Extreme programming (XP) is one of the most important Agile methodologies for software development. It is used to improve software quality and responsiveness to customer requests. This article will teach you everything you need to know about extreme programming, allowing you to take advantage of it.
Anyone who uses a laptop or mobile device on a regular basis must be familiar with what programmers do. Since companies and customers are continually looking for new software, developers create new products, while programmers oversee the code required to make the software work.
The concept of extreme programming is gaining much more acceptance in the software world since it makes the coding process efficient and effective. This blog serves as the introduction to Extreme Programming (XP) that the market will need. However, anyone interested in discovering what this concept can offer them should read this blog.
|What is Extreme Programming -Table of Contents|
Extreme Programming (XP) is an agile software development framework that aims to produce higher-quality software with changing requirements. Furthermore, XP is most explicit in terms of the right engineering practices for software development.
XP is built upon values, principles, and practices that allow small to mid-sized teams to produce high-quality software and adapt to evolving and changing requirements.
XP was introduced by Ken Beck in the 90s with the objective to find new approaches to writing high-quality software fastly and to adapt to changing customers’ needs.
To get a clear understanding of these practices, we’ll start by describing how XP’s work and the roles engaged in the process.

In contrast to other approaches, XP is very opinionated in engineering practices. In addition to practices, XP is based on values and principles.
Values: For teams, values provide direction. They serve as a high-level "north star" to direct your choices. Values, however, are too nebulous and vague to provide precise instruction. Saying that you appreciate the communication, for instance, can have a variety of effects.
Practices: In some respects, practices are accountable to values. They define the specifics of what to do clearly, and practically. Teams can hold one another accountable to the ideals through practices. For example, the use of Informative Workspaces encourages open and straightforward communication.
Principles: They are industry-specific guidelines that bridge the gap between ideals and practices.
Next, let’s understand XP values, principles, and practices in-depth, and how they work together to create extreme programming.

Values provide direction to the team in making high-level decisions.
Unlike values, principles are more grounded, practical, and concrete ideas. XP principles specify what teams must do in detail and give team members a way to hold one another responsible for upholding the principles. These are the five guidelines:
Initially, there were twelve practices of extreme programming, but they have been honed and reduced through time. This list of practices is the most current.
The benefits of extreme programming are as follows:
Slipped schedules − and achievable development cycles ensure timely deliveries.
Project cancellation − Focus on continuous customer involvement ensures transparency with the customer and immediate resolution of any issues.
Increase in the costs due to modifications - Extensive and ongoing testing makes sure the changes do not break the existing functionality. A running working system always ensures sufficient time for accommodating changes such that the current operations are not affected.
Production and post-delivery defects - Emphasis is on − the unit tests to detect and fix the defects early.
Business changes − Changes are considered to be inevitable and are accommodated at any point in time.
Staff turnover − Intensive team collaboration ensures enthusiasm and goodwill. The cohesion of multi-disciplines fosters team spirit.
Even an experienced extreme programming team shouldn't rely on fixed roles, new teams can profit from them by keeping members inside their designated areas of responsibility until the method is no longer required. The four most typical XP roles are as follows:
Having technical knowledge and XP practices can be difficult. For programmers who aren't accustomed to them, some of the techniques may seem strange.
Teams can start with XP by implementing one core practice at a time. Determine your next objective to help you decide where to start. Select a method that supports that objective.
Start with pair programming and TDD, for instance, if your team needs to develop a sense of trust in the code and other team members. Adopt communal code ownership if you want to get rid of the danger brought on by relying too heavily on particular team members.

Scrum is a methodology that helps teams develop complex projects in an adaptive way. Scrum doesn't set any guidelines for how developers must accomplish their work. While XP focuses on best programming practices.
Furthermore, programming is undoubtedly at the core of XP. On the other hand, Scrum may be utilized on any project that benefits from an iterative approach.
XP allows modifications to its components. Teams are free to modify the tasks to meet their specific requirements. On the other hand, the Scrum Guide is categorical that "implementing some portions of Scrum is possible, but the result is not Scrum."
Scrum is a framework that must be completed with work-related methodologies and practices.
Therefore, using XP and Scrum together is feasible and highly recommended.
Extreme Programming involves the client in the software development process, just like other Agile methodologies do. It does not, however, use any intermediaries to connect the team and the customer, unlike other Agile methodologies. On XP projects, all of the work is divided into smaller portions.
In the 1990s, Kent Black tried to create a more efficient method of software development while handling a project at DaimlerChrysler. This was the initial emergence of extreme programming (XP). His innovative approach eventually earned the name "Extreme Programming Methodology," and it was effective.
The main characteristics of extreme programming (XP) include:
The extreme programming lifecycle is divided into 6 phases
The popularity of agility concepts is rising as they prove to be effective. Extreme programming offers a lot of useful methods that can assist with software development, even though it is not the most common methodology. These techniques are worth considering for usage in your projects.
