Sad in changing world chapter1 (1) Presentation Transcript

  • 1. 1 Systems Analysis and Design in a Changing World, 4th Edition 1 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
  • 2. 1 Systems Analysis and Design in a Changing World, 4th Edition 2 Analyst’s Approach to Problem Solving Verify benefits of solving problem outweigh the costs Research and understand the problem Define the requirements for solving the problem Develop a set of possible solutions (alternatives) Define the details of the chosen solution Monitor to ensure desired results Decide which solution is best and recommend Implement the solution
  • 3. 1 Systems Analysis and Design in a Changing World, 4th Edition 3 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
  • 4. 1 Systems Analysis and Design in a Changing World, 4th Edition 4 Types of Information Systems (continued) Enterprise applications Highly integrated systems that support company-wide operations and data Often combine aspects of TPS, MIS, DSS/KBS Enterprise Application Architecture
  • 5. 1 Systems Analysis and Design in a Changing World, 4th Edition 6 Technical Knowledge and Skills An analyst should have fundamental technology knowledge of Computers / peripheral devices (hardware) Communication networks and connectivity Database and database management systems (DBMS) Programming languages (for example, VB.NET or Java) Operating systems and utilities
  • 6. 1 Systems Analysis and Design in a Changing World, 4th Edition 7 Technical Knowledge and Skills (continued) Analyst uses tools Software productivity packages Integrated development environments (IDEs) for programming languages CASE tools, testing, documentation support, reverse engineering, configuration management Analyst understands SDLC techniques Project planning, systems analysis Systems design, database design, network design Construction, implementation, systems support
  • 7. 1 Systems Analysis and Design in a Changing World, 4th Edition 8 Business Knowledge and Skills Analyst must understand Business functions performed by organization Strategies, plans, traditions, and values of the organization Organizational structure Organization management techniques Functional work processes Systems analysts typically study business administration/management in college with a major in CIS or MIS
  • 8. 1 Systems Analysis and Design in a Changing World, 4th Edition 9 People Knowledge and Skills Systems analysts need to understand how people Think Learn React to change Communicate Work (in a variety of jobs and levels)
  • 9. 1 Systems Analysis and Design in a Changing World, 4th Edition 10 People Knowledge and Skills (continued) Interpersonal and communication skills are crucial to Obtaining information Motivating people Getting cooperation Understanding the complexity and workings of an organization in order to provide necessary support
