Management information system introduction

MIS.

2. 1-2
• MIS—management information systems—is the
development and use of information systems
that help businesses achieve their goals and
objectives
• Three key elements:
• Components of information systems
• Development and use of information systems
• Achieving business goals and objectives
Management Information
System

3. 1-3
• Hardware – desktops, laptops, PDAs
• Software – operating systems, application programs
• Data – facts and figures entered into computers
• Procedures – how the other four components are used
• People – users, technologists, IS support
Information Systems components

4. 1-4
• You should take an active role in specifying
requirements and helping manage development
projects since you are the one who’ll be using the
system to do your job.
• Your responsibilities also include using information
systems responsibly and protecting the system and its
data.

How Can You Use the Five-
Component Framework?
• You can understand and evaluate new
information systems by evaluating and asking
questions about each component separately
and then as a whole system.
• The five components can also be evaluated
based on the order of difficulty and disruption –
hardware is the easiest part while people are
the most difficult.

What is Information?
• We know what an information system is – an assembly of
hardware, software, data, procedures, and people that interact
to produce information. But what is information?
• Definitions vary. Information is:
• Knowledge derived from data.
• Data presented in a meaningful context.
• Data processed by summing, ordering, averaging, grouping,
comparing, or other similar operations.
• A difference that makes a difference.
• All of these definitions will do, choose the definition that works
best for the situation – remember the important point is to
discriminate between data and information.

7. What is Information?
• Information is Subjective
• Information in one person’s context is just a data point
in another person’s context since what may be
important to you may not hold the same level of
importance to someone else.
• Context changes occur in information systems when
the output of one system feeds a second system. Data
in a manufacturing system may be very important to
that system. When it’s combined with data from other
systems, it may lose its prominence in the larger
context.

Characteristics of Information
• Good information must be
• Accurate – entering incorrect sales data creates false information.
• Timely – knowing that production doesn’t have enough raw
materials for next week’s schedule won’t be useful information
three weeks from now.
• Relevant – if your boss needs to know how many shipments were
late last month, you shouldn’t give him a list of all items that
shipped.
• Just barely sufficient – if your boss wants to know how to send an
email, you shouldn’t teach her how to build a computer.
• Worth its cost – is it cost worthy to map out the entire U.S. if you
only need one state?

Difference Between Information Technology and
Information Systems?
Because many people confuse the two terms, compare
what each one consists of and how the two differ.
Information technology drives the development of new
information systems.
• Information Systems include
five components
• Hardware
• Software
• Data
• Procedures
• People
