Learning Objectives• LO#1 Describe each phase in the systems

development life cycle.• LO#2 Explain the core principles of information

systems planning• LO#3 Define project management and describe the

positions of those who lead the project.• LO#4 Explain why IT projects are challenged and the

tools that are used to overcome these challenges.• LO#5 Explain why users do or do not want to use a

new information system designed for them.

The Systems Development Life Cycle

• The systems development life cycle (SDLC) is the process of creating or modifying information systems to meet the needs of its users.

• The SDLC is generally viewed as the foundation for all systems development that people use to develop such systems.

Project Management: A Few Terms

• Project management is the planning, organizing, supervising and directing of an IT project.

• A project manager is the lead member of the project team that is responsible for the project.

• The project sponsor will often be a senior executive in the company who takes responsibility for the success of the project.

Project Management Tools

• PERT chart – works to identify all tasks of a project– Notes task sequencing and task dependence.– Notes critical path – the path that represents the

minimum amount of time needed for the completion of the project when sufficient resources are allocated.

Summary

• The systems development life cycle is the foundation for all systems development, models, and methodologies that people use to develop such systems. The SDLC has five phases: Planning, Analysis, Design, Implementation and Maintenance.

• Project managers and project sponsors each play key roles in managing system development.

• Many AIS and IT projects fail to meet expectations. If we can understand the reason these projects fail, we can better design the project management process to address these reasons.– Scope, time and cost represent the triple constraints of project

management• AIS developers, project managers and project sponsors should all be

aware of how a new system is perceived by those who will ultimately be using the new system.
