Project Management: Agile and Waterfall Methodologies Research

This document presents a comparative analysis of Agile and Waterfall project management methodologies. It begins by defining each approach, highlighting their core principles and frameworks, including the iterative nature of Agile and the sequential phases of Waterfall. The research explores the differences between Agile and traditional project management, emphasizing the iterative structure, interactive user input, and evolutionary delivery of Agile. It contrasts Agile and Waterfall, focusing on scope definition, team synchronization, customer involvement, and funding models. The document outlines the benefits of Agile, such as higher product quality, increased customer satisfaction, and reduced risks, and the benefits of Waterfall, including its simplicity, ease of management, and detailed documentation. The document uses figures and references to support its findings, providing a comprehensive overview of both methodologies and their applications.

Research on Agile PM
and Waterfall PM
Name of the Student
Name of the University

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

Waterfall PM

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
when scope is not
defined
Team Synchronization is limited Smaller and dedicated

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)
