What is Agile? Software development without a formal methodology. Agile methodologies and models. A collection of values, goals, process documentation, and activities that drive the development of quality software.
In an Agile environment, there are no design patterns or formal architectural schemas. The term “agile” comes from the Italian word “agilitude,” which means luck or fortitude. Invented by Jean Piaget in the 1940s, agile is an informal set of rules for software development that prioritize the identification, estimation, and creation of requirements. The agile methodology then applies these requirements throughout the project in a series of small, manageable stages.
The principle goal of agile methodology is to identify, document, and achieve proper requirements before the development of the software begins. In an agile development environment, this chain of communication is continuous and is called the “feedback cycle.” This cycle allows those involved to monitor the status of the project at each stage. As well as being a great source of information, the feedback cycle also provides the ability for those who are involved in the project to make changes and get quick feedback.
The Agile Manifesto states, “Working software is the hallmark of effective management. Working software builds capacity-driven business processes that can be applied to any existing or future information system.” What is agile software development, therefore, is software development using agile methodology that focuses on developing software that is better suited to the requirements of the customer before the development process actually begins. By removing some of the constraints associated with the waterfall approach and development models, Agile develops software development that can adapt to changing customer requirements and market conditions. Because Agile uses the customer satisfaction approach, Agile also relies heavily on feedback from the developers themselves.
One of the main differences between agile and waterfall software development is that agile software development relies much less on the use of testing. During the agile development process, there is a greater emphasis on getting the software right the first time and getting user feedback to ensure that the requirements were properly met by the development team. In contrast, in waterfall processes, a testing phase is frequently used to validate the functionality of the software design.
Agile methods are based upon the idea that software is a living thing, which continually changes and grows with the changing world around it. This concept has caused many problems, including the clash between Agile and Six Sigma. Agile is strictly waterfall-based, and the two cannot exist together because they would both be incompatible with each other. Six Sigma, on the other hand, takes waterfall concepts and implements them into its design.
Despite the fact that Agile is a more radical approach than waterfall-based development, many business managers have found that it suits their business needs better. Agile has been especially popular in the software development industry, as it allows the business to focus more on the creative side of the development process. It also provides the necessary flexibility that some organizations need to deal with rapid innovations. The overall effect of Agile is one of continuous improvement and growth. This is why many organizations that switch over to agile software development choose this method rather than the traditional methods.
What is Agile software development? Agile is a software development process that delivers software in a series of steps. These steps can become long or seemingly endless, depending on the scope and complexity of the software involved. Agile differs from other software development methods in that it tries to get software development as close to a “One Feature, One Action” process as possible. Although Agile does not try to implement all of the required features of software development, it does make sure that most of them are implemented, which makes it very efficient and flexible.
