SILO PERSPECTIVE VERSES
BUSINESS PROCESS PERSPECTIVE

John Wiley & Sons, Inc. & Dr. Chen, Information Systems – Theory and Practices5
Silo (Functional) Perspective
• The silo perspective views the business as discrete functions (accounting, sales, production, etc.). Figure 5.1 shows a traditional org chart which is how a functional business is organized.
• Each functional area determines its core competencies and focuses on what it does best.
• Advantages:– Allows optimization of expertise.– Group like functions together for learning.
• Disadvantages:– Significant sub-optimization.– Tend to lose sight of overall organizational objectives.

Process Perspective
• Process is defined as an interrelated, sequential set of activities and tasks that turns inputs into outputs, and includes the following: – A beginning and an end
– Inputs and outputs– A set of tasks (subprocesses) that transform the
inputs into outputs– A set of metrics for measuring effectiveness
• Keeps the big picture in view.• Focuses on work being done to create optimal value
for the business.
John Wiley & Sons, Inc. & Dr. Chen, Information Systems – Theory and Practices8
Process Perspective• Examples of business processes include:
– customer order fulfillment– manufacturing, planning and execution– payroll– financial reporting– procurement (see figure 5.2)

Process Perspective
• Advantages:– Helps avoid or reduce duplicate work.– Facilitate cross-functional communication.– Optimize business processes.
• Figure 5.3 shows the cross-functional view of processes as they cross departments (functions).

Process Perspective (continued)
• When managers gain the process perspective they begin to lead their organizations to change.– Question status quo.
– Don’t accept “because we have always done it that way” as an answer to why business is done in a particular way.
– Allows managers to analyze business’s processes in light of larger goals.
• Zara is a good example of a process perspective business (see chapter 2).

THE TOOLS FOR CHANGE
John Wiley & Sons, Inc. & Dr. Chen, Information Systems – Theory and Practices20
Incremental Change
• Total Quality Management (TQM) is a tool for change that uses small incremental changes.
• Personnel often react favorably to TQM.
• Greater personnel control and ownership.
• Change is viewed as less of a threat.
• Six-Sigma is one popular approach to TQM
11
John Wiley & Sons, Inc. & Dr. Chen, Information Systems – Theory and Practices21
Six Sigma• Six Sigma asserts that –
– Continuous efforts to achieve stable and predictable process results are of vital importance to business success.
– Manufacturing and business processes have characteristics that can be measured, analyzed, improved and controlled.
– Achieving sustained quality improvement requires commitment from the entire organization, particularly from top-level management.
• It seeks to eliminate defects from any process.
John Wiley & Sons, Inc. & Dr. Chen, Information Systems – Theory and Practices22
Sigma levels– further information
Short-term sigma levels correspond to the following long-term DPMO values (one-sided):
• One Sigma– 690,000 DPMO = 31% efficiency
• Two Sigma– 308,000 DPMO = 69.2% efficiency
• Three Sigma– 66,800 DPMO = 93.32% efficiency
• Four Sigma– 6,210 DPMO = 99.379% efficiency
• Five Sigma– 230 DPMO = 99.977% efficiency
• Six Sigma– 3.4 DPMO = 99.9997% efficiency
12
John Wiley & Sons, Inc. & Dr. Chen, Information Systems – Theory and Practices23
Six Sigma
• Six Sigma is a business management strategy, originally developed by Motorola (by Bill Smith), that today enjoys widespread application in many sectors of industry.
• Six Sigma seeks to identify and remove the causes of defects and errors in manufacturing and business processes. It uses a set of quality management methods, including statistical methods, and creates a special infrastructure of people within the organization who are experts in these methods.
• Processes that operate with "six sigma quality" over the short term are assumed to produce long-term defect levels below defects per million opportunities (DPMO).3.4

Radical Change & BPR
• Business Process Reengineering (BPR) is a more “radical” change management tool.
• Attain aggressive improvement goals.• Goal is to make a rapid, breakthrough impact on key
metrics.• Figure 5.5 shows the difference over time of the
radical (BPR) and incremental (TQM) approaches to change.
• Greater resistance by personnel.• Use only when major change is needed.

The Process for Radical Redesign
• The different approaches for radical redesign all include:– Begin with a vision of which performance metrics best
reflect the success of overall business strategy.– Make changes to the existing process.– Measure the results using the predetermined metrics.
• Figure 5.6 illustrates a general view of radical design.• Figure 5.7 illustrates a method for redesigning a
business process.• Tool used to understand a business process is a
workflow diagram.

Risks of Radical Redesign
• Research shows some of the common reasons why companies fail to reach their goals:– Lack of senior management support.
– Lack of coherent communications.
– Introducing unnecessary complexity.
– Underestimating the amount of effort needed.
– Combining reengineering with downsizing.
John Wiley & Sons, Inc. & Dr. Chen, Information Systems – Theory and Practices30
AGILITY AND CONSTANTLY REDISGNING PROCESSES
16
John Wiley & Sons, Inc. & Dr. Chen, Information Systems – Theory and Practices31
Agile Processes
• Agile processes are processes that iterate through a constant renewal cycle of design, deliver, evaluate, redesign, and so on.
• Ultimate goal for some are agile processes that reconfigure themselves as they ‘learn.
• For a process to be agile necessitates a high degree of use of IT.
• Processes that run entirely on the Internet are candidates for becoming agile processes.
John Wiley & Sons, Inc. & Dr. Chen, Information Systems – Theory and Practices32
Shared Services
• Horizontal integration - term for looking beyond individual business processes and considering the bigger, cross functional picture of the corporation. – Integrated databases, web 2.0 technologies and services,
and common infrastructure are the tools IT brings to the implementation of horizontal integration.
• Many organizations have restructured their common business processes into a shared services model. – This model consolidates all individuals from all business
units into a single organization, run centrally, and utilized by each business unit.
17
John Wiley & Sons, Inc. & Dr. Chen, Information Systems – Theory and Practices33
Business Process Management (BPM) Systems
John Wiley & Sons, Inc. & Dr. Chen, Information Systems – Theory and Practices34
BPM• In the 1990s, a class of systems emerged to help manage
workflows in the business.
• They primarily helped track document-based processes where people executed the steps of the workflow.
• They go way beyond the document-management capabilities, including features that manage person-to-person process steps, system-to-system steps, and those processes that include a combination. – Systems include process modeling, simulation, code
generation, process execution, monitoring, and integration capabilities for both company-based and web-based systems.
– The tools allow an organization to actively manage and improve its processes from beginning to end.

ENTERPRISE SYSTEMS
19
John Wiley & Sons, Inc. & Dr. Chen, Information Systems – Theory and Practices37
Enterprise Systems
• A set of information systems tools used to enable information flow within and between processes.
• Enterprise systems are comprehensive software packages.
• ERP (Enterprise Resource Planning) software packages are the most frequently discussed type of enterprise system.
• Designed to manage the potentially hundreds of systems throughout a large organization.
• SAP is the most widely used ERP software package.
John Wiley & Sons, Inc. & Dr. Chen, Information Systems – Theory and Practices38
Characteristics of Enterprise Systems
• Integration – seamlessly integrate information flows throughout the company.
• Packages – they are commercial packages purchased from software vendors (like SAP, Oracle, Peoplesoft, etc.).
• Best practices – reflect industry best practices.• Some assembly required – the systems need to be
integrated with the existing hardware, OS’s, databases, and telecommunications.
• Evolving – the systems continue to change to fit the needs of the diverse marketplace.
20
John Wiley & Sons, Inc. & Dr. Chen, Information Systems – Theory and Practices39
Benefits and Disadvantages of Enterprise Systems
• Benefits:– All modules easily communicate together.– Useful tools for centralizing operations and decision
making.– Can reinforce the use of standard procedures.
• Disadvantages:– Implementation is an enormous amount of work.– Most require some level of redesigning business processes.– Hefty price tag (sold as a suite).– They are risky.
John Wiley & Sons, Inc. & Dr. Chen, Information Systems – Theory and Practices40
The Adoption Decision
• Sometimes it is appropriate to let the enterprise system drive business process redesign.– When just starting out.– When organizational processes not relied upon for strategic
advantage.– When current systems are in crisis.
• Sometimes it is inappropriate to let the enterprise system drive business process redesign.– When changing an organizations processes that are relied
upon for strategic advantage.– When the package does not fit the organization.– When there is a lack of top management support.

INTEGRATED SUPPLY CHAINS
John Wiley & Sons, Inc. & Dr. Chen, Information Systems – Theory and Practices42
What is a Supply Chain (network)?
• A supply chain is a network of organizations that are involved, through upstream and downstreamlinkages, in the different processes and activities that produce value in the form of products and servicesdelivered to the ultimate consumer.
• A supply chain has three flows:– Information, – Goods/materials, and – Payment
• Today’s supply chain is a complex web of suppliers, assemblers, logistic firms, sales/marketing channels, and other business partners linked primarily through information networks and contractual relationships.

The Financial and Business Reporting Supply Chain
John Wiley & Sons, Inc. & Dr. Chen, Information Systems – Theory and Practices46
Integrated Supply Chains
• Processes linked across companies.
• Supply chain begins with raw materials and ends with a product/service.
• Globalization of business and ubiquity of communication networks permits use of suppliers from anywhere.
• Requires coordination among partners of the integrated supply chain.
24
John Wiley & Sons, Inc. & Dr. Chen, Information Systems – Theory and Practices47
Integrated Supply Chain (continued)
• Challenges include:– Information integration.– Synchronized planning.– Workflow coordination.
• Leads to new business models.– For example when banks link up to businesses new
financial services are offered such as on-line payments.
– Companies list needs and vendors electronically bid to be the supplier.

FOOD FOR THOUGHT: IS ERP A UNIVERSAL
SOLUTION?: CROSS-CULTURAL
BUSINESS PROCESSES
25
John Wiley & Sons, Inc. & Dr. Chen, Information Systems – Theory and Practices49
Cross-Cultural Business Processes
• Major vendors, SAP and Oracle, show a western bias in reporting best practices.
• Due to problems encountered, businesses in non-western companies/locations are turning to local vendors.
• If the system is based on a cultural model that conflicts with the local customs and which can not easily be accommodated by the ERP it should NOT be implemented.
John Wiley & Sons, Inc. & Dr. Chen, Information Systems – Theory and Practices50
Summary
• IS can enable or impede business change.• You must look at business process to understand
the rule IS plays in business transformation.• TQM or BRP are normally used to make changes
to business processes.• ERP systems can be used to affect organizational
transformation.• Information systems are useful tools to both
enable and manage business transformation.
