Agile Vs Waterfall

Learn the Difference Between Two Techniques

If you work in the software industry or project management, you’re probably familiar with the terminology agile and waterfall. These approaches are the backbone of any software project. At the start of each software project, teams and organizations decide which approach to follow. Software projects use a technique known as the SDLC to ensure that the final output is of excellent quality. An SDLC defines stages and the organized flow of information from one phase to the next. There are typically six to seven steps in SDLC. Agile and waterfall are two well-known SDLC approaches, although they are completely different.

Dr. Winstn Royce is widely regarded as the founder of the waterfall technique. Moreover, he emphasized the fundamentals of software and system development. If we talk about Agile history, Agile’s background was presented clearly when the group of 17 programmers met in Snowbird, Utah. They planned to build on their efforts and arrive at a more tangible answer to the key development concerns of the moment at this summit. The manifesto for agile development was completed.

Agile Vs Waterfall

Before going deep into the differences between the two processes, it is important to understand the basics of Agile and Waterfall techniques.

What is Waterfall Methodology?

The term “waterfall” refers to a sequential method to development. The conventional approach depends on strict planning and execution of the project’s strategy. It enables the completion of projects more quickly.
According to this technique, the following series of events occurs:

Requirements, Gathering, and Documentation

All succeeding stages of development must adhere to this documentation. The client communicates with the team on the project’s execution solely at the beginning and end.


At this step, the developers attempt to create a form that satisfies all of the customer’s needs.

Coding and unit testing

This stage’s primary objective is to validate codes and unites. Then we evaluate system and user approval.

Handing over the finalized product

Each of these occurrences occurs at a unique level of software development in a typical development project. Typically, each step must complete before the next may begin. Additionally, each has a stage-gate. For instance, before design can begin, a customer must evaluate and accept specifications.

What is Agile Methodology?

An Agile Methodology is a new approach to problem-solving. This iterative development method stresses the speedy delivery of a fully working application. Sprints divide the time spent into manageable chunks. Every sprint has a set time and a continuous list of deliverables.

Difference between Agile and Waterfall Approach

Both techniques may aid in the production of high-quality software by a development team. Knowing the difference between agile and waterfall development may help a team identify the best processes and methodologies for delivering a successful software project, depending on the individual project requirements. Several notable distinctions include the following:

Waterfall Agile comparison
  • Agile is a method that is incremental and iterative; Waterfall is a linear and sequential method.
  • Agile projects divide into sprints, while Waterfall projects divide into phases.
  • Agile enables the completion of several small projects; However, Waterfall enables the completion of a single large project.
  • Agile fosters a product-oriented perspective with a strong emphasis on customer satisfaction; Waterfall fosters a project-oriented mentality with a strong emphasis on effective project delivery.
  • In Agile, we specify requirements daily, while in Waterfall, we specify requirements only once we start the project.
  • Agile allows requirement modification at any point throughout the project’s execution; Waterfall prohibits scope modifications once the project begins.
  • In Agile, testing occurs simultaneously with development; in Waterfall, testing occurs after the build process.
  • Agile allows the whole team to manage the project without a single project manager; Waterfall needs a professional project manager to oversee each step.

Which approach should you follow? Agile or Waterfall

The question arises that which technique you should follow. It is highly dependent on a number of critical aspects. The waterfall approach is the best option when there is no access to a consumer to offer continuous feedback. Agile is suitable for big and complex projects. Moreover, Agile approaches are suitable for projects with continually changing needs due to their flexibility.

Agile development exceeds waterfall development as the approach for product development in recent years, being employed by most development firms. However, according to our TrustRadiussurvey, only 19% of respondents said their organization is more agile than waterfall.
According to respondents’ experiences, the worst aspects of the waterfall methodology are wasted time, difficulty managing requirements, difficulty adapting to changing needs, the fact that it can be costly and difficult to manage, and ultimately, the fact that it can be less satisfying for both the developers working on the project and the customers receiving the finished product.

Industry example of Agile and Waterfall

Agile + Input: Given their expertise in gathering feedback, it’s natural that SurveyMonkey’s product development is agile. Agile techniques place a high value on continuous feedback. Phone conversations, collaborative tools, online conferences, and, of course, surveys may all be used to support this input. Qualitative feedback enables you to develop the authenticity necessary for market success.
When a waterfall function effectively? : While agile enterprises often claim cost reductions as a primary reason for selecting their approach, other experts advise small businesses, particularly startups, that waterfall may be the more financially advantageous alternative. According to technology expert Eric Boersma, waterfall may be a good fit for organizations who know precisely what their product is and what it needs and cannot afford to waste time trying. If your firm places a premium on planning and is usually risk cautious, the waterfall technique’s score-first approach may be optimal.

Difference between Agile and DevOps

DevOps is a hot topic that has been circulating in the industry for a long period. Despite its popularity, there is mounting concern about how it differs from Agile. What could be worse? The Agile and DevOps discussion is a never-ending one in the information technology industry.

Are you an ambitious engineer interested in learning all about DevOps and Agile?. If you want to learn how they differ and preferable, then stick around until the end of this ‘Agile vs. DevOps’ article, where I will share detailed information about both methodologies.

We will discuss the two methodologies in this article, as well as the differences between these two.

Agile Vs DevOps in Software Development
Agile Vs DevOps

What is Agile?

Agile is a project management style that emphasizes the continuous delivery of small, manageable project increments. It is done through iterative development and testing. It was created to replace the conventional waterfall technique, which is recognized for its organized, linear, and sequential life cycle.

Agile facilitates the day-to-day management of complex projects by enhancing communication and cooperation between team members and clients.

What is DevOps?

DevOps is a methodology of software development in which the development team collaborates with the operations team to increase cooperation and efficiency. Additionally, the process requires integrating DevOps ideas and strategies and testing using a set of DevOps tools.

Site Reliability Engineering is the next phase of DevOps implementation. DevOps is a concept that may be implemented in a variety of ways. SRE is much more rigid in terms of the way of doing things and what the team’s clear goals are; particularly, the objective is to maintain the site’s reliability and availability, and to prioritize the activities that contribute to achieve the goal.

The key aspect to remember is that DevOps is not a substitute for Agile! Does it sound incorrect? No, Agile is not on the verge of extinction. However, is DevOps superior? Yes, this is an advancement.

Agile vs. DevOps

Let’s begin by learning about the similarities and differences between the two methodologies. They are not the same, despite their similarities, and some may claim that one is better than other. Therefore, it is critical to know the exact details to clear this uncertainty.

How Agile and DevOps are similar?

How are both methodologies similar if they follow the different methods? Doesn’t it sound wrong? The answer is yes they have some similarities.

Both methodologies depend upon rapid software development. Moreover, their ideas support rapid growth without compromising the client or the processes.

Both emphasize efficiency, effectiveness, and quality across the software development lifecycle. Additionally, they prioritize shorter release cycles.

Both techniques place a greater emphasis on automation and cooperation. When you use Agile or DevOps methodologies, risk tends to decrease with time. On the other hand, risk tends to grow when other techniques, such as Waterfall, are used.

What are the differences between Agile and DevOps?

How Agile differ from DevOps? While both systems promote cooperation to increase speed and efficiency, they vary significantly regarding achieving the target. Before I talk about the technical differences, I want to set the context straight. Hence, I will be talking about a few technical differences which you should be aware of.  The following are some crucial differences in the Agile vs. DevOps debate.


The difference between DevOps and Agile methodologies is how specific tasks are completed. Agile ensures regular communication between teams and clients while DevOps emphasizes testing and delivery. Communication between developers and IT operations is predominantly between programmers and IT operators. Additionally, the Agile approach is a better fit for complex projects, while the DevOps technique is more adapted for end-to-end procedures.


The organizational structure of the teams is one of the major differences between DevOps and Agile. For instance, bigger teams often use DevOps, with the skill set shared across operations and development team members. It implies that each team member will be responsible for completing a particular job or task at each step of the process. On the other hand, agile is better suited for smaller teams that need to accomplish work quickly. Typically, the Agile methodology does not assign particular tasks to team members but instead encourages everyone to share responsibility equally. As a result, all Agile team members should be capable of managing or delegating any aspect of a project at any point in time.


Agile and DevOps methodologies also use a variety of tools, depending on the nature of the project. Kanboard and Jira project management software and Bugzilla server software are popular Agile project management solutions. While DevOps utilizes Amazon Web Services cloud computing, Puppet automation software, TeamCity servers, OpenStack software, and Chef infrastructure.

Attention and Feedback

Agile and DevOps also have significant differences in terms of focus and feedback. While DevOps initiatives prioritize operational and business readiness and get feedback from internal team members, an Agile approach often receives input directly from customers.

In addition, agile teams often use sprints to keep focus, with each sprint lasting shorter than a month. Agile teams design sprints to ensure that available tasks are accomplished in manageable chunks, with the next sprint beginning just after the previous sprint is made.

With DevOps, specific deadlines and standards must be met, some of which might occur daily.

Self EvaluationCustomer Feedback
Shorter release cycles, instant feedbackSmaller release cycles
Emphasis on efficiency and automationEmphasis on speed
Business-friendlyNot optimal for business


To conclude, both methodologies strive to provide high-quality software on schedule. The contrast between agile and DevOps is that agile emphasizes the optimization of the development lifecycle, while DevOps unifies development and operations in a continuous integration/continuous delivery environment.

Agile and DevOps do not have to be mutually independent. Any firm undergoing a DevOps transformation should not quit its current agile operations. DevOps is an extension of agile that focuses on techniques that are not central to agile. Hence, these methods enhance software development and result in higher-quality products.
