Agile Development
Description
- The agile software development
may be a practices approach for developing applications.
Agile methodology is described as an "iterative" and "incremental" approach. - The term agile management is applied to an iterative, incremental method of managing
the planning and build activities of engineering, information technology and other business areas that aimto supply new product or service developmentduring a highly flexible and interactive manner,supported the principles expressedwithin the Manifesto for Agile Software Development - Agile developers visualize the software as
a mixture of complex parts that interacts withone another instead of an out sized block of structure. - Actually in waterfall method, development team will get only single chance
to urge each phase(like design,development, testing etc) of a project. - Whereas in an agile methodology, these phases are continually revisited periodically
to know the project's progress and direction. - The "inspect-and-adapt" approach from Agile methodology , greatly reduces development cost and time
to plug the merchandise because here teams can develop the software while gathering changes in requirement. - The stakeholder can provide feed back to
the event teamto enhance the standard ofthe merchandise . - Agile development does save lot of resources which could have spent on something not needed anymore.
- It advocates adaptive planning, evolutionary development, early delivery, and continual improvement, and it encourages flexible responses
to vary . - Agile software development methods
are extensively used for development of software productsand a few of them use certain characteristics of software,like object technologies. - Agile software development paradigms
are often utilized in other areas of lifelike raising children. Its success in child developmentcould be founded on some basic management principles; communication, adaptation, and awareness.
Software development values
- Individuals and interactions over processes and tools
- Working software over comprehensive documentation
- Customer collaboration over contract negotiation
- Responding
to vary over followingan idea
Software development principles
There are twelve principles for agile software development.- Customer satisfaction by early and continuous delivery of valuable software.
- Welcome changing requirements, even in late development.
- Deliver working software frequently (weeks
instead of months) - Close, daily cooperation between business people and developers
- Projects are built around motivated individuals, who should be trusted
- Face-to-face conversation
is that the bestsort of communication (co-location) - Working software
is that the primary measure of progress - Sustainable development,
ready to maintaina continuing pace - Continuous attention to technical excellence and good design
- Simplicity—the art of maximizing
the quantity of labor not done—is essential - Best architectures, requirements,
and styles emerge from self-organizing teams - Regularly, the team reflects on
the way to becomesimpler , and adjusts accordingly
Adaptation cycle
- In agile software development team members
report back to one another what they did the previous day toward their team's iteration goal.
Development methods
- There are
wide selection methods of agile soft ware development. - It supports soft ware development life cycle.
- Some support activities for requirements specification and development (e.g., FDD), while some seek
to hide the complete development life cycle (e.g., DSDM, RUP) - Dynamic systems development method (DSDM) , Adaptive software development (ASD) ,Agile unified process (AUP) and Feature-driven development (FDD) are famous agile software development frameworks.
