What is Agile? agile is a shortened term of Agile Software Development. Agile (the shortened form) stems from the first description of Agile in a paper by Jean M. Van de Velde and Michael J. Cafarella (ATI Press, 2005). Agile is a family of generic software development methods that have been used for 20 years in a wide variety of fields. The methods have a strong emphasis on flexible and creative problem solving and have been used to deliver products faster than with more traditional methods.
Agile software development is the application of those principles of Agile computer software design to various management systems, especially project management. The original Manifesto for Agile Software Development was released for the reuse of software development tools and processes by businesses across the world in the early 2001. Agile methods began to spread rapidly to other fields of activity, including education, manufacturing, healthcare, engineering, and government. While Agile is not a formal management method, it has many similarities to management practice.
Agile is designed to build flexibility and trust in the relationship between the project manager and his or her team of software developers. The project manager is responsible for determining the technical requirements (also known as Scope statements) upon which the software will be based. The project manager is also responsible for managing the scope changes that may occur throughout the project. Since most projects last approximately five months, scope changes can be a significant concern. To this end, Agile methods use a process of frequent updates to the Scope statements in order to ensure that the changes do not change the focus of the project in a negative way.
In addition to managing the Scope statements, the project manager is also responsible for managing the prioritization of each sprint. This prioritization process involves determining what is most important to the project in terms of its technical aspects and integration with the business model. After the prioritization process is complete, the actual implementation of the code begins. During the sprint, the team completes the backlog items one at a time, in order to meet the deadline. Once all items have been implemented, the team moves on to the next sprint, and the cycle continues until all sprints have completed.
Agile methodologies encourage a collaborative development environment between the software engineers and the customer (the customer typically holds the “control” key during most Agile implementations). Each team member has an important role within the project; the software engineer ensures that the technology implementation meets the defined Scope statements, and the business stakeholder ensures that the software satisfies the business need. Communication between teams is lively and often confrontational. Since problems are resolved through a series of individual meetings and reviews, this friction is avoided.
Agile methods are designed to minimize potential risks to the project by implementing tests and requirements that have been validated. In most cases, these techniques to catch defects early so that they can be fixed before they cause a problem. By implementing quality testing techniques, developers catch bugs early before they are able to do any harm to the software or create a need for modifications. In addition, by requiring a simple change to the software before a release date, defects are identified before they become a problem.
Agile methodologies emphasize the use of iterations instead of the traditional design cycle. iterations refers to the length of time it takes to develop a new module or a significant change in the existing module. While iteration can be thought of as a measure of complexity, it is also used to describe a way of testing a system’s design. During each iteration of a release, the team completes a series of test cases. If the code successfully meets the specified requirements, it is released. If it does not, many reworks must be made in order to correct the problem.
There are a number of Agile processes that have contributed to the growth of this method of software development. One of these is the focus on testing early. The idea is to get rid of as much as possible unnecessary code, so that the only thing left is a well-complete, self-correcting product. Another important factor contributing to Agile development is the use of pull requests. A pull request, also known as a suffix, is a request initiated by a developer with a need to make changes to a part of a software program. Pull requests are very easy to review and often include an explicit description of what the change entails and why it is important to the continued success of the project.
