What are the differences between agile and scrum project management appoaches?
Could somebody explain the difference between agile and scrum? I would appreciate if someone can comment with a practical scenario to help me better understand how I would use both when managing big projects!
Agile describes a set of guiding principles that uses an iterative approach for software development, while Scrum is a specific set of rules that are to be followed while practicing Agile software development.
Agile management represents various o software-development methodologies that have been influenced by iterative and incremental development, which includes Extreme Programming (XP), Rational Unified Process (RUP), Scrum, and others. Agile process or methods provide an environment where there is constant evolution in requirements and evolution as a result of the collaboration between self-organizing cross-functional teams. Agile methodologies foster a disciplined project-management approach that encourages a set of best practices, allowing rapid delivery of high-quality software and enhancing a business approach, which aligns development with customer needs. The Agile methodologies stand in contrast to the traditional waterfall methodology, where all the requirements are initially analyzed and documented before the development begins. In the Agile approach, requirements are like the actual software-development advances within each iteration. This approach provides flexibility in accommodating changes in the requirements and priorities of the business.
The Agile development process aligns with the concepts of Agile Manifesto. Also known as Manifesto for Agile Software Development, the Agile Manifesto is a formal declaration of 4 key values and 12 principles supporting an iterative approach to software development. The Agile development methodology enables assessment of project direction throughout the development lifecycle. This is achieved through regular iterations, and when the revaluation is done at every iteration, it greatly reduces the development costs and time. Agile helps the companies to build the right product.
Scrum, on the other hand, is a subset of Agile. A Scrum is a simple and flexible Agile methodology for software development. The Scrum is not a technique or a process but a lightweight and simple framework to address complex problems of a project and deliver a high-value product creatively.
