A software development methodology can also be referred to as a software development life cycle. It is a defined process for organizing and developing software. Some methods are more popular than others, and theoretically, anyone can come up with new methodologies. However, when dealing with a large project, especially in the professional industry, it can be helpful to learn and adopt existing methods that other software developers are already using.
Whether you have a favorite software development methodology you use frequently or not, it can be helpful to learn about what’s out there. After all, software development comes down to problem-solving, and there are numerous ways to solve different problems. With that in mind, here are 5 software development methodologies you can try in your upcoming projects.
The waterfall software development method is simple and straightforward. If a client knows exactly what they want up front, then this method can be used to develop the software they need. In a nutshell, the specifications are handed off from the client to the project manager who works directly with the development team. The development team uses the specifications to design, build, and test a piece of software before deploying it and handing it back to the client.
The agile software development method relies on collaboration between clients, developers, and testers from the beginning of the project onward. Software is developed in short iterations so that continual feedback can be received. These iterations can be as short as needed for the project. Because of these short bursts of work, not every detail about a project needs to be known up front. If a client’s needs change, the agile method can keep up with minimal risk. An interaction can be planned out, developed, and tested before the next phase is started. Once an iteration is complete, the client can use that part of the software while the next is being developed.
The feature-driven software development method is made up of five processes that all happen simultaneously. In a large organization, this iterative methodology allows for faster development because everyone is allowed to work at the same time. It is not used for single-developer projects. The five processes allow for the following to happen at around the same time: An overall software model is created, a list of features is produced, implementation of the features is planned, the software is designed based on the features, and the software is built.
The spiral software development method is used for high-risk or critical projects, particularly within large organizations that have budgets that can cover this time-intensive process. There are four steps in this development methodology, but the most important step is the risk assessment. If there is failure in this step, then the whole project can be in jeopardy. The other three steps are determining what the objectives are, developing the product, and planning the next phase. If there is too much risk to develop the next phase, then the initial three steps are repeated.
The DevOps software development method combines the development team and operation team, treating them as one as far as projects are concerned, not allowing the teams to be siloed. Of course, each department has different tasks within the process. With DevOps, the development team continuously develops while the operations team handles security, quality assurance, and other necessary operations. This collaboration allows for fast development timelines.
Enroll in a 16-week course and learn software engineering full-time at Devmountain. We offer two software engineering courses, focusing on either Python or Java. The first eight weeks of both courses teach you foundational software development skills. The second half of each course covers your specific programming language interest: Python or Java.
