An agile framework is a specific approach to software development based on the philosophy of the Agile Manifesto and Agile values. It involves people, tasks, and tools to plan, manage, collaborate, and execute work with an emphasis on agility, flexibility, iterative development, valuing people more than processes, and continuous feedback.
What is Agile? Agile is a set of principles that are used to improve the process of project management and software development. To put in simple terms, Agile helps teams in delivering value to customers quickly and effortlessly. The work provided, although small, is in usable increments.
Compared to traditional software engineering, agile software development mainly targets complex systems and product development with dynamic, non-deterministic and non-linear characteristics. Accurate estimates, stable plans, and predictions are often hard to get in early stages, and confidence in them is likely to be low.
