Extreme Programming (XP) and Agile Methodology
Differences
Extreme Programming (XP), as an agile software development model, focuses on producing higher quality software and the development team's higher quality of life. XP is the most specific elegant model for the best engineering practices for developing software. XP consists of rules that hold to Agile's values and principles. It is a distinct method, whereas Agile is a classification. On the other hand, agile methodology aims to enhance software efficiency. This methodology has various Agile methods such as Scrum, crystal, and lean development, unlike XP, which has only one way (Erickson et al., XXXXXXXXXXWhile these differences are detailed, Scrum is an XP's subset. Most Scrum teams increase their process by adding more XP practices such as Pair Programming, Acceptance Testing, and Continuous Integration, mainly Test-Driven Development.
XP involves the client in the process of developing software. Unlike Agile methods, XP lacks intermediaries between the team and customer (Erickson et al., XXXXXXXXXXAll the XP project work is subdivided into small sections.
An Organization Using the Methods
Ford Motor uses XP as a companywide commitment to enhancing Ford's "fitness." The company has redesigned its business by recognizing the rapid pace of change and innovation within the automobile industry. The organization achieved 10% improvement, although it aimed at 10x improvement (Sohaib et al XXXXXXXXXXApple utilizes agile methods in its change programs, commonly known as agile transformations. The company has used agile methods in its small multidisciplinary teams to deliver fast, experimental, and iterative results.
Since Apple operates in a rapidly changing technological environment, agile methodology has helped it improve flexibility and leverage a quicker approach of bringing incremental innovations and new services and products in the market. For instance, agile methodology has facilitated Apple's OS development teams to "build different" to avoid bugs that crept into iOS 13. Previously, the absence of agile methodology allowed bugs to sneak into the operating system unnoticed, an incident that compelled Apple to change its approach for iOS 14 ("Azul") development, thereby adopting agile methodology.
this is the second one .
Extreme Programming (XP) is a revolutionary software development technique that opposes several premises adopted by traditional software engineering methods. XP consists of a series of practices and rules that allow developers to develop high-quality software in a dynamic and very agile way.
XP is built on values, principles, and practices, and its goal is to enable small and medium-sized teams to produce high-quality software and adapt to evolving and changing requirements.
What differentiates XP from other agile methodologies is that XP emphasizes the technical aspects of software development. Extreme programming is accurate about how engineers work, as following engineering practices allow teams to provide high-quality code at a sustainable pace.
Agile methodology is a set of techniques and practices for project management that offers more speed, efficiency, and flexibility. Its initial goal was to streamline software development, but these methods have extrapolated the technology sector and today revolutionize the management of companies in all areas. The agile methodology makes the processes simpler, more dynamic, and iterative, from the conception of the idea to the final product.
Agile methodology is similar to XP in focusing on an incremental development process and timely delivery of working software. However, there is less emphasis on team coding and more emphasis on limiting the scope of the project.
Ford Motor, Chrysler, and IBM are companies that use Extreme Programming (XP). The goal is to make the code-writing process less random, get the software to customers more quickly, and eliminate the inevitable onslaught of bugs discovered during the traditional integration phases. More and more companies may begin turning to Extreme Programming, especially during the current economic slowdown, as they look for new ways to improve efficiency and stamp out defects in software long before they appear in the final product.
Ford Motor Company VCAPS system – Spent four unsuccessful years trying to build the Vehicle Cost and Profit System using traditional waterfall methodology – XP developers successfully implemented that system in less than a year using Extreme Programming.
Cisco, Apple, Microsoft, and Procter & Gamble are companies that use Agile Methodology. The benefits of Agile are the ability to improve flexibility amid a rapidly changing environment.
Cisco engineers have put thefull principles of Agile development into practice and worked closely with customers to create more valuable software through accelerated innovation and products that meet genuine market needs. Despite the agile promise, its benefits do not come automatically.
