Developers must be extremely happy due to the opportunities that lie ahead and the foreseen future of software development methodologies. Part of the digital transformation that has taken place in the last few years has been driven by artificial intelligence technologies and algorithms. This artificial intelligence has greatly contributed to software development and, with these great advances, it will continue to grow.
The following software development methodologies (see here) have shaped software development in the last few years and are predicted to be the best software development methodologies in the following years.
Agile digital transformation
Companies are undergoing digital transformation since data has become valuable for obtaining information. Agile methodologies have been the latest addition to this trend, being. They are methodologies that help align digital transformation initiatives with business needs. Since digital transformation is a continuous process, this helps to generate valuable business results rather than waiting for long periods of time.
The extreme programming approach (XP) refers to an agile software engineering methodology. It was created to avoid the development of functions that are not currently required. Its goal is to create a top-notch end product, regardless of the frequent changes in requirements. This method also aims to reduce the costs of the essential software elements. To achieve this, continuous testing and planning is applied.
Compared to the other approaches, XP requires more time and human resources. To the extent that XP is primarily used to create software in a highly unbalanced atmosphere it allows for greater traceability within the modeling procedure. Because of that, it is perfect for complicated projects.
Rapid application development methodology
Rapid Application Development (RAD) methodology is created to take full advantage of software development. It is aimed at reducing the amount of construction required to make the product. It is an abbreviated development process that provides a high-quality system with small investment costs. It is possible that due to the ability to quickly adjust the required elements, it can produce results quickly.
The Spiral Methodology is an extension of the traditional Cascade Model, adding rapid prototypes in an effort to combine the advantages of the top-down and bottom-up concepts. It provides an emphasis on a key area with deliberative iterative risk analysis. It adapts to complex systems on a large scale. The spiral is generally chosen over the Cascade approach for large, expensive and complicated projects.
The Spiral Life Cycle Model is a refined model that focuses on prompt identification of project risks. A spiral project starts small, exploring the risks from day one, making a plan to appropriately manage them, and then deciding if it is worth making the next step (the second iteration in the spiral). Thus, you get a rapid development benefit by continuously reducing the project risk level. Successful use of the Spiral Life Cycle Model depends on conscientious, attentive and knowledgeable management.
It is a Japanese agile methodology, which consists of labeling each of the processes that must be carried out with cards. It has also been called "a highly effective and productive production system". In fact, companies like the Toyota car brand were one of the first to implement it to speed up production processes.
The word Kanban means "visual cards" in Japanese, and it is precisely what you can see. Some developers use virtual cards; however, the best way to do it is with physical cards, which the team can see and feel, to be more effective.
One of the main advantages of Kanban is that in addition to being an Agile methodology, it is also very easy to use and implement, especially because the work team will work together on different aspects of development.
Kanban promotes quality before speed. A well-made product at once is faster than a quick poorly made product that has to be fixed later. Understanding this, we conclude that everything should go well from the beginning and there should be no room for error.
Based on what is known as YAGNI principle, the Kanban methodology produces only what is necessary and required for the system or development to look good, avoiding everything that is considered extra, superficial or unnecessary. In this way, not only is a higher quality product, but time and costs are also optimized.
