Waterfall is reported to have been created and implemented originally as a Process Model. Each  
Email step of work in this model must be finished before moving on to the next, and there is no 
crossover  between the phases of this model. The Waterfall model depicts the sohware 
Subscrib development life cycle  (SDLC) as a logical, sequential flow of data. This means that any stage of 
e development can begin  only aher the previous phase has been finished. The stages of this 
Waterfall model do not cross in  any way.
Waterfall guarantees that each phase is completed before proceeding to the next.
Agile Methodology
The methodology is a flexible and iterative strategy that allows teams to quickly adjust to changing  
project needs and deliver high-quality solutions in less time. In sohware development, agile is  
frequently utilized.
Agile is all about collaboration, customer happiness, ongoing improvement, and breaking large  
projects down into manageable chunks. Agile procedures enable teams to pivot and respond to  
changing client needs while retaining a high level of flexibility by prioritizing cooperation and  
communication. The emphasis on continuous improvement means that teams are constantly  
looking for ways to enhance their processes and offer the best results possible.

When to use Agile vs Waterfall?
Waterfall is the ideal choice for reliable projects since it requires extensive preparation at the outset, 
 taking into account all internal and external factors that influence project performance. The reason 
 for being the best choice for working with the external environment is because it is steady and  
unlikely to alter during the plan, regardless of the project’s size.
However, prior to the introduction of Agile, Waterfall was the preferred approach for external  
projects. As a result, if you can plan a project ahead of time in a low-risk setting, there’s no reason 
to  split it into numerous sprints to produce value each week.
In contrast, given their unstable and unpredictable character, Agile appears to be a more adaptable  
method. In other words, if the product vision and associated requirements can change due to  
external variables such as market dynamics, it is preferable to design and adapt the product utilizing 
 Agile. Agile is also the greatest strategy for ensuring that the project does not spend months in  
development before showing any results. At the end of each sprint, the product owner will be 
able  to test and approve the finished work.
In changing projects that use checkpoints, a lack of sufficient checkpoints creates risk. Waterfall  
because it makes resolving potential flaws uncovered at the end of development more complex. 
As  a result, the concept of when to use agile vs waterfall, extra time set aside for project planning 
does  not guarantee that the design and development phases will run smoothly to the end, 
because most  impediments are both unpleasant and unexpected.
Waterfall vs Agile Pros and Cons:
Below are the major Waterfall vs Agile pros and cons in detail, which will help to choose the 
right
waterfall vs agile project management .
Pros of Waterfall:
l .  Framework: Before beginning the project, the framework establishes a clear knowledge of  
the timeframe and deliverables. The scope of the project will be determined by the custom  
sohware development team and the customers.
2. Documentation: To avoid misconceptions, sohware engineers document each stage of the 
 process.
3. Shared Load: The bespoke sohware development project does not require all your time and 
 attention. Team members focus on different aspects depending on the phase.
4. Hands-off Method: Customers can take a hands-off approach with the waterfall technique.  
There is a requirement till the review session when people set an initial design and project  
plan.
Cons of Waterfall:
l .  Less Customer Involvement: A hands-off approach is not necessarily appropriate for every 
 sohware product. Some clients wish to be more involved in the project’s progress. End-
users  will be frustrated if there is no framework in place to allow for customer interaction.
5. Difficult to Change: The waterfall helps people to follow specific processes and set a  
timeframe. When these components are in place, it is difficult to make modifications when 
the  development team is working against a deadline. Because it is impossible for clients to 
have a  complete understanding before the process begins, adaptability is a crucial aspect of 
the  bespoke sohware development process.
6. Last-minute Testing Session: There is no time constraint between Waterfall and Agile,  
which is one of the waterfall method’s downsides. Although the waterfall approach can 
be

beneficial to sohware development projects, no project has fallen behind schedule. The

remaining 10% of the code accounts for the remaining 90% of development time. As a 
result,  the last testing session will be rushed, resulting in buggy code.
Pros of Agile:
l .  Involvement of stakeholders: This strategy encourages ongoing contact between  
development and the customer.
2. Flexible Deliverables: Because of its hierarchy of importance, an Agile approach allows  
stakeholders to establish deliverables. This is exactly what Agile sohware development  
technique can do if a customer delivers the fundamental sohware products before the whole 
 suite.
3. Easy to adapt: One of the most significant aspects of Agile development is adaptability. It  
also has a significant impact on custom sohware development projects. Some sohware  
outsourcing services assist customers in transforming their notions about what they require  
from a sohware solution. The sohware development team can then adjust the scheduled  
sprints accordingly.
4. High-quality user-friendly software: Because clients provide feedback aher each sprint,  
the sohware development team employs the agile technique. It will result in an easy-to-use  
sohware product.
Cons of Agile:
l .  Commitment: Agile technique works best when the entire bespoke sohware development  
team commits to the project. It is difficult for sohware outsourcing service providers and  
developers to have a lot going on at the same time.
5. High cost and longer t ime: While time-boxed sprints enable scheduling, employees may fail 
 to complete some deliverables on time. Furthermore, adding additional sprints may incur  
significant costs.
6. Communication: Because Agile necessitates a high level of collaboration, bespoke sohware  
development teams must communicate with one another.
Why Methodology should be Used?
You are now aware that each methodology has advantages and disadvantages. Knowing this 
makes  it easier for us to determine how you can use and when to use Agile vs Waterfall 
approaches in  your projects
What is Waterfall Methodology appropriate for?
Waterfall methodology places a high value on meticulous planning and modeling prior to  
implementation. As a result, it stands to reason that it is not ideal for clients who are unsure of 
what  they anticipate from you. They are also unsuitable for large and complex projects that 
require  extensive client involvement before being released.
Reasons why the Waterfall methodology is appropriate:
Projects in which you collaborate with other organizations or remote workers (since everything 
is  clear and there is no opportunity for ambiguity).
Projects with a predetermined scope, timeline, and 
budget.  Smaller, more defined, and easier projects.
Projects with a client who is not present.
What is an Agile approach suitable 
for?
Agile is essentially a method of delivering a product progressively and iteratively. You’re still using a  
linear strategy if you only provide your product in increments (or batches) rather than iterations 
(that  is, repeating the process of planning expectations and requirements for each increment). The 
entire  procedure should be repeated for each increment in an Agile methodology to ensure that 
every  adjustment or modification is accounted for in the following increment. In an Agile 
approach, each  increment looks like this.
Reasons why Agile is appropriate:
Projects in which your business oversees the entire 
process  Projects with the potential for changing 
requirements
Projects that are larger, ambiguous, and 
difficult  Projects involving a client
You should now be familiar with the fundamentals of both the Waterfall and Agile. In the Waterfall  
and Agile methodologies section, we saw various elements that could be decisive 
considerations.
