tailieunhanh - Lecture Systems analysis and design methods (7/e): Chapter 19 – Whitten, Bentley

In this chapter you will learn more about the construction and implementation phases of systems development. These two phases construct, test, install, and deliver the final system into operation. You will know that you understand the processes of constructing and implementing a system when you can: Explain the purpose of the construction and implementation phases of the system's life cycle, describe the system's construction and implementation phases in terms of your information building blocks,. | Chapter 19 Systems Construction and Implementation Chapter 19 – System Construction and Implementation Objectives Explain the purpose of the construction and implementation phases of the systems life cycle. Describe the systems construction and implementation phases in terms of your information building blocks. Describe the systems construction implementation phases in terms of major tasks, roles, inputs and outputs. Explain several application program and system tests. Identify several system conversion strategies. Identify those chapters in this textbook that can help you actually perform the tasks of systems construction and implementation. 19- Chapter 19 – System Construction and Implementation 19- Chapter 19 – System Construction and Implementation What Is System Construction and Implementation?

A common but unfortunate synonym is systems development (more frequently used to describe the entire life cycle.)

Build and Test Networks Often system build around existing networks. If system calls for new network functionality, must by built and tested prior to programs that use that it. Roles Network designer Designs LAN and WAN connectivity Network administrator builds and tests Network architecture standards Security Systems analyst Facilitates Ensures that business requirements are not compromised 19- Chapter 19 – System Construction and Implementation Construction Phase – 2.
