tailieunhanh - Lecture Accounting information systems (13/e) – Chapter 20: Introduction to systems development and systems analysis

The purpose of this chapter is: Explain the five phases of the systems development life cycle, discuss the people involved in systems development and the roles they play, explain the importance of systems development planning and describe planning techniques, discuss the various types of feasibility analysis and calculate economic feasibility. | Introduction to Systems Development and Systems Analysis Chapter 20 20-1 Learning Objectives Explain the five phases of the systems development life cycle. Discuss the people involved in systems development and the roles they play. Explain the importance of systems development planning and describe planning techniques. Discuss the various types of feasibility analysis and calculate economic feasibility. Explain why system changes trigger behavioral reactions, what form this resistance to change takes, and how to avoid or minimize the resulting problems. Discuss the key issues and steps in systems analysis. 20-2 Systems Development Life Cycle (SDLC) 20-3 Who Is Involved in the SDLC? Information Systems Steering Committee Executive level, plans and oversees IS function; facilitates coordination with integration of systems activities Project Development Team Plan and monitor project progress Programmers Write and test programs according to analysts specifications Systems Analysts . | Introduction to Systems Development and Systems Analysis Chapter 20 20-1 Learning Objectives Explain the five phases of the systems development life cycle.

Information Systems Steering Committee Executive level, plans and oversees IS function; facilitates coordination with integration of systems activities Project Development Team Plan and monitor project progress Programmers Write and test programs according to analysts specifications Systems Analysts Determine information needs, prepare specifications for programmers Management Get users involved in the process, provide support for development projects, align projects to meet organizations strategic needs Users Communicate needs to system developers, help design and test to ensure complete and accurate processing of data 20-4 Systems Development Planning Proper planning provides for achieving goals and objectives For systems development, two plans needed: Master Plan Long-range and authored by steering committee outlining prioritized projects and timetables Project Development Plan Specific to a project and authored by the project team identifies people, hardware, software, and financial resources needed 20-5 Planning Techniques Program evaluation and review technique (PERT) Diagram that depicts all project activities that require time and resources with completion estimates. Determines critical path. Gantt chart Bar chart that organizes activities on the left hand side and project time .
