Agile PM vs Waterfall PM: A Comparative Study

This presentation provides a comparative study of Agile PM and Waterfall PM, including their characteristics, working, and differences. It also highlights the benefits of both methodologies to the project. The Agile methodology follows an iterative approach based on guiding and planning of project processes, while the Waterfall model is defined as a sequential and linear approach towards SDLC. Agile PM leads to higher product quality, high customer satisfaction, increased control over the project, and reduced risks and Fast Return on Investment (ROI). On the other hand, the Waterfall model is simple and easy to use, easy to manage due to the rigid model, and provides detailed documentation that provides resistance to changes.

Agile PM
 Agile follows an iterative approach based on guiding
and planning of project processes
 Agile methodology divides the project into sub-
sections, which are known as iterations (Rasnacis and
Berzisa 47)
 Each of the sub-sections are reviewed by the project
team, which also includes project stakeholders.

Working of Agile PM
 Agile PM adopts practices based on continuous
integration and continuous deployment
 Agile PM requires teams to evaluate the cost and time
within the progress of work
 The role of project manager is distributed within the
team members of APM

Waterfall PM
 The waterfall model is defined as a sequential and
linear approach towards SDLC
 The Waterfall PM puts focus on logical progression
approach (Alshamrani and Bahattab 106)
 The Waterfall model follow phases such as analysis,
planning, initiation, design, construction, testing,
deployment and continuous maintenance

Working of Waterfall PM
 The Waterfall PM puts their primary emphasis on
documentation and the source code
 The working strategy of this model follows a structured
approach
 They provide identifiable milestones within the
development process

Changes are welcomed

defined
Team Synchronization is limited Smaller and dedicated

Availability
Customer involvement is
required at milestones
Customer availability is
required throughout

contracts
Price is defined as per
materials and time

Benefits of Agile to Project
 Agile methodology leads to higher product quality
 Leads to high customer satisfaction
 Increases control over project (Serrador and Pinto
1049)
 Reduced risks and Fast Return on Investment (ROI)

Benefits of Waterfall Model to Project
 Simple and easy usage
 Easy management due to rigid model
 Start and end points of each of the phases are set
 Detailed documentation provides resistance to changes
