5. About the course
Systems Analysis and Design (SAD) is an exciting, active field in which analysts continually learn new techniques and approaches to develop business systems more effectively and efficiently.
The course gives an understanding of organizational behavior concepts like change management and team building which are very important for any type of business process.
It gives the information on how all projects require analysts to gather requirements, model the business needs, and create blueprints for their business system.

6. Books and Resources
Essentials Of Systems Analysis And Design 6th Edition by Joseph S. Valacich, Joey F. George and Jeffrey A. Hoffer
Systems Analysis & Design, approach, 5th Edition by Denis, Wixom and Roth

13. Introduction (cont.)

14. A Modern Approach to Systems Analysis and Design
1950s: focus on efficient automation of existing processes
1960s: advent of 3GL, faster and more reliable computers
1970s: system development becomes more like an engineering discipline
1980s: major breakthrough with 4GL, CASE tools, object oriented methods
1990s: focus on system integration, GUI applications, client/server platforms, Internet
The new century: Web application development, wireless PDAs, component-based applications

15. Types of Information Systems and Systems Development
Transaction Processing Systems (TPS)
Automate handling of data about business activities (transactions)
Process orientation
Management Information Systems (MIS)
Converts raw data from transaction processing system into meaningful form
Data orientation
Decision Support Systems (DSS)
Designed to help decision makers
Provides interactive environment for decision making
Involves data warehouses, executive information systems (EIS)
Database, model base, user dialogue

16. Types of Information Systems and Systems Development (cont.)

17. Systems Development Life Cycle (SDLC)
Planning
Analysis
Design
Implementation

18. Summary In this lecture we learned about:
Information systems analysis and design.
The different types of information systems.
The phases in the information Systems Development Life Cycle (SDLC).

19. Overview of Next lecture
We will continue our discussion on SDLC
Precisely, we will talk about the problems with the existing waterfall approach
We will also see some other SDLC: Methodologies
