Software development methodologies are system models used to implement software development processes that help ensure that software product delivery is predictable, on time, and within budget.
These methodologies are typically associated with different lifecycle models such as Waterfall, Agile, and Scrum. Each approach has a different set of methods, and the right choice depends on the type of project, the scope and complexity of the project, its timeline, and the team’s experience.

The difference between Waterfall, Scrum, and Kanban software development methodologies
This guide will show how each methodology is unique and outline the major advantages of employing each.
Waterfall is an organized, step-by-step methodology for software development that requires following a sequence of elements in order. It does not allow for deviation, so teams have to complete one step before moving on to the next and cannot go back and revisit previous stages.
Two things are essential to ensure the success of any Waterfall project: comprehensive documentation and distinct stages.
Documentation is essential to the success of the Waterfall process, as there is no turning back once it has started. All stakeholders must have a clear grasp of the requirements for the project before initiation to ensure the project runs effectively and each goal is accomplished.
The strict, linear nature of the Waterfall process rooting is in its manufacturing origins, where specific steps had to be completed before the next phase could begin. For teams to adhere to the Waterfall process, they must stick to a strict schedule and continue to progress along the chain of events.
The Waterfall approach is beneficial because it offers teams a distinct roadmap of the journey from the start to the end of a project. In comparison, methodologies such as Agile do not provide such a transparent structure which can be problematic for teams who favor structure and clarity.
Additionally, it gives the team a unified understanding of objectives and standards so that everyone is working with the same data.
A further advantage of creating a meticulously outlined project plan is that it defines concise interconnection methods.
When external groups take part in different elements of the venture, they’ll be more informed of the desired outcome, how it should be executed, and how their input is required.
Kanban is an Agile-aligned software development approach that stresses increased effectiveness via adaptability. It allows teams to adjust their work and resources throughout the task, facilitating a more dynamic flow. The Kanban panel is the cornerstone of Kanban, which can help teams arrange their sprints and keep an eye on their ongoing work.
Different groups of Backlog, On Deck, In-Progress, and Completed give the team the ability to have a clear understanding of their workload and what requires to be executed next. This structure empowers the team to have a thorough view of their workflow.
This board helps the team in a few ways – keeping them all informed, supervising progress on tasks, and presenting a way to protect responsibilities from becoming too overwhelming. Each time a job progresses, the team will update the panel as necessary.
Kanban emphasizes delivering projects in increments, sharing results, and introducing changes gradually. One of the chief benefits of using Kanban is having more informed clients. Splitting projects into smaller components and delivering them sequentially makes customers aware of progress. This engages them more in the project and allows them to give feedback. That input can help to readjust the emphasis of upcoming project portions for a better outcome.
Kanban also fosters a shared appreciation. A common standpoint of the team’s workflow helps understand individual duties and how they correlate to the project. Having a mutual understanding of how the workflow operates ensures that everyone is tied to their tasks and the project’s success in general, which is foundational to Kanban.
Scrum, a section of the Agile system, is a tremendously prevalent programming advancement approach. It contains more stringent sprints than Kanban and improves efficiency in circular development forms.
The Scrum team contains three essential jobs: the Product Owner, Scrum Master, and Development Team. Every part is accountable for their tasks, and they cooperate across the sprints to accomplish their shared objective. Scrum employs short sprints to create an ongoing development cycle to help teams become more productive.
These cycles come with steady opportunities to assess the workflow and use retrospective templates to take notes and refine the processes. This system allows teams to progress on small projects repeatedly, improving their work.
Being a part of a Scrum team entails collaborating with the same set of people on numerous sprints. This allows for reliable expectations and encourages a strong team relationship, two main advantages of using the scrum methodology for development teams.
Scrum also improves overall polish. Because Scrum offers rigorously enforced sprints with well-defined objectives, teams can ensure that the end product of any project will have reliable quality. The predictability of the output makes Scrum a popular choice for teams that need to deliver tangible results regularly.
Suppose you want to understand more about scrum software development methodology and understand what a site reliability engineer is. In that case, Baylor University offers a Master’s in Computer Science online degree program that prepares its students for lucrative roles in Software Engineering. The coursewill prepare students for leadership in the computing industry by covering a whole host of topics from programming to systems design and theory, and is designed for students with a bachelor’s in computer science or a STEM-focused undergrad degree.
Successful software development methodologies
Software development methodologies are critical to successful software development projects. Waterfall, Scrum, and Kanban are today’s three significant methodologies for creating successful products and services.
Each of these methodologies has unique advantages, and it is up to the development team to find the most suitable approach for their specific project. Successful software projects are often built with a mixture of the three significant methodologies, allowing a team to craft solutions in the best manner possible.
