Introduction
Introduction to Information System
to Information System
• Information technology: the hardware and software a business uses
to achieve objectives.
• Information system: interrelated components that manage information
to:
• Support decision making and control.
• Help with analysis, visualization, and product creation.
• Data: streams of raw facts.
• Information: data shaped into meaningful, useful form.
The role of information systems in
solving administrative problems
• Activities in an information system that produce information:
• Input
• Processing
• Output
• Feedback
• Sharp distinction between computer and computer program vs
information system
What Is an Information System?

Functions of an Information System
Functions of an Information System
An information system contains information about an
organization and its surrounding environment. Three
basic activities—input, processing, and output—
produce the information organizations need. Feedback
is output returned to appropriate people or activities in
the organization to evaluate and refine the input.
Environmental actors, such as customers, suppliers,
competitors, stockholders, and regulatory agencies,
interact with the organization and its information
systems.
• Few business problems are simple or straightforward.
• Most business problems involve a number of major factors that
can fall into three main categories:
• Organization
• Technology
• People
The Problem-Solving Approach

• Problem solving: four-step process
1. Problem identification
2. Solution design
3. Choice
4. Implementation

During implementation and thereafter, the outcome
must be continually measured and the information
about how well the solution is working is fed back
to the problem solvers. In this way, the
identification of the problem can change over time,
solutions can be changed, and new choices made,
all based on experience.
1. Problem identification includes:
• Agreement that problem exists
• Definition of problem
• Causes of problem
• What can be done given resources of firm

Typical technology problems
• Insufficient or aging hardware
• Outdated software
• Insufficient database capacity
• Insufficient telecommunications capacity
• Incompatibility of old systems with new
technology
• Rapid technological change

2. Solution design
• Often many possible solutions
• Consider as many as possible to understand
range of solutions
3. Choice: Factors include
• Cost
• Feasibility given resources and skills
• Length of time needed to implement solution

4. Implementation
• Building or purchasing solution
• Testing solution, employee training
• Change management
• Measurement of outcomes
• Feedback, evaluation of solution
• Problem solving is a continuous process, not a
single event
• Sometimes chosen solution doesn’t work or needs
adjustment
A Model of the Problem-Solving Process
A Model of the Problem-Solving Process
• When firms cannot achieve business objectives these objectives
become challenges.
• Information systems often present solutions, partially or fully, to
these challenges.
• Success in today’s job market requires a broad set of skills.
• Job candidates must have problem-solving skills as well as
technical skills so that they can complete specific tasks.
