value differently in each caseKLA: value = wafer start throughputCisco: value = connectivityBoeing Defense: value = winning the war
Value varies with customer and with timee.g., plane down during a training exercise vs plane down during a war

A Transition Towards PBL in the US Military
Commercial antecedents to PBL over the last 20 years:
GE Rolls Royce jet engines- GE, Rolls Royce jet engines- Honeywell, Rockwell Collins avionics- Lucas Aerospace landing gear- Garrett auxiliary power units.
“Th f PBL i b i f t t th i di id l“The essence of PBL is buying performance outcomes, not the individual parts and repair actions … Instead of buying set levels of spares, repairs, tools, and data, the new focus is on buying a predetermined level of availability to meet the [buyer’s] objectives.”
Defense Acquisition Guidebook Section 5.3q
“”DoD 5000.1, the Defense Acquisition System, requires program managers to develop and implement PBL strategies that optimize total system availability while minimizing cost … The preferred PBL contracting approach is the use of long-term contracts with incentivescontracting approach is the use of long-term contracts with incentives tied to performance.”
The Undersecretary of Defense, August 16, 2004

Elements of Incentive Contracting
Decentralized decision making:Suppliers invest into spare parts inventories, repair pp p p , p
capacities, product reliability and optimize their supply chains to maximize their profits.The Prime wishes to induce desired actions from suppliersThe Prime wishes to induce desired actions from suppliers
using contracts and wishes to achieve certain product availability for the Customer.
Outcome with respect to both total supply chain costOutcome with respect to both total supply chain cost and up-time performance is uncertain:
Suppliers may act opportunistically and get away with little effort.
Contracting parties are averse to risk.

ConclusionsDelivery of services to enable value creation through product use is a source of revenue growth profit margin customer satisfaction and competitive advantagegrowth, profit margin, customer satisfaction and competitive advantageEffective delivery of such services requires optimized management of service supply chain resourcesCurrent service support management systems often lack the ability to account for incentive effects created by the PBL contractsincentive effects created by the PBL contracts.Our economic models indicate that:
The optimal contract will have a mixture of PBL, cost-sharing and fixed payment terms.O er time the contract ill e ol e from more cost sharing to more performanceOver time, the contract will evolve from more cost-sharing to more performance-based.PBL contract stimulates reliability improvement but works best when supplier owns assets.
There is a lack of empirical evidence on what makes PBL contracts successfulThere is a lack of empirical evidence on what makes PBL contracts successful, companies generally do not keep adequate data.There is an urgent need to apply decision support systems to help with negotiating and executing PBL contracts.Implementation of effective service decision support systems is based on theImplementation of effective service decision support systems is based on the appropriate mix of incentives, optimization models & algorithms, and software systemsSources:M.
