CHAPTER 13
1. How does building new systems produce organizational change?
• Describe each of the four kinds of organizational change that can be promoted with information technology.
1）Automation: improve efficiency and make manual steps not required
2）Rationalization: Streamline standard operating procedures
3）Business process reengineering: Analyze, simplify, and redesign business processes
4）Paradigm shifts: Rethink the nature of the business and the nature of organization.
• Define business process management and describe the steps required to carry it out.
Business process management: use various tools and methodologies to analyze existing processes, design new process, and optimize those processes and it can never be over for the condition is always changing.
The steps are as follows,
1) Identify processes for change: decide what business processes are most important and how to improve them
2) Analyze existing processes: existing processes should be modified by noting inputs, outputs, sequence and resources.
3) Design the new process: based on the existing process, the new process must show how much it reduces time and cost.
4) Implement the new process: when the new process is modeled, it must be translated into a new set of procedures and rules.
5) Continuous measurement: since processes may deteriorate over times, it needs to be measured continually.
• Explain how information systems support process changes that promote 1) quality in an organization.
2) Make the products or processes simple
3) Improve the existing business processes based on customer demands.
4) Shorten cycle time.
5) Improve quality and precision of design and production
2. What are the core activities in the systems development process?
• Distinguish between systems analysis and systems design. Describe the activities for each.
1) Systems analysis: the analysis of a problem that a firm tries to solve with an information system.
Composition of systems analysis:
