IDS-695 INFORMATION SYSTEMS DEVELOPMENT I WELCOME Ronald Norman, Ph.D., CCP Office: SS-3200 Office Phone: 594-3734 e-mail: [email protected] URL: http://rohan.sdsu.edu/faculty/rnorman Systems Analysis and Design is the process people use to create (automated) information systems Systems Analysis & Design Information System The end result of Systems Analysis is the creation of “blueprints” for the Information System The end result of Systems Design is the creation of the Information System INFORMATION SYSTEMS ANALYSIS • Intuition • Creativity • Spatial imagination • Color • Rhythm • Emotions • Numbers • Logic • Words • Formal reasoning SYSTEMS ANALYSIS AND DESIGN: (A Simplified Perspective) IDS-695 An idea IDS-697 Analysis Time Design and Implementation Completed Information System 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.
