  • A Systems Perspective of Balanced Scorecard and SCOR Assessment of Supply Chains By Sumanth Pandith Surendra
  • Project Objectives
    • Modeling complexity in the supply chain system.
    • Mapping and analyzing interdependencies among the sub-system’s in a supply chain using Supply Chain Operations Reference-Model (SCOR) model.
    • Applying ISM (Interpretive Structural Modeling) technique for analyzing the complex structure.
    • Supply chain performance management using Balanced Scorecard (BSC) and SCOR models.
    • Integration of BSC and SCOR models for optimizing the performance management.
  • Introduction to Systems Engineering
    • A system is defined as a set of interacting or interdependent entities which forms an integrated whole.
    • A system is complex when it contains complex interdependencies among its entities or sub-systems.
    • Systems engineering is a field which deals to manage these complex interdependencies in a system.
    • The need for systems engineering arose when there is increase in complexity of the system.
  • Introduction to Supply Chain
    • A supply chain is defined as the network of manufacturers, suppliers, distributers, retailers.
    • A supply chain typically involves materials and information flow.
    Source: Wikipedia
  • Supply chain from system’s perspective
    • A supply chain is seen as a system with its sub-systems (entities) and their interactions.
    • The interactions is known as interdependencies.
    • Supply chain is said to be complex if the interdependencies among the sub-systems are complex.
    • The sub-systems in a supply chain could be planning, production and distribution departments.
    • The information flow and the material flow among the sub-systems are the interactions or the interdependencies.
  • A typical supply chain system with interdependencies Sales Production Planning General Ledger Purchasing Customers Vendors Inventory Shop Floor execution A/R A/P
  • Need for a model
    • A system is modeled for analyzing complex interdependencies.
    • Some of process models used in systems engineering for modeling are:
    • Control flow graphs.
    • Functional flow block diagram.
    • Binary decision diagram.
    • IDEF diagrams
    • N2 charts.
  • SCOR Model
    • SCOR (Supply Chain Operations Reference-Model) is a process reference model used for modeling supply chain system.
    • SCOR was first developed by Supply Chain Council (SCC).
    • SCOR is a management tool used for process modeling and performance management.
    • SCOR has 5 distinct processes for supply chain modeling.
    • Plan, Source, Make, Deliver and Return are the 5 sub-systems in a supply chain.
  • SCOR model for a supply chain showing the sub-systems The First level hierarchy of the Supply Chain System with sub systems.
  • MESTT (Meta Data Enabled Systems Thinking Tool) Reports Database yEd Query ISM Graphml Interpreter Input
  • Perform Systems Thinking (Source MESTT Project)
  • Decomposing subsystems into elements Sub systems and its elements as activities as 2nd level hierarchy
  • Modeling the sub systems and system elements.
  • Interpretive Structural Modeling
    • Malone, 1975:
    • ISM “is used here to refer to the systematic application of some elementary notions of graph theory in such a way that theoretical, conceptual, and computational leverage is exploited to efficiently construct a directed graph, or network representation, of the complex pattern of a contextual relationship among a set of elements.”
  • Interpretive Structural Modeling
    • Management and interpretation of input from individuals or groups.
    • Computer-assisted learning process.
    • Network analysis / graph theory
    • Better understanding of direct and indirect relationships among a system’s components
  • Interpretive Structural Modeling (ISM) analysis Circular layout with the most dependent entity in the whole system
  • Hierarchical layout in left to right position
  • Circular layout in single cycle form
  • Circular layout with the centrality measures calculation
  • 1st order Reachability nodes (elements) in the system
  • Implications from the ISM study for the complex system
    • It is evident that by analyzing the interdependencies in the system we can reduce the complexity of the system.
    • MRP is the most dependent entity among the sub systems of Planning, Sourcing, Making & Delivery.
    • Increases the visibility in the supply chain system.
    • Improves communication and co-ordination among the sub systems.
    • Increases responsiveness in the system and feedback loops are managed efficiently.
  • Balanced Scorecard (BSC)
    • BSC is a management tool used for performance management in an organization.
    • BSC develops performance metrics based on four categories in an organization and they are:
    • Customer Perspective.
    • Financial Perspective.
    • Internal business perspective.
    • Innovation and learning perspective
  • Drawbacks of conventional performance management approach
    • Lack of Balanced approach
    • Lack of understanding
    • Lack of distinction of metrics at various organizational levels
    • Lack of formal structure for metrics
  • Performance management for supply chain
    • Gunasekaran et al. (2001) developed metrics three different organizational levels such as strategic tactical and operational levels.
    • Further, categorized into financial and non-financial metrics.
      X Inventory carrying cost     X Information carrying cost   X   Capacity utilization     X Manufacturing cost Operational X   Product development time   X   Forecasting methods   X   Total transportation cost   X   Extent of cooperation to improve quality Tactical X   Customer query time     X Buyer/supplier relationship level   X   Total cycle time   X   Delivery lead time   X   Flexibility to meet particular customer needs     X Rate on return on investment X   Total cash flow time Strategic Non financial Financial Performance metrics Level
  • BSC for supply chain performance management (Source: Gunasekaran et al., 2001)         Supplier rejection rate operational expenses Delivery reliability Supplier cost saving initiatives Delivery performance Supplier relationship level Budget variations Rate of ROI Net Profit vs. Productivity ratio Financial Metrics   Defect free deliveries Delivery quality Responsiveness Delivery reliability Invoicing efficiency Delivery performance Delivery lead time Flexibility Order lead time Products range and services customer perception Customer query time Customer satisfaction metrics

  • SCOR application for Supply Chain performance measurement
    • SCOR is also applied for the performance measurement of the supply chain activities and processes.
    • SCOR model helps to describe the supply chain in five different dimensions such as reliability, responsiveness, flexibility, and cost and asset management efficiency.
    • Using SCOR we can have the structured hierarchy for the performance metrics across the whole supply chain.
    • Decompose the metrics from top which may be called as level 1 metrics to the next level which may be called as level 2 metrics.
  • Performance Attributes and Level 1 Metrics (Scott Stephens Dec 2001) Inventory days of supply asset turns Effectiveness of an organization in managing assets to support demand satisfaction, this includes the management of all assets like fixed and working capital Supply chain asset management efficiency cash to cash cycle time Costs associated with operating the supply chain Supply chain costs a) Supply chain response time b) Production flexibility c) Cost of goods sold d) Total supply chain management costs e) Value added productivity f) Warranty/returns processing costs Agility of a supply chain in responding to marketplace changes to gain or maintain competitive advantage Supply chain flexibility Order fulfillment lead times Velocity at which a supply chain provides products to the customer Supply chain responsiveness a) Delivery performance b) Fill rates c) Perfect order fulfillment Performance of supply chain in delivering right product to the right place at the right time in the right condition in the right quantity with the right documentation to the right customer Supply chain delivery reliability Level 1 metric Performance attribute definition Performance attribute

    • Combining SCOR and BSC the performance metrics can be linked to the individual business processes.
    • Performance metrics in supply chain can be categorized hierarchically so as to track them easily.
    • Performance measures could be carried not only at the organizational level but also at the process level.
    • Track the performance linking with the organizational business processes.
    • We can track the impact of supply chain metrics on the organizational performance.
