- 2. Principles and Learning Objectives • The use of information systems to add value to the organization is strongly influenced by organizational structure, culture, and change – Identify the value-added processes in the supply chain and describe the role of information systems within them – Provide a clear definition of the terms organizational structure, culture, and change and discuss how they affect the implementation of information systems
- 3. Principles and Learning Objectives (continued) • Because information systems are so important, businesses need to be sure that improvements or completely new systems help lower costs, increase profits, improve service, or achieve a competitive advantage – Identify some of the strategies employed to lower costs or improve service – Define the term competitive advantage and discuss how organizations are using information systems to gain such an advantage – Discuss how organizations justify the need for information systems
- 4. Principles and Learning Objectives (continued) • Cooperation between business managers and IS personnel is the key to unlocking the potential of any new or modified system – Define the types of roles, functions, and careers available in information systems
- 5. Why Learn About Information Systems in Organizations? • Information systems (ISs) can cut costs and increase profits • Students in most fields need to know ISs – Management major might be hired to design a system to improve productivity – Biochemistry major might be hired to conduct drug research using computer techniques
- 6. Organizations and Information Systems • Organization: a formal collection of people and other resources established to accomplish a set of goals • An organization is a system - has inputs, processing mechanisms, outputs, and feedback – Inputs to the system: resources such as materials, people, and money – Outputs to the environment: goods or services
- 7. Organizations and Information Systems (continued) Figure 2.1: A General Model of an Organization
- 8. Organizations and Information Systems (continued) • Value chain: series (chain) of activities that includes inbound logistics, warehouse and storage, production, finished product storage, outbound logistics, marketing and sales, and customer service • Upstream management: management of raw materials, inbound logistics, and warehouse and storage facilities • Downstream management: management of finished product storage, outbound logistics, marketing and sales, and customer service
- 9. Organizations and Information Systems (continued) Figure 2.2: The Value Chain of a Manufacturing Company
- 10. Organizational Structures • Organizational structure: organizational subunits and the way they relate to the overall organization • Categories of organizational structure – Traditional – Project – Team – Virtual
- 11. Traditional Organizational Structure • A hierarchical structure • Major department heads report to a president or top-level manager • Managerial pyramid shows the hierarchy of decision making and authority
- 12. Traditional Organizational Structure (continued) Figure 2.4: A simplified model of the organization, showing the managerial pyramid from top-level managers to nonmanagement employees
- 13. Traditional Organizational Structure (continued) Figure 2.5: A Traditional Organizational Structure

- 15. Project and Team Organizational Structures (continued) Figure 2.6: A Project Organizational Structure
- 16. Virtual Organizational Structure and Collaborative Work • Virtual organizational structure – Employs business units in geographically dispersed areas – People may never meet face to face – Allows collaborative work • Managers and employees can effectively work in groups, even those composed of members from around the world
- 17. Organizational Culture and Change • Organizational culture – Major understandings and assumptions – Influences information systems • Organizational change – How organizations plan for, implement, and handle change
- 18. Reengineering and Continuous Improvement • Reengineering – Process redesign – Radical redesign of business processes, organizational structures, information systems, and values of the organization to achieve a breakthrough in business results
- 19. Reengineering and Continuous Improvement (continued) Figure 2.8: Reengineering
- 20. Reengineering and Continuous Improvement (continued) • Continuous improvement – Constantly seeking ways to improve business processes – Benefits • Increased customer loyalty • Reduction in customer dissatisfaction • Reduced opportunity for competitive inroads
- 21. Reengineering and Continuous Improvement (continued) Table 2.2: Comparing Business Process Reengineering and Continuous Improvement

Quality • Quality: ability of a product or service to meet or exceed customer expectations • Techniques used to ensure quality – Total quality management • Involving the entire organization, supply chain, and/or product life cycle • management approach for an organization, centered on quality, based on the participation of all its members and aiming at long-term success through customer satisfaction, and benefits to all members of the organization and to society • widely used in manufacturing, education, call centers, government, and service industries – Six sigma
- 23. Quality – Six sigma • stands for Six Standard Deviations (Sigma is the Greek letter used to represent standard deviation in statistics) from mean. • Six Sigma methodology provides the techniques and tools to improve the capability and reduce the defects in any process. • It was started in Motorola, where millions of parts are made using the same process repeatedly. • Six Sigma methodology improves any existing business process by constantly reviewing and re-tuning the process. • Uses a methodology known as DMAIC (Define opportunities, Measure performance, Analyze opportunity, Improve performance, Control performance)
- 24. Outsourcing, On-Demand Computing, and Downsizing • Outsourcing: contracting with outside professional services • On-demand computing: contracting for computer resources to rapidly respond to an organization’s varying workflow • Downsizing: reducing number of employees
