, Chapter 1: Introduction to Systems Analysis and Design
Chapter 1 – Introduction to Systems Analysis and Design: Chapter 1 provides an
introduction to systems analysis and design by describing the role of information
technology in today’s dynamic business environment.
Questions
1. What is information technology and why is it important to society?
Information technology (IT) refers to the combination of hardware, software, and
services that people use to manage, communicate, and share information. More than
ever, business success depends on information technology. The headlines in Figure 1-1
offer dramatic examples of how information technology issues such as data privacy,
mobile devices, and social media affects our society. We live in a world where we can be
traced, analyzed, and surveilled without our knowledge. This raises many important
questions, such as how to secure personal data while still providing useful functionality
and business value.
2. What are the five main components of an information system?
An information system has five key components, as shown in Figure 1-4: hardware,
software, data, processes, and people.
3. Explain how ridesharing services such as Uber and Lyft are disrupting traditional
taxicab business models.
Business today is being shaped by three major trends: rapidly increasing globalization,
technology integration for seamless information access across a wide variety of devices
such as laptops and smartphones, and the rapid growth of cloud-based computing and
software services. These trends are being driven by the immense power of the Internet.
Ridesharing services such as Uber and Lyft are disrupting traditional taxicab business
models through disintermediation: connecting drivers directly to customers, bypassing
the traditional dispatch service. They are also disrupting the traditional limitation on
who can drive a taxicab (medallion owners) to allow anyone with a car and who wants
to earn some extra money to do so, all via mobile apps and cloud-based technology.
4. Describe the business profile of a home improvement store like Home Depot or
Lowe’s and how it is used.
A business profile is an overview of a company’s mission, functions, organization,
products, services, customers, suppliers, competitors, constraints, and future direction.
Although much of this information is readily available, a systems analyst usually needs
to do additional research and fact-finding to fill out missing or incomplete information.
A business profile is the starting point for the modeling process, and a systems analyst
can describe and simplify an information system by using a set of business models and
business process models. Students should be able to understand the business of home
improvement stores, supply the basic information, and fill in the details.
5. What are the seven types of information systems used in business?
