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.

7
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.
• Organizations were automating their accounting
  systems using batch processing concepts
  application programmers primarily used Fortran
  and COBOL.

1960s
8
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).
• 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 (4GLs).

1980s
9
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 4GLs,
  Java, Visual Basic, IDE Tools and Web-enabled
  Tools

10
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, task-sourcing,
  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!!

12
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.
