Chapter 1
Product
Software Engineering

The technology encompasses a process, a set of
methods, and an array of tools that we call
software engineering.
Roles of Software


A Product
The vehicle for delivering a product, such as
Control computer (OS)
 Communication
 Tools

Software delivers “information”
Questions from an Industry
Perspective




Why does it take so long to get software finished?
Why are development costs so high?
Why can’t we find all the errors before we give
the software to customers?
Why do we continue to have difficulty in
measuring progress as software being developed?
An Aging Software Plant



Software, produced over 20 years ago and
modified over 40 times, was barely maintainable.
No one could understand the internal structure
of old programs.
Embedded system (traffic, power plants,
factories) was unable to removed or replaced
despite malfunctions.
Software Competitiveness



Cost
Timeliness
Quality  Why India?
What is Software?



Instructions (computer programs) that when
executed provide desired function and
performance.
Data structures that enable the programs to
adequately manipulate information, and
Documents that describe the operation and use
of programs.
Software Characteristics
1.
2.
3.
Software is developed or engineered, it is not
manufactured in the classical sense.
Software does not “wear out”.
Although the industry is moving toward
component-based assembly, most software
continues to be custom built.
Wear vs. Deterioration
Software Applications

Information content refers to the meaning and
form of incoming and outgoing information.

For example, use highly structured input data (a
database) and produce formatted reports.
Software Applications

System Software: a collection of programs
written to service other programs.
Compilers, editors, and file management utilities.
 Operating system components, drivers,
telecommunications processors.

Software Applications

Real-Time Software: Software that
monitors/analyzes/control real world events as
they occur. Elements include:
Data gathering components
 Analysis component
 Control/output component
 Monitoring component

Software Applications

Business Software:

Payroll
Accounts receivable/payable
 Inventory

MIS
Facilitate business operations or management decision
making
 Interactive client/server computing (point-of-sale
transaction processing

Software Applications

Engineering and Scientific Software:
CAD
 System simulation
 Interactive applications


Embedded Software:

Embedded software resided in ROM
Software Applications



Personal Computer Software
Web-based Software
AI Software:
Expert Systems
 Knowledge-base Systems
 Pattern recognition (image and voice)
 Artificial neural networks

Software Myths



Management Myths
Customer Myths
Practitioner’s Myths
Software
In brief, software is composed of
 Programs
 Data
 Documents
The intent of software engineering is to provide a
framework for building software with higher
quality.
The Cost of Change
Software Poses Challenges
How do we ensure the quality of the software that
we produce?
How do we meet growing demand and still
maintain budget control?
How do we upgrade an aging "software plant?"
How do we avoid disastrous time delays?
How do we successfully institute new software
technologies?
