Extreme 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 …show more content…
“reveals all the intentions”, on the other hand, makes sense under the following train of thought: if something is simple, it is easy to understand, and therefore all or most intentions are clear to the observer. “does not have duplicated code” seems to make things easy to understand, but may not necessarily simplify a program. Finally, “has the fewest number of classes or methods” seems to be the most pertinent to the concept of simplicity. If a system consists of less functional elements than another one but holds the same product, it could be considered simpler. Following this definition, a system that contains the least amount of functional elements than any other, but holds the same product, could be considered simplest. Other than a few definitions of simplicity, Fowler mentions YAGNI, an acronym he claims is one of the “...greatest rallying cries in XP...” (Fowler). It stands for “You Aren't Going to Need it” (Fowler). The idea is summed up by Fowler as a method to only program what is currently needed for the project. This is supposed to allow easy changes to be made when needed. An example: consider the scenario where a calculator is being programmed. Its design incorporates 'addition' and 'multiplication'. Whilst implementing 'addition', it may seem logical to add some of the 'multiplication' features to reduce the amount of future work. Suddenly the client decides to replace 'multiplication' with 'division'. 'multiplication' now has to be removed or
Like any other complex structure, software must be built on a solid foundation. Failing to see the big picture or consider key scenarios, failing to design for common problems, or failing to appreciate the long term consequences of key decisions can put your application at risk. Modern tools and platforms help to simplify the task of building applications, but they do not replace the need to design your application carefully, based on your specific scenarios and requirements. The risks exposed by poor architecture include software that is unstable, is unable to support existing or future business requirements, or is difficult to deploy or manage in a production environment. Software architecture must be distinguished from lower-level design (e.g., design of component internals and algorithms) and implementation.
This isn’t necessarily about simplicity, but the fact that add-ons that appear good but do not integrate with the system are considered unimportant and are left out. If a system is full of good ideas but those ideas are not entirely useful to it then the system is recreated with a different set of ideas. He also goes on to talk about architects and implementers. Architects represent the user’s agent or a “complete and detailed specification of the user interface.” (45) An architect tells what will happen in the system. An implementer focuses on the how-to as in what goes on inside the
He chuckled at my change in behavior. “Very well. It was many years ago but yes, I did grow up here. But don’t confuse that with being part of a family. It was purely nonphysical.”
“Simplicity, simplicity, simplicity” said Thoreau was the underlying concept of Transcendentalism (1029). It’s focus or idea was to release oneself to be free to be who you really are without judgment, fear, or regrets. In many ways if the world would simplify itself, it would be a better place, however, people are not simple at all. Ralph Waldo Emerson and his disciples were inspired to change the world, but also to inspire each generation to create and express themselves. Although they wanted to touch the minds around them, they did not want to be imitated has awkwardly as that seems. They wanted people to see beyond what lies in front of their eyes. People need to have the ambition to pursue what they have deep inside. Transcendentalism pushes one to create, to imagine, have passion, have determination even if you fail, and above all to be true to yourself. Is it nonsense or is it individualistic concepts everyone should live by?
Agile processes do not devote much time up front to formal system specifications, but rather relies on continuous communication with the customer throughout the development process. The process accounts for the fact that needs often change or cannot be fully developed early on and is flexible to this. (+)
Introduction to Agile Methods by Hayes and Andrews gives detailed-oriented information about different aspects of agile methods like why there is a need for new software development processes and pitfalls of traditionally methodologies and how this lead to emergence of agile methods. They describe various existing agile methods but describes only one in great detailed – Extreme Programming(XP). They define Extreme Programming as agile, adaptive software methodology having well defined values - Communication, Simplicity, Feedback, and Courage. Failing in achieving this values will result in failing Extreme Programming. Extreme Programming is used only when you have complete understanding of the business and requirements. Extreme Programming follow a series of iteration to deliver the final project. Initially the story heard from the customer is broken down into smaller stories such that the developers can assign time to develop that stories and then its deliver to the customers for feedback. Coach plays a vital role in Extreme Programming. Afterwards Hayes and Andrews describe how XP differs from traditional methodologies. They also explain the common misconception about Extreme Programming is spread around the world. There are only fewer companies in the world that uses Extreme Programming because people are afraid of changing to new methods.

“Agile” was first introduced in 2001, by a team of software engineers looking to improve their adaptiveness and responsiveness to ever-changing requirements. Not knowing where to begin, the team began by formulating principles, which they would use to guide their new development process. Which, in turn, lead to the creation of the Agile Manifesto, and thus a new methodology was born.
Simplicity is not just a noble character, but also an asset. It is a ladder to success. It makes one an object of admiration which cannot be bought with money or lived easily. It is not as easy as it is called. When you are without spot, you 're not only a figure for admiration, but also a focus for jealousy and hatred; and in no distant time, so many unwanted notes would be filed against you. You need not be weary or worry because I have an assurance for you. In style, in character, in manner, in all things, the supreme excellence is simplicity.
Project Management Office (PMO) and Agile method are highly reputable terms in many organizations, especially in their IT projects. The PMO is a group of people or committee within an organization that is responsible to define and maintain standards and practices for traditional project management. The ultimate objective for the PMO is to gain the benefits that are derived from applying Project Management (PM) methods, practices and policies. Thus, the PMO over time will become the origin for documentation, guidance and metrics regarding to any practices that are involved in managing projects within the organization, as well as it will be the communication channel that
This figure represents the relationship that forms under the extreme programming methods. I believe this exemplifies the planning phase and the team deliverables that go into consideration. The project works on five main operational principles that are based on the core values which are assume simplicity, rapid feedback, incremental change, embrace the change, and quality work.
The paper compares two Agile methodologies known as Extreme programming (XP) and Feature-driven development (FDD) and explores the effects each has on games systems.
Agile is an iterative and incremental (evolutionary) approach to software development which is performed in a highly collaborative manner by self-organizing teams within an effective governance framework, with "just enough" ceremony, that produces high quality solutions, in a cost effective and timely manner which meets the changing needs of its stakeholders .
Yet another method is extreme programming (XP). It is also a software development method which improves software quality and responsiveness to changing customer requirement (extreme). This program has proved very successful at many companies. It is successful because it focuses on customer satisfaction. Extreme programming emphasizes teamwork. In this program, managers, customers and developers are all equal partners in a team. Extreme programing improves a software project in different ways which are communication, simplicity, feedback, respect and courage. In this method, programmers constantly communicate with their customers. They keep their design simple and clean. They get feedback by testing their software and deliver the system to the customer as soon as possible and implement changes as suggested. Every team member involvement is essential for the success of the program. With this foundation extreme programmers are able to courageously respond to changing requirement and technology (Extreme Programming).
