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

• 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
Supplier
c
Buyer
q
ω, Φ
p
d
Where,
c is the marginal unit cost of supplier
ω is a wholesale unit price charged by the supplier to the buyer
p is the selling price of buyer per unit
Φ is the fraction of supply chain revenue that the buyer keeps and (1- Φ) is the
fraction the supplier earns
q 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
Research 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 and
availability 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 !

Editor's Notes

  • #47 There are four key focuses to On-Demand: 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
  • #48 SOA represents a focused approach towards implementing/developing component oriented solutions – it comes directly from the mandate of MDA/MDD – by representing discrete functions as services and promoting application assembly (versus “development from scratch”), it enables a “building block” approach which encourages the reuse of assets to solve problems as well as enabling the ability to choreograph services to create higher level coarse services. Most importantly, it is founded on open standards to promote interoperable solution design and delivery.
  • #49 These concepts really form the underlying context for SOA – of all of them, service discovery is still in an evolutionary phase although many initiatives around UDDI and other service repository initiatives will provide more context in this area in the near term. Today – service description is largely WSDL-based – service interaction is over an ESB/”smart” messaging framework to enable delivery as well as routing/transform/mediation – service choreography via BPEL – and service creation via MDA/MDD and tools approaches akin to the WebSphere Studio family for application assembly, process choreography, software development management and component definition/discovery.
  • #50 From an IT perspective – moving to the world on On-Demand from an integration perspective comes down to three key focus areas – MDA – To provide a solution framework that maps directly to the business processes and provide abstraction services to build platform independent implementations that can be used to implement integration solutions SOA – To provide a runtime environment that encourages component/service design and construction across distributed environments BPMS – To monitor both IT as well as Business metrics as part of the operational management of the distributed SOA solution foundation
