The Characteristics Of Agile Methodology

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.

A detailed analysis is needed before writing a user stories, and they are required to revised and revisited to check whether they are valid or not. It lost the details of performance requirement. The user stories do not define the user interaction details with the system. In the designing phase, there might be some of the gaps in the requirements like identifying some of the missing user stories, and mis-estimated stories. Some of the user stories are less relevant. The user stories lack with the level of detail and they are dependent on acceptance tests. They are difficult to put in a large and complex projects. While implementing the user stories in a project a frequent client interaction needed to be

One of the initial steps in researching a problem is to know exactly what the problem is and compose a problem statement that unambiguously identifies and defines the problem to research. Sekaran (2003) said, “No amount of good research can find solutions to the situation, if the critical issue or the problem to be studied is not clearly pinpointed” (p. 69). The area of research for this paper focuses on software development, in particular, the study of agile software development methodologies and if these methodologies are successful in delivering software on time, within budget, and includes the requested features.

On the other hand, Agile methodology is a development method that promotes teamwork and flexibility throughout the life-cycle; it is a development method that supports using a small, cross functional team to provide software frequently in small increments on a regular cycle. It implements regular contact with employees and is more flexible compared to the Waterfall Method. There are several different Agile software development methodologies like Crystal Methods, XP, Dynamic System Development Model (DSDM), and Scrum, all examples are focused on flexibility and focuses on keeping code simple, testing

customer. The first paper focus Agile itself and uses Extreme Programming as an example to show how

The two reports attempt to explore the advantages and disadvantages of utilizing agile software development over the waterfall model. As described in the reports, more and more organizations are considering the agile process approach versus the more traditional waterfall approach. The agile processes evolved in the late nineties and began to emerge as a primary software development method. While organizations are moving towards agile processes, it is unclear which process is the most used. Article A details a survey in which 153 developers were asked to describe their software development processes. The waterfall method was the most used software development method. However, Article B details that 36 out of 66 projects analyzed revolved around the agile methodology. Nonetheless, both articles conclude that one method or approach is not a best fit for all projects.

Agile Software Development: The iterative development strategy focuses on incremental delivery of usable software ("What is Agile Software Development?", 2017)

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.

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 [1].

During this research on agile development methodology, we have taken various Research papers, Magazines, online Journals and news articles into consideration. This research helped us to comprehend that all agile methods follow the four values and 12 principles of the Agile Manifesto. This paper explores the challenges open in agile systems development while adopting it in an organization. Additionally, we also analyzed the solutions to these challenges.

Unlike waterfall development methodology, agile foresees the documentation but is initially unwilling to adapt such as adding a lot new facets to the development model. Gabe, M. said, "Agile methodologies attempt to capture and use the dynamics of change inherent in software development in the development process itself rather than resisting the ever-present and quickly changing environment.". Demand of traditional methods complete and accurate requirement before the development; agile methods presume that change is strict, unavoidable and must be embraced throughout the cycle of product development. Cao, L. and Ramesh, B. believes individuals who fill those roles are much more important than the roles that people fill. Fowler also believes that each talented individual brings something unique to a team that are developing the system and disagrees with the application of engineering

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 methodology is an approach to project management and agile software methodology is not a one methodology but a set of methodologies which share common characteristics to achieve business goals. Before 1950’s project management have taken place in an informal way for many eras and after an ameliorating of formal project management methodologies began to be defined and swiftly spared through the industry rather than traditional methodologies. The traditional approach of project management identified a set of sequences of steps to be completed such as initiation, planning and design, execution and construction, monitoring and controlling and completion but not all projects will have every stage and some projects can be terminated before they reach completion. When it derived to IT industry in the past few years there’s been

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.
