tailieunhanh - Lecture Systems Analysis and Design in a Changing World (3rd Edition) - Chapter 16: Making the system operational

Learning objectives in chapter chapter 16: Describe implementation and support activities, choose an appropriate approach to program development, describe various types of software tests and explain how and why each is used,. | Chapter 16: Making the System Operational Systems Analysis and Design in a Changing World, 3rd Edition Learning Objectives Describe implementation and support activities Choose an appropriate approach to program development Describe various types of software tests and explain how and why each is used Learning Objectives (continued) List various approaches to data conversion and system installation and describe the advantages and disadvantages of each Describe different types of documentation and the processes by which they are developed and maintained Describe training and user support requirements for new and operational systems Overview This chapter focuses on activities of implementation and support phases of systems development life cycle (SDLC) Implementation activities occur before system is turned over to users Implementation consumes more time and resources than earlier phases of the SDLC Support activities occur after system becomes operational and may continue for years Activities of the Implementation and Support Phases Program Development Program development is time consuming One-third of development labor One-third to one-half of project development schedule Programming and testing considerations: Required resources Managerial complexity System quality Order of Implementation Input, process, output (IPO) development order Based on data flow through system Simplifies testing User interfaces developed early to reduce change Disadvantage is late implementation of outputs Structured design – IPO order based on system flowchart and structure chart OO design – IPO order in package diagrams Order of Implementation (continued) Top-down and bottom-up order from traditional structured design and structured programming Top-down begins with top structure chart module Always a working version of program Requires three or more iterations to complete Bottom-up begins with modules at lowest level of structure chart Many programmers can begin | Chapter 16: Making the System Operational Systems Analysis and Design in a Changing World, 3rd Edition Learning Objectives Describe implementation and support activities Choose an appropriate approach to program development Describe various types of software tests and explain how and why each is used Learning Objectives (continued) List various approaches to data conversion and system installation and describe the advantages and disadvantages of each Describe different types of documentation and the processes by which they are developed and maintained Describe training and user support requirements for new and operational systems Overview This chapter focuses on activities of implementation and support phases of systems development life cycle (SDLC) Implementation activities occur before system is turned over to users Implementation consumes more time and resources than earlier phases of the SDLC Support activities occur after system becomes operational and may continue for .
