The delivery of a product with obsolete requirements, not meeting the customer’s expectations. There is a requirement of a rigorous change process that involves a change control board that may even push the changes to later releases.
Resistance to the changes at a later stage of development. However, if the requirements are to be changed later, then following is usually noticed − Gather requirements before development starts.

The following trends are observed in software engineering − Progress is constant, sustainable, and predictable emphasizing transparency. The whole-team approach avoids delays and wait times.įrequent and continuous deliveries ensure quick feedback that in in turn enable the team align to the requirements.Ĭollaboration facilitates combining different perspectives timely in implementation, defect fixes and accommodating changes. It fosters shared responsibility and accountability.įacilitates effective communication and continuous collaboration. Characteristics of Agilityįollowing are the characteristics of Agility −Īgility in Agile Software Development focuses on the culture of the whole team with multi-discipline, cross-functional teams that are empowered and selforganizing. That is, while there is value in the items on the right, we value the items on the left more. Responding to change over following a plan.
Working software over comprehensive documentation.Ĭustomer collaboration over contract negotiation. Individuals and interactions over processes and tools.
Through this work, we have come to value − We are uncovering better ways of developing software by doing it and helping others do it. In software development, the term ‘agile’ is adapted to mean ‘the ability to respond to changes − changes from Requirements, Technology and People.’ Agile ManifestoĪ team of software developers published the Agile Manifesto in 2001, highlighting the importance of the development team, accommodating changing requirements and customer involvement. Business‘agililty’ means that a company is always in a position to take account of the market changes. In business, ‘agile’ is used for describing ways of planning and doing work wherein it is understood that making changes as needed is an important part of the job.
