explanatory Essay
1534 words
Introduction
Extreme programming roots evolved from Kent Beck and Ware Cunningham working together on a research group at Tektronix and the collaboration used on the project. (Larman, pg. 170) Extreme programming really became known during the Chrysler Comprehensive Compensation (C3) project where Kent Beck took personal risk in deciding which factor of programming to emphasize. As the methods taken became known as Extreme Programming (XP) the founders are often considered to be Ward Cunningham (the inventor), Kent Beck (the articulator), and Ron Jeffries (the realizer). (Unknown, Software Development Methodologies) The team worked together during the extent of the Chrysler Corporation project, which was the first large-scale use of XP. After this first project with the use of Extreme Programming Kent Beck published his first book Extreme Programming Explained and the use for this software development methodology gained increasing usage in the programming field.
Extreme Programming Principles and Values
The book Extreme Programming Explained written by Beck addressed that there are twelve practices to follow for XP. 1) The planning game: a high-level plan that explains and plans for the next iteration, 2) small release: frequent releases with evolutionary delivery, 3) metaphor: common vision, language usage, and terminology by all team members, 4) simple design: easy coding to make results work, 5) testing: automated tests with pass/fail results followed by implementation, 6) refactoring: enhance coding without affecting system behavior, 7) pair programming: having two developers working simultaneously at the same workstation sharing tasks and ideas, 8) collective ownership: anyone team member can change or improve coding at anyti...

- Extreme Programming Up Front Design Methodologiesanalytical essayExtreme Programming (XP) has spent the past decades under perpetual scrutiny by software developers fixated on up front design methodologies. The idea behind this is simple: if you want to make sure something is well built, you must design it well first, then put it together using reliable tools. For objects such as houses, cars, or tables, of which the design evolves gradually throughout decades, the methods of up front design suffice. Computer programs, on the other hand, are products often made for an industry that evolves at higher rates than any other. For this type of environment, more dynamic methods are required, which is why XP suits as a viable candidate. How design is altered from the traditional up front design method will be discussed.

This is because they are mostly linear and sequential, imposing a significant challenge when meeting changing user requirements. Volatility in user requirements has been a significant predicament until the discovery of agile project management methodologies such as scrum, Extreme programming, and Future driven development. Volatility originates from the urge of organizations to cope up with varying technological structure and market dynamics (Cockburn, 2002). The conventional software development methods include sequential and linear processes cannot meet changing user requirements, but have shown their efficacy in meeting consistent requirements. These challenges have increased sophistication and inter-reliance of systems subjecting the usual methods to extinction. The concept of agile software development refers to an iterative method employed when determining the necessities of software developments projects with regard to flexibility and intensified interaction. Apparently, agile software development methodologies are more advantageous than conventional methods. The supporting facts to this statement reveal why scrum and XP are increasing emerging as preferable techniques. The main purpose of this is to discuss the criteria used to support the claim that agile software development methodologies are a superior design method. This paper affirms that agile software development methodologies are more effective than the conventional project methodologies because they are simple, iterative and incremental, resulting to efficacy in meeting changing customer requir...

Once these fundamental flaws were found, Alan MacCormack of Harvard Business School described three principles that could be used to replace the traditional project management methods. These principles were focused on software development. The early and continuous release of code, the idea of daily code builds with fast turnaround, and the idea of having a deeply skilled team were these principles (techrepublic.com, 2009). These ideas created by Alan MacCormack are what are cited to have created the relatively recent movement to agile project management which focuses not on formality, but on fast, lean, efficient and iterative management

Overview Agile software development is a group of software development methods based on iterative and incremental development, where requirements and solutions evolve through collaboration between self-organizing, cross-functional teams. It promotes adaptive planning, evolutionary development and delivery, a time-boxed iterative approach, and encourages rapid and flexible response to change. Agile development is chosen when the requirements are not clear. This is the reason that it is chosen for the projects where the rate of risk is high.
In this essay, the author
- Explains that agile development alerts developers before time that the requirements of the project are being misinterpreted.
- Explains that software size is easy to measure and it can also be measured through function point analysis. agile development is suitable for projects of small sizes where projects are completed in months, not years.
- Explains that the type of the customer or the end user is very important when it is concerned with types of end users. sequential models can be the best approach but agile method is good for unpredictable or technology ignorant customers.
- Explains that agile development is best when the time of the project is short. iterations are done in short time and are then modified and improved over the passage of time.
- Explains that resources are important factors, which decide the success of the project. sequential approach will be good if resources allocated to the projects are sufficient otherwise iterative and incremental approach is good.
- Explains the importance of team collaboration and coordination in the selection of the methodology. if team is not fully integrated and close to each other, it is good to choose agile methodologies.
