System and Design-MIS-Seminar,Presentation

  1. 1. SYSTEM AND DESIGN
  2. 2.  INTRODUCTION  VARIOUS APPROACHES
  3. 3. INTRODUCTION :System:A system can be defined as set of elements arranged in an orderly manner to accomplish an objective. The purpose of developing a new system is complex data processing. To satisfy needs for Top level, Middle level and lower level people in the organisation.
  4. 4. Analyse Existing system:1)Careful study on Existing system 2)Evaluating the system (Technically , Economically and operationally). 3)Compare old and new system developed.
  5. 5. There are two types of approaches  Prototype Approach  Life cycle Approach
  6. 6. 1)Prototype Approach : It is the process progressively ascertaining information needs, developing methodology and ensuring that it satisfies the needs of the users. 2) Life Cycle Approach : It is applied for small systems or independent systems development like payroll basic financial accounting,Finished goods accounting,Dispatching and other processing etc.
  7. 7. Prototype Approach
  8. 8. Mission and Goals Develop & Test Identify information needs Refine needs Define system boundaries and scope Modify the Prototype Define system objectives Develop revised prototype Documentation NO Training Examine feasibility Develop Initial Is User satisfied Implement in Parallel Yes Initial Prototype Develop the application Review
  9. 9. Life Cycle Approach
  10. 10. System Application Program Specification Assess Feasibility Develop System Information Requirement Install the system Conceptual Design Conduct awareness and training Physical Design Operate the system System Specification Review of Audit
  11. 11. Prototype Approach Life cycle Approach 1)Open system with high degree of Closed system with little uncertainty about the information uncertainty about information needs needs 2)Necessary to try out the ideas application and efficiency of information No need to try out the application or information as it is already proven 3)In prototype approach necessary to control cost of design and development, Experimentations are necessary Design and application are fully determined with clarity, experiments are not necessary 4)User want to try out the system before he commits specification The user is confident and confirm the specification 5)The system and application is custom oriented System and application is universal governed by principles and practice
