Research Track 1: Performance Measurement System
• As early as 1985 A T Kearney Consultants have identified a high correlation between superior performance & development /use of sophisticated assessment/measurement capabilities– Firms engaging such systems reported realized
improvements in productivity of 14 to 22 %
Performance Measurement System
What Is Performance Management?
It is a systematic process of Planning work and setting expectations Continually monitoring performance Developing the capacity to perform Periodically rating performance in a summary
fashion Rewarding good performance
Performance Management Cycle
Planning
Rewarding
Rating
Developing
Monitoring
• How well the organization is doing?
• Is the organization meeting its goals?
• Are the customers happy?
• Are the processes in control?
• If and where improvements are necessary?
Issues in performance measurement system
• Measuring the activity (volume) and the SC performance
• Setting goals and comparing the actual situation• Following a plan• Determining the levers that will help achieve
goals and single out the priority action programs• Revealing the degree of flexibility
Objectives of Metrics
Speed, reliability , and simplicity are the main criteria for efficient metrics
• Arranging indicators by priority• Segmenting the metrics• Visualizing the function content• Classifying objectives of the function or team• Selecting indicators that deal with quality• Formatting the metrics effectively
Principles of metrics design
• Independence• Appropriateness• Objectivity• Regularity
• Linkage with other indicators
• Coherence• Simplicity• Cumulative• Realistic
Characteristics of Effective Metrics
• Transparent
• Simple
• self-regulating
• Objective
• Motivating and stimulating to all stakeholders
Performance measurement system (PMS): Desirable Features
• PMS should have multiple criteria• Primary purpose should not be to reward or to punish• Performance-to-schedule measures must use group, not
individual results• Specific goals must be established and reviewed• PM must be understood by those whose performance is
being measured.• PM data must be available for constant review
Performance measurement system (PMS): Desirable Features (contd.)
• Measurements of multiple performance factors occur frequently at each stage in the supply chain
• Time and cost are key measures, but others are used as appropriate to the specific supply chain.
• All measures must relate to the ultimate supply
chain goals.
Quantitatively based performance management
• Cost { total cost, cost/unit, cost/sales, inbound freight, outbound freight, warehouse cost, admn, processing, direct labor etc.}
• Customer service {fill rate, stock-outs, shipping errors, on-time delivery, back-orders, cycle time, customer feedback}
• Productivity {units shipped/employee, units/labour Rs., orders per sales person, etc.}
• Asset Measurement {Inventory turns, Inv. Carry costs, obsolete Inv., ROI etc.}
• Quality {frequency of damage, Rs of damage, Customer returns, Cost of returned goods etc.}
Internal Performance Measurement
• Customer Perception Measurement
• Best Practices benchmarking– World Class Logistic- CLM– Logistics Excellence - Michigan State University
External Performance Measurement
• Framework 1: Function based measurement system• Framework 2: Dimensions based measurement
system• Framework 3: Hierarchical measurement system• Framework 4: Balanced scorecard system• Framework 5:SCOR model
Various frameworks for measurement
• Covers detailed performance measures applicable at different linkages of SC– Marketing, Operations, Finance etc.
Framework 1: Function based measurement system
• Any SC can be measured on three dimensions– SERVICE– ASSETS– SPEED
Framework 2: Dimensions based measurement system
Performance in the functional areas of
• Inbound Logistics
• Operations
• Outbound Logistics
• Marketing
• Service-after-sales
Framework 3:Hierarchical System
quality inventory customer service cost flexibility time, and productivity.
Framework 3:Hierarchical System : Indicators
cost structure of the warehouse operations (handling-in, storage, and handling-out)
total investment total cost of the warehouse total capacity concerning output volume costs warehouse operations per unit volume (m3 , ton) total number of trucks loaded/unloaded per worked time unit labor hours per unit of output volume ( m3, ton) labor costs per unit of output volume (m3, ton) labor costs as percentage of sales
Indicators: Outbound logistics
• Compare each of the metrics and compute the relative weightage for each
• Compare each of the links (inbound logistics, manufacturing etc.) on each of the metrics above and compare relative weightages .
• Compute the aggregate weight for the links.• Rank the links on the basis of weights arrived• Devise an action plan to improve the performance of
weakest/weaker links in the supply chain.• Monitor the performance and repeat steps above on a continual
basis.
Hierarchical System :Procedure
• Various perspectives such as the following should be Balanced!– Financial– Innovation & learning– Customer service– Internal business
Balance scorecard balances and links financial and non-financial indicators, tangible and intangible measures, internal and external aspects, performance drivers and outcomes.
Framework 4: Balanced scorecard
The Supply-Chain Council (SCC) has developed and endorsed the Supply Chain Operations Reference-model (SCOR) as the cross-industry standard for supply chain management
The SCC was organized in 1996 by 69 voluntary member companies and the European Chapter was started in 1998.

Track 2: Revenue Sharing Contracts
• It increases the total supply chain profits• It involves in risk sharing among supply chain
partners• It may be possible with supply chain contracts
that a member achieves more profits than he would do without contracts
• Hence, result in win-win situation for both supplier and his buyer
Objective of Supply Chain Contracts
Revenue sharing model parameters
Supplierc
Buyer
q
ω, Φpd
Where,c is the marginal unit cost of supplierω is a wholesale unit price charged by the supplier to the buyerp is the selling price of buyer per unitΦ is the fraction of supply chain revenue that the buyer keeps and (1- Φ) is the fraction the supplier earnsq is the buyer’s order quantity
• The buyer orders single product• The demand is uncertain with probability
distribution function fd(d) in a single selling period
• The wholesale price is less than the unit marginal cost (ω < c)
Assumptions
• To determine the total supply chain profits• To determine the optimal order quantities
to achieve the optimal supply chain profits
Objectives of revenue sharing contracts
• Most models in the form of network of “newsboy’ problem. There is still room for simple yet imaginative models exploring other inventory concepts
• Time evolution of decisions not fully explored• Use of Game theoretic frameworks: Static games built in s
Markov decision process• More complicated demand and supply structures (correlation,
advance information, disruptions etc.)• Information availability • More sophisticated Supply Chain structures• Implementation issues

Track 3: Management of Information Security in Supply Chains
What is Information Security?
Information“Information is an asset that, like other
important business assets, is essential to an organization's business and consequently needs to be suitably protected”
Information Security“Preservation of confidentiality, integrity andavailability of information”
(Reference: ISO 27000)
Security in Supply Chains
“The application of policies, procedures, and technology to protect supply chain
assets (product, facilities, equipment, information, and personnel) from theft,
damage, or terrorism and to prevent the introduction of unauthorized contraband,
people or weapons of mass destruction into the supply chain”.
– Closs & McGarrell (2004)
There are 2 aspects:• Soft aspect – Intangible vulnerabilities such as information theft• Hard aspect – Tangible vulnerabilities such as physical theft / physical damages / terrorism
Information Security – one of the soft aspects
Hard aspects influence the soft aspects
Why do we need Information Security?
• Measure and mitigate risk related to information assets.
Key motivator –
• Management of business and financial risk
• Reduction of threat to both reputation and customers
.
• Ensure compliance to regulatory/ legislative/ contractual
requirements.
Summary of concerns
• Information leakage & misappropriation in supply chain networks, which can
lead to:
• Demand imperative overriding information imperative
• Product & service deliveries may not be optimal
• Firms may lose their competitive edge
• Vulnerabilities in IT infrastructure may not be adequately controlled
• Information reliability and consequently knowledge generation may be
compromised
• Human security requirements may be overlooked
What is a Process Framework?
• Formal description of processes in a company
• Formally existing / ad-hoc / need to be developed
• KPIs defined to “measure” the process, with industry benchmarks
• Improvements based on the KPI s achieved
• Methodologies – used to actually improve the process
Why do we need a Process Framework?
To enable organizations develop and maintain consistent business practices
• Helps in managing a company's key processes and roles & responsibilities
• Aligns processes and performance improvement with corporate strategy
• Can be implemented at any level of an organization
Research Propositions• Identify weaknesses related to information
security in supply chain processes
• Analyze information security related risks
• Study relationship between supply chain
performance metrics and information security

Track 4: Service Oriented Architecture
Integration ◦ Providing the linkage between people, processes, and data
Open ◦ Supporting a strong commitment to standards for OS, Language and Web
Services/SOA
Virtualized ◦ Providing a flexible Build-time and Runtime environment for developing and
running applications across a highly distributed IT architecture
Autonomic ◦ Self regulating … self healing … self maintaining
46
Four Characteristics of On Demand
47
SOA: Service Oriented Architecture• An approach for building distributed systems that allows tight
correlation between the business model and the IT implementation.
• Characteristics:◦ Represents business function as a service◦ Shifts focus to application assembly rather than implementation
details◦ Allows individual software assets to become building blocks that
can be reused in developing composite applications representing business processes
◦ Leverages open standards to represent software assets
What is a service? A coarse grained, self-contained entity that performs a distinct business
function
What is a service description? A standards based interface definition that is independent of the
underlying implementation
How do services interact? Through loosely-coupled, intermediated connections
How are SOA solutions created and enhanced? Using tools and middleware according to SOA principles
48
SOA Concepts
Build –Model Driven Architecture◦ A style of enterprise application development and integration based on
using automated tools to build system independent models and transform them into efficient implementations1
Run –Service Oriented Architecture◦ An approach for designing and implementing distributed systems that
allows a tight correlation between the business model and the IT implementation
Manage –Business Performance Management◦ An approach to systems management that tightly links IT concerns with
business process concerns
49
Three Key Concepts for the Foundation for On Demand
• How to define service standards?• What is the role of technology in SOA?• How to align business strategy with SOA?• Issues related to flexibility ?
Research Issues
• Supply chain management: an opportunity for seamless integration
• Research issues involving a variety of domains : performance measurement, modeling, security, on-demand business
• Borrowing terminology & frameworks from IT !• Research : interdisciplinary !
