INFORMATION SYSTEMS ANALYSIS

The '90s have been a decade in which information
technology has become a major strategic weapon for
organizational supremacy in an ever increasing global
economy!

The late ’90s has seen a “mad rush” to the internet!!!

Since the early 1950s computer-based information
systems (IS) and information technology (IT) have
become increasingly more important to organizations
with each new decade.
1950s

Organizations were wondering if the computer was for
real (kind of like they did in the late '70s and early '80s
with the PC); only the very large organizations could
afford one; application programmers used machine
language and assembly language.
1960s

Organizations were automating their accounting
systems using batch processing concepts; application
programmers primarily used Fortran and COBOL.
1970s

Organizations invested in "on-line" terminals and
databases; the operational level data processing was
automated; application programmers used COBOL
and database management systems (DBMS).
1980s

Organizations addressed the automation of the tactical
and strategic level needs; automation support for
systems development emerges in the form of CASE
technology and code and application generators;
application programmers primarily used COBOL and
4th generation languages (4GL’s).
1990s

Organizations are seeking out ways to use
information to gain competitive advantage

The WEB has become the dominant
computing platform; Java is born mid-1995!

Computer programming is becoming more
visual and object-oriented

Application programmers are primarily using
object-oriented (OO) languages: COBOL, C++
4GL’s, Java, Visual Basic, IDE Tools and
Web-enabled Tools
1990s



Information systems are highly integrated
with data communications for global
connectivity - The Web!
Legacy systems must coexist with newer
technologies and strategies
IDEs, reuse, reverse engineering, tasksourcing, out-sourcing, TQM/software quality,
OO, client-server, Malcomb Baldridge Award,
Internet/Intranet/Extranet systems
development, Java and multi-media (voice
and video) are in vogue (hot topics)
INFORMATION SYSTEMS ANALYSIS

THE DEMANDS OF TODAY'S INFORMATION SYSTEMS
USERS ARE GREATER THAN THEY HAVE EVER BEEN!

CORPORATE OFFICERS SHOULD DEMAND THAT
INFORMATION SYSTEMS BE DEVELOPED IN
ACCORDANCE WITH THE CORPORATE STRATEGIC
PLAN!

CORPORATIONS SHOULD NOT TOLERATE
INFORMATION SYSTEMS DEVELOPMENT THAT IS
OVER BUDGET AND LATE!
THAT’ S THE WAY IT SHOULD BE!!
GOAL FOR THE COURSE
To effectively communicate information
systems analysis concepts, principles,
techniques, tools, and methodologies to each
student so that he/she can demonstrate his/her
own personal understanding and application of
this body of knowledge.
NOTES: 1) Your attitude, NOT your aptitude will be your strongest
asset for success in this course!!
2) My personal commitment to you is to be the best
instructor of this topic that I can possibly be.
