Overview
  • Keys to successful system development
    • Thorough systems analysis and design
    • Understanding what business requires
  • Systems analysis – process of understanding in detail what a system should accomplish
  • Systems design – process of specifying in detail how components of an information system should be physically implemented
  • Systems analyst – uses analysis and design techniques to solve business problems using information technology

the analyst as a business problem solver
The Analyst as a Business Problem Solver
  • Has computer technology knowledge and programming expertise
  • Understands business problems
  • Uses logical methods for solving problems
  • Has fundamental curiosity
  • Wants to make things better
  • Is more of a business problem solver than a technical programmer

Systems Analysis and Design in a Changing World, 4th Edition

analyst s approach to problem solving
Analyst’s Approach to Problem Solving

Research and understand the problem

Verify benefits of solving problem outweigh the costs

Define the requirements for solving the problem

Develop a set of possible solutions (alternatives)

Decide which solution is best and recommend

Define the details of the chosen solution

Implement the solution

Monitor to ensure desired results

types of information systems
Types of Information Systems
  • Transaction processing systems (TPS)
    • Capture and record information about organization’s transactions
  • Management information systems (MIS)
    • Take information captured by TPS
    • Produce reports for planning and control
  • Decision support / knowledge-based systems (DSS/KBS)
    • Explore impact of available options or decisions (what-if scenarios)
    • Automate routine decision making
