The Systems Development Life Cycle

and Project Management:

Addressing the Challenges of Building

AIS Systems

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

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

Phases of the Systems Development

Life Cycle

• Planning Phase

• Analysis Phase

• Design Phase

• Implementation Phase

• Maintenance Phase

The Recursive Nature of the SDLC

Project Management: A Few Terms

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

Challenges of IT Project Management

Constraints of IT Projects

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.

PERT Chart

Project Management Tools

• A Gantt chart is a graphical representation of

the project schedule by mapping the tasks to

a project calendar

Gantt Chart

Will the Systems Be Useful?

Will it be Used?

Usefulness and Ease of Use?

• What can be done to address perceptions of usefulness of a new accounting information

system?

• What can be done to address perceptions of ease of use of a new accounting information system?

• 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
