Project Management Methodologies: Agile and Waterfall in the PLC

This essay provides a comprehensive overview of project management methodologies, focusing on a detailed comparison between the Agile and Waterfall approaches. It begins by defining methodology and its role in project management, then delves into the specifics of Agile and Waterfall, highlighting their benefits, drawbacks, and key differences. The essay further explores how each methodology relates to the project life cycle, illustrating their respective applications in software development and project management. It references various sources and provides a structured analysis suitable for understanding the practical implications of choosing between Agile and Waterfall methodologies in different project scenarios. Desklib offers a wide range of past papers and solved assignments to aid students in their studies.

Project Management Methodology
A methodology is defined as a systematic process which is used to analyse hypothetical
and practical information about any research project. The methodology comprises the
theoretical analysis of any research and also associated with a branch of experience.
Approach refers to a process which involves many methods such as a theoretical model,
qualitative analysis, and quantitative analysis (Amoako, Meredith, & Loyd, 2018). A
methodology is a process which is used by project organization to examination,
planning, and accomplishes their goals and targets. According to PMI panel approach is
defined as a process of organization, observes, and rules which is used by plan
managers, and staffs of any organization or business (Cooper, & Sommer, 2018). The
word approach plays a major role in plan organization because it transports a stage to
inspect, plan, and complete aim or objective in any association system. Many bosses or
scheme staffs use the methodology in project organization because it produces a
hypothetical inspection of any investigation idea.
There are numerous types of methods available in plan organization such as
 Agile
 SDLC
 Waterfall
 Project Management Body of Knowledge (PMBOK)
 PRINCE2
Agile approach
Agile method is well-defined as a course which supports to provide constant
iteration and difficult in the software technique. The major profit of this procedure is
that it offers development and challenging procedure rather than waterfall policy. This
methodology also allows additional interaction between operators, clients and employs
(Daniel, & Daniel, 2018). It is a team-based procedure which is utilized by various
project organizations and it is a very high level of approach which is only utilized for big
developments. There is several procedure contains in this procedure such as extreme
programming, crystal, lean growth, DSDM, and scrum, and FDD. For all procedure agile
method is unique and they segment a common dream and mission.

Benefits of the Agile Method
 It is motivated by the client’s process
 This process is a self-organized procedure
 It sustains the excellence of progress
 This approach is based on the incremental development
Drawbacks of the agile method
 This process is not useful for small schemes
 It contains a professional to take a decision
 Expensive procedure rather than other methodologies
 Need complete step by step technique
Waterfall approach
Waterfall approach is a type of procedure which is also named as liner life cycle
prototypical. This method follows a consecutive instruction therefor project
organization team only move in one direction to complete their objectives (Davies,
Manning, & Söderlund, 2018). This approach is very humble to appreciate and use and
in which the first phase completed after that next phase can create. Fundamentally this
type of method is used for the small scheme and where no insecurity is compulsory. At
the end of every stage, a review technique is taking place to measure whether the
development method is on the right way or not (Misopoulos, Michaelides, Salehuddin,
Manthou, & Michaelides, 2018).
Benefits of the waterfall process
 It is very humble and easy for usage
 Relaxed to accomplish
 This process can be used for minor schemes
 Steps are used and completed one at a period
 Practice and results are well conventional
 This process can be used to accomplish dependencies
Drawbacks of the waterfall method
 This process cannot use for large schemes
 Not more effective procedure
 Very problematic method to transfer back to previous stages

 Testing technique start when the growth process is done
Agile vs. Waterfall approach
Agile approach Waterfall approach
It splits the expansion procedure into
sprints
It splits development way into stages
It follows an incremental method It is a sequential design method
It is a elastic method It is quite a rigid method
It is a group of many projects It is a single project
Requirements can be transformed at
every step
The system cannot modify once the
development method initiate
The plan is swotted after each phase The test plan is not revised at the time of
development procedure
Role of Agile and Waterfall methodology in project life cycle
The agile approach in project life cycle
Agile development method is very useful for project life cycle because this
process promotes the development iterations in the plan life cycle (Gal, Filip, & Dragan,
2018) Agile plan lifecycle involve many software developments such as adaptive
software development, DAD, agile modelling, scrum, Kanab, extreme programming,
DSDM, and lean software development.

Waterfall process in project life cycle
The waterfall project life cycle involves some steps such as requirements, system
design, implementation, testing, deployment of system and maintenance. Waterfall
project life cycle involves a few steps such as planning, requirements, analysis of
project, design, coding part, testing process, and deployment process.
