World War II often abbreviated to WWII or WW2, also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began. Agile software development Wikipedia. Agile software development describes a set of values and principles for software development under which requirements and solutions evolve through the collaborative effort of self organizing cross functional teams. It advocates adaptive planning, evolutionary development, early delivery, and continuous improvement, and it encourages rapid and flexible response to change. These principles support the definition and continuing evolution of many software development methods. The term agile sometimes written Agile4 was popularized by the Manifesto for agile software development,5 which defines those values and principles. Agile software development frameworks continue to evolve,3 two of the most widely used being Scrum and Kanban. HistoryeditIterative and incremental software development methods can be traced back to 1. Evolutionary project management89 and adaptive software development1. During the 1. 99.

Crystal Clear and extreme programming XP and from 1. Although these originated before the publication of the Manifesto for Agile Software Development, they are collectively referred to as agile software development methods. At the same time, similar changes were underway in manufacturing1. In 2. 00. 1, seventeen software developers met at the Snowbird resort in Utah to discuss these lightweight development methods, among others Jeff Sutherland, Ken Schwaber, and Alistair Cockburn. Together they published the Manifesto for Agile Software Development. In 2. Alistair Cockburn and Jim Highsmith wrote an addendum of project management principles, the Declaration of Interdependence,1. In 2. 00. 9, a movement by Robert C Martin wrote an extension of software development principles, the Software Craftsmanship Manifesto, to guide agile software development according to professional conduct and mastery. In 2. 01. 1 the Agile Alliance created the Guide to Agile Practices renamed the Agile Glossary in 2. The Manifesto for Agile Software DevelopmenteditBased on their combined experience of developing software and helping others do that, the seventeen signatories to the manifesto proclaimed that they value 5Individuals and Interactions over processes and tools. Working Software over comprehensive documentation. Customer Collaboration over contract negotiation. Responding to Change over following a plan. That is, while there is value in the items on the right, they value the items on the left more. Agile software development valueseditBy these terms, they meant 1. Individuals and interactionseditSelf organization and motivation are important, as are interactions like co location and pair programming. It is better to have a good team of developers who communicate and collaborate well, rather than a team of experts each operating in isolation.

Working softwareeditWorking software is more useful and welcome than just presenting documents to clients in meetings. It is better to comment inline with the code and to keep external documentation light, rather than heavy documents that take a lot of effort and quickly become outdated. Customer collaborationeditRequirements cannot be fully collected at the beginning of the software development cycle, so it is better to directly involve the paying customer and their end users, or a proxy for them so that detailed requirements can be progressively elaborated and adapted based on feedback. Responding to changeeditAgile software development methods are focused on quick responses to change and continuous development. Some of the authors formed the Agile Alliance, a non profit organization that promotes software development according to the manifestos values and principles. Introducing the manifesto on behalf of the Agile Alliance, Jim Highsmith said,The Agile movement is not anti methodology, in fact many of us want to restore credibility to the word methodology. We want to restore a balance. We embrace modeling, but not in order to file some diagram in a dusty corporate repository. We embrace documentation, but not hundreds of pages of never maintained and rarely used tomes. We plan, but recognize the limits of planning in a turbulent environment. Those who would brand proponents of XP or SCRUM or any of the other Agile Methodologies as hackers are ignorant of both the methodologies and the original definition of the term hacker. Jim Highsmith, History The Agile Manifesto1. Agile software development principleseditThe Manifesto for Agile Software Development is based on twelve principles 1. Customer satisfaction by early and continuous delivery of valuable software. Welcome changing requirements, even in late development. Working software is delivered frequently weeks rather than monthsClose, daily cooperation between business people and developers. Projects are built around motivated individuals, who should be trusted. Face to face conversation is the best form of communication co locationWorking software is the primary measure of progress. Sustainable development, able to maintain a constant pace. Continuous attention to technical excellence and good design. Simplicitythe art of maximizing the amount of work not doneis essential. Best architectures, requirements, and designs emerge from self organizing teams. Regularly, the team reflects on how to become more effective, and adjusts accordingly. OvervieweditPair programming, an agile development technique used by XP. Note information radiators in the background. Iterative, incremental and evolutionaryeditMost agile development methods break product development work into small increments that minimize the amount of up front planning and design. Iterations, or sprints, are short time frames timeboxes that typically last from one to four weeks. Each iteration involves a cross functional team working in all functions planning, analysis, design, coding, unit testing, and acceptance testing. At the end of the iteration a working product is demonstrated to stakeholders. This minimizes overall risk and allows the product to adapt to changes quickly. An iteration might not add enough functionality to warrant a market release, but the goal is to have an available release with minimal bugs at the end of each iteration. Multiple iterations might be required to release a product or new features. Working software is the primary measure of progress. Efficient and face to face communicationeditNo matter which development method is followed, every team should include a customer representative Product Owner in Scrum. This person is agreed by stakeholders to act on their behalf and makes a personal commitment to being available for developers to answer questions throughout the iteration. At the end of each iteration, stakeholders and the customer representative review progress and re evaluate priorities with a view to optimizing the return on investment ROI and ensuring alignment with customer needs and company goals. In agile software development, an information radiator is a normally large physical display located prominently near the development team, where passers by can see it. It presents an up to date summary of the product development status. A build light indicator may also be used to inform a team about the current status of their product development.
