Agile And Agile Software Development

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.

The Agile Methodology Principles makes the development much faster because the primary importance is given to the customer satisfaction and continuously delivers product. Even though requirements change at the ending phase the product is developed. The Agile development insist the self-organizing team which can create requirements, best architectures, best models. The Agile development promotes a distinct way of thinking to build things and methods to deliver continuous improvement of product. It facilitates to make best practices and decisions together. It a development to promote the adaptive planning, continuous improvement, evolutionary development and delivery, and required time to complete work. It encourages for rapid response to change in the whole development cycle. The project team prefers agile development to move in a creative and quick way. The project progress also depends on working software and project environment and support is provided and built by the individuals. They promote the sustainable environment. Constant attention is provided to the technical excellence and best models are given by the agile methodology. This principle helps the project team members

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.

Agile values Individuals and Interactions over Processes and Tools. Agile emphasizes the importance of individuals having interactions and engaging in collaborative thinking for software design and development.

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)

Waterfall life cycle model and Agile methodology are the methods to implement and develop software. The initial methodology used by company is Waterfall methodology consists of sequential steps for the designing of software. One can predict cost, duration and requirements of the project in this method. This method is primarily used when organization knows what the end product of the project is. Proper planning is required before the start of the project.

Among the various approaches adopted in project management is Agile Methodology, one that is mentioned frequently among experts and considered as one of the key approaches adopted in organizations. As pointed out by Stare (2013), Agile Methodology can be described as a particular way that is embraced in the management of projects and teams in Information and Technology among other fields. There are various practices associated with the Agile Methodology and some of them include the ability to assume simplicity, creation of documentation based on value, enabling rapid feedback to all stakeholders, and embracing change among others practices. Since its emergence in project management, various research studies have been conducted in a bid to explore the possibilities of using the Agile Methodology in other industries that are not specifically meant for software development. Given the fact that corporations are

There are many different methodologies when it comes down to software development. Some methods may be too complicated for a small business to use. Agile development is a methodology that works extremely well for small businesses, and focuses on the strength of people-centric viewpoint and collaboration. Some benefits of agile development are increased productivity, expanded test coverage, improved quality/fewer defects, and higher customer satisfaction. Some challenges in

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].

and new demands from users (Uikey & Suman, 2012). The SDLC focuses on the prime

Agile methodology is a software development lifecycle which designed to produce faster development and high quality results compared with the traditional lifecycle. The Agile method focuses on incremental and iterative development where requirements, specifications, design, implementation, and testing continue throughout the project lifecycle (Nanthaamornphong, Morris, Rouson & Michelsen, 2013). Agile software development methods enable software developer to be more flexible and responsive to the changing environments and customer demands. However, Agile adoption comes with special challenges and fundamental organizational changes are necessary for successful outcome.

Agile is the management of incremental software development across cross functional teams. Learned from years of successes and failures, the agile philosophy centers on software development with an importance with self-organization, motivation, in addition to daily team interaction. It means being able to present working software instead of slides and documentation. Agile encourages customer collaboration throughout the entire process to allow developers to respond to change in a timely manner. The agile development process can be implemented by different developmental processes and is comprised of several key principles. With personal experience of the outcome of correct agile implementation; agile can have the opposite effect without

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.

It’s very collaborative process, for a team following the agile methodology for developing an application, everybody should be collaborating with each other at every stage of developing the application, these are the key points about agile methodology, with the agile methodology the changes can be made without getting the entire program rewritten, this approach not only reduced over heads it also helps in upgrading of programs, the other advantage of agile methodology it ensures that bugs are caught and eliminated in the development of each cycle and the project is tested every time. There are different types of agile methodologies they are XP (extreme process), Scrum, Lean software development, AUP (agile unified process), FDD (feature driven development) all these agile methodologies are customer driven and are light weight approaches, they are collocated and collaborative for developers, in the view of customers this method is dedicated, knowledgeable ,collocated, representative and empowered. Rapid changes in the requirement and need for new requirements, architecture is designed for only current requirements and architecture may change accordingly with the change in requirements. Refactoring is inexpensive, so n number of changes can be made as it doesn’t affect the budget, this process is best suited for smaller teams and products, and primary objective of
