Project Management Methodology
The methodology is characterized as a procedure which is theoretical, and
orderly investigation of connected strategies in any research. It gives a hypothetical
investigation of any exploration and also connected with a division of learning. The
methodology is characterized as an examination technique that gives an approach by
which investigation of information or data is to be embraced. A methodology is a
procedure which is utilized by a project administration to investigate, arranging, and
achieve their objectives and targets (Turner, & Ledwith, 2018). As indicated by PMI
board methodology is characterized as a procedure of system, practices, and principles
which is utilized by project supervisors, and representatives of any association or
industry. Numerous directors or venture workers utilize the strategy in project
management since it delivers a hypothetical examination of any exploration thought.
The term methodology plays a significant part in project administration because it
delivers a platform to examine, strategy, and achieve goal or objective in any
organization system.

Types of project management methodologies
There are many types of methodologies available in project management such as
 SDLC

 Waterfall
 Agile
 Project Management Body of Knowledge (PMBOK)
 PRINCE2
Waterfall methodology
Waterfall technique is a sort of process which is also called as liner life cycle
methodology. This approach takes after a consecutive request therefor project
administration group just move in one way to achieve their (Chari, & Agrawal, 2018).
This system is exceptionally easy to comprehend and utilize and in which the primary
stage finished after that next stage can start. Essentially, this sort of approach is utilized
for the little task and where no uncertainty is required. Toward the finish of each stage,
a survey procedure is occurring to gauge whether the venture procedure is on the
correct way or not.
Advantages of the waterfall process
 It is very modest and stress-free to use
 Calm to manage
 Can be utilized for small plans
 Stages are used and finished one at a time
 Procedure and results are well ordinary
 Can be utilized to achieve dependencies
Disadvantages of the waterfall process
 Cannot be used for large developments
 Less effective procedure
 It is a difficult procedure to move back to earlier stages
 The challenging technique starts when the development process is completed
Agile methodology
An agile technique is characterized as a procedure which gives a consistent cycle
and testing in the software procedure (Rajeev, & Hejib, 2018). The main benefit of this
method is that it gives advancement and testing process as opposed to the waterfall
technique. This approach likewise takes into consideration more communication
between clients, and supervisors and utilizes (Cooper, & Sommer, 2018). It is a group

based process which is utilized by numerous venture administrations and it is a high-
level approach which is utilized for abnormal state ventures. There are numerous
procedures includes in this strategy, for example, extraordinary programming, gem,
lean advancement, DSDM, and scrum, and FDD (Sun, & Schmidt, 2018).

Advantages of the Agile Model
 It is dedicated to the customer's procedure
 It is a self-organized method
 It maintains the excellence of progress
 It is based on the incremental development
Disadvantages of the agile process
 It is not a valuable process for minor plans
 It involves an expert to take a judgment
 Costly method rather than other approaches
 It is a step by step procedure

Comparison between Agile and Waterfall methodology
Agile methodology Waterfall methodology
It divides the progress method into
sprints
It divides the development procedure into
stages
It monitors an incremental procedure It is a consecutive project method
It is a flexible procedure It is quite a rigid procedure
It is a collection of many plans It is an only one project
Requirements can be transformed at any
stage
The procedure cannot change once the
growth technique begin
The strategy is reviewed after each step The test plan is not reviewed at the time of
the expansion procedure
Role of Agile and Waterfall process in Project life cycle
Agile process in project life cycle
The agile process is extremely valuable for the venture life cycle since this
procedure advances the improvement emphases in the project life cycle (Hassani,
Bouzekri, & Abouabdellah, 2018,). Agile project lifecycle includes numerous product
advancements, for example, versatile programming improvement, DAD, coordinated
demonstrating, scrum, Kanab, extraordinary programming, DSDM, and lean
programming advancement. Agile lifecycle includes the development, generation, idea,
and retirement stages.
Waterfall process in project life cycle
The waterfall project life cycle includes a few stages, for example, prerequisites,
framework outline, usage, testing, sending of framework and support. Both
methodology play an important role in project life cycle and also provide complete
research cycle which is used by project manager.
