AGILE The AGILE Argument Jesse Allen 5/7/2015 CIS280 DEA 14-55 This paper will take a in depth look at what makes AGILE “AGILE”, including the history, uses, and arguments for and against its use. Contents Introduction 2 History 2 The Goal 2 The Evolution of Agile 5 Uses 7 Pros 8 Cons 9 Conclusion 10 Works Cited 11 Introduction The idea behind Agile is to put people before processes, to deliver working software versus mountains of documentation, to collaborate with clients rather than negotiate contracts, and lastly to be agile rather than rigidly following a plan (History: The Agile Manifesto).

The Goal The Goal was not to create an anti-methodology but rather create a methodology that achieved balance. Prior to the formation of the Agile methodology many other methodologies existed, many of which still exist. One such methodology is the Waterfall methodology. The Waterfall approach is a very linear (and not agile) style of development. In Waterfall development there are several steps that take place starting with the conception, followed by the initiation, then the analysis, which is followed by design, then construction. After the construction is complete the process moves into testing, implementation and then lastly maintenance. One downside to this sequential flow of processes is that once a task is completed there is no going back. If the requirements where wrong or changed the entire project is destined to fail. In contrast, the very nature of Agile development is to be able to quickly adapt to changes in requirements (Agile & Waterfall Methodologies). The Agile Manifesto outlines twelve principles that make Agile “Agile” • Our highest priority is to satisfy the customer through early and continuous delivery of valuable software (History: The Agile Manifesto).. This is a key distinction between traditional and Agile methodologies. Traditional methods deliver an end product with all desired features at time of completion. If
“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.
Agile techniques should be used to solve the current issues faced by the company as agile techniques normally being used by the software industry help the business to act in response under the unpredictable situations faced. In Agile methodologies opportunities are been provided to evaluate whether the project is under the direction all through its development cycle. All this is being accomplished with the help of regular tempo kept in work, and the teams must show a product which is having the desired potential.
In 2001 a group of thought leaders recognized the need for common set of values and principles that represent Agile Vision, as traditional development methodology was failing too often and they came up with Agile Manifesto that emphasizes four important Agile

Ultimately, while agile software engineering certainly represented a challenge to the well-established waterfall method, it didn't entirely throw away every element of the old guard (Cockburn, 2001). The new concept was actually based on the idea that individuals could better govern themselves, and could more effectively use their creativity within an overall framework if they were given some freedom to interact on a day-to-day level, facing problem-solving within the
The Agile methodology (AM) for software development is an iterative system characterized by cycles of development, testing, and stakeholder feedback. According to Ferreira and Cohen, the Agile methodology has the following five characteristics (50):
Compared to the agile, another famous software development mode called waterfall is driven by technique documents and this mode require the team to write a lot of requirement documents containing all the requirements to a certain software. It is written to allow people to understand what software should do. So the developers will develop the functions of software according to the documents strictly. But the agile software development just focuses on the necessary document. It is avoid taking a lot of time to write the requirement documents. Its opinion is that the face to face communication between the human is the most important thing. So the agile think the human is
Software development is one of the highest demands in all over the world. We use software development techniques to solve the problems and to satisfy customers. Agile software development is a conceptual framework for software; it is also a group of software development methods based on iterative development. In 2001, agile software development was created by seventeen people with a desire to find alternative approaches to software development. The most important thing about agile methods are team work, conveying information to the team, face to face conversation, and satisfy the customer. There are various methodologies but I am going to describe the most popular ones.
The agile software methodology uses teams that are self-organized and can develop incremental periods of work rather than working for long periods of time. Having face-to-face collaboration is preferable over written documentation. It tends to be more adhesive and produces better products in the end. Having the ability to change the direction/plan at any point during the project is possible. If change is not accommodated throughout the project, the team will not have set realistic expectations and it will be difficult to meet the anticipated deadline time period. The agile methodologies value the individual and interactions between the team over processes and other tools. When the agile software development approach is used, the team is
These are some reason that traditional processes replace agile processes mainly in small and simple projects. This is happening because of traditional methods’ limitations and deficiencies, which includes a slow adaptation to business requirements changes, and a tendency to go over budget and as well as behind schedule. The traditional methods also lack in providing improvements in simplicity, productivity and reliability phenomena’s. Despite of these limitations, traditional methods are widely used by many software developers in projects. Traditional methods are capable to provide high assurance, predictability, and stability and their nature is structural, straightforward, and methodological. Agile processes mainly focus on incremental as well as iterative development. Also, frequent deliveries after each sprints and customer collaboration are key element of Agile. Agile process has many advantage such as short lifecycle, low bug-rate, high customer satisfaction, and fast adaptation to changing requirements.
Agile methodologies provide businesses with a way to quickly react to changes in their environment. By delivering small portions of code over the course of a few weeks, developers can provide end-users with useable functionality on an ongoing basis as they move closer to the goal of providing the complete software. By being more reactive to changes, such as new requirements or changes in priority, agile allows development teams to be able to be more responsive and to provide customers with revised applications that are based on feedback that they have previously provided. Agile models, such as XP, are geared towards cost savings
The phrase agile refers to a software development methodology which promotes a project environment for adaptation, rapid delivery and client focus, self-organization and team work. Agile software development methodology is a conceptual framework for
Agile movement gives alternatives to the normal way of project management. The Agile way is usually used in software development to assist businesses to react to the unpredictability.
Begin agile, enable teams to deliver the most value; in less time and with least amount of headaches.
Agile Software Development is a set of principles that have revolutionized the software development industry. They "seek alternatives to traditional project management" acting as "an alternative to waterfall, or traditional sequential development." (The Agile Movement, agilemethodology.org) It is thought that Agile came to be with the introduction of the Agile Manifesto, but their origination dates back much further.
