TAILIEUCHUNG - Lecture Systems Analysis and Design in a Changing World (3rd Edition) - Chapter 2: Approaches to System Development

Learning objectives for chapter 2: Explain the purpose and various phases of the systems development life cycle (SDLC); explain the differences between a model, a tool, a technique, and a methodology; describe the two overall approaches used to develop information systems: the traditional method and the object-oriented method,. | Chapter 2: Approaches to System Development Systems Analysis and Design in a Changing World, 3rd Edition Learning Objectives Explain the purpose and various phases of the systems development life cycle (SDLC) Explain the differences between a model, a tool, a technique, and a methodology Describe the two overall approaches used to develop information systems: the traditional method and the object-oriented method Learning Objectives (continued) Describe some of the variations of the system development life cycle (SDLC) Describe the key features of current trends in system development: the spiral model, eXtreme Programming (XP), the Unified Process (UP), and Agile Modeling Explain how automated tools are used in system development Overview Systems development life cycle (SDLC) Provides overall framework for managing system development process Two main approaches to SDLC Traditional approach: structured systems development and information engineering Object-oriented approach: object technologies requires different approach to analysis, design, and programming All projects use some variation of SDLC Systems Development Life Cycle (SDLC) Systems development project Planned undertaking with fixed beginning and end Produces desired result or product Can be a large job of thousands of hours of effort or a small one month project Successful development project: Provides a detailed plan to follow Organized, methodical sequence of tasks and activities Produces reliable, robust, and efficient system Phases of the Systems Development Lifecycle (SDLC) Project planning: initiate, ensure feasibility, plan schedule, obtain approval for project Analysis: understand business needs and processing requirements Design: define solution system based on requirements and analysis decisions Implementation: construction, testing, user training, and installation of new system Support: keep system running and improve Information System Development Phases SDLC and .
