Agile Development is an umbrella term for several iterative and incremental software development methodologies. The most popular agile methodologies include Scrum, Kanban, Scaled Agile Framework® (SAFe®), Lean Development and Extreme Programming (XP).
Agile software development refers to  software development methodologies centered round the idea of iterative development, where requirements and solutions evolve through collaboration between self-organizing cross-functional teams. The ultimate value in Agile development is that it enables teams to deliver value faster, with greater quality and predictability, and greater aptitude to respond to change. Scrum and Kanban are two of the most widely used Agile methodologies. Below are the most frequently asked questions around Agile and Scrum, answered by our experts.
Agile software development refers to a group of software development methodologies based on iterative development, where requirements and solutions evolve through collaboration between self-organizing cross-functional teams. Agile methods or Agile processes generally promote a disciplined project management process that encourages frequent inspection and adaptation, a leadership philosophy that encourages teamwork, self-organization and accountability, a set of engineering best practices intended to allow for rapid delivery of high-quality software, and a business approach that aligns development with customer needs and company goals. Agile development refers to any development process that is aligned with the concepts of the Agile Manifesto. The Manifesto was developed by a group fourteen leading figures in the software industry, and reflects their experience of what approaches do and do not work for software development.
While each of the agile methodologies is unique in its specific approach, they all share a common vision and core values (as per Agile Manifesto). They all fundamentally incorporate iteration and the continuous feedback that it provides to successively refine and deliver a software system. They all involve continuous planning, continuous testing, continuous integration, and other forms of continuous evolution of both the project and the software. They are all lightweight, especially compared to traditional waterfall-style processes, and inherently adaptable. And what is most important about agile methods is that they all focus on empowering people to collaborate and make decisions together quickly and effectively.
In the beginning, agile teams were primarily made up of developers. As these agile teams became more effective and efficient at producing software, it became clear that having Quality Assurance (QA) and Dev as separate teams was inefficient. Agile grew to encompass QA in order to increase the velocity of delivering software and now agile is once again growing to encompass the delivery and support members to extend agility from ideation to delivery.
The DevOps ideals extend agile development practices by further streamlining the movement of software change thru the build, validate, and deploy and delivery stages, while empowering cross-functional teams with full ownership of software applications – from design thru production support.
DevOps is an IT mindset that encourages communication, collaboration, integration and automation among software developers and IT operations in order to improve the speed and quality of delivering software.
DevOps teams focus on standardizing development environments and automating delivery processes to improve delivery predictability, efficiency, security and maintainability. The DevOps ideals provide developers more control of the production environment and a better understanding of the production infrastructure. DevOps encourages empowering teams with the autonomy to build, validate, deliver and support their own applications. With DevOps, nothing gets “thrown over the wall.”
