Agile focuses on adaptive, simultaneous workflows. Agile methods break projects into smaller, iterative periods. Kanban is primarily concerned with process improvements. Scrum is concerned with getting more work done faster.

Sprint In product development, a sprint is a set period of time during which specific work has to be completed and made ready for review. ... Scrum Scrum, the most popular agile framework in software development, is an iterative approach that has at its core the sprint — the scrum term for iteration.

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. ... Scrum and Kanban are two of the most widely used Agile methodologies.

In an agile approach, iteration occurs across activities. Therefore, the requirements and the design are developed together, rather than separately. A plan-driven software process not necessarily waterfall model – plan- driven, incremental development and delivery is possible.

Definition. Extreme Programming (XP) is an agile software development framework that aims to produce higher quality software, and higher quality of life for the development team. XP is the most specific of the agile frameworks regarding appropriate engineering practices for software development.

The main difference between traditional and agile approaches is the sequence of project phases – requirements gathering, planning, design, development, testing and UAT. In traditional development methodologies, the sequence of the phases in which the project is developed is linear where as in Agile, it is iterative.

Agile is a continuous iteration of development and testing in the software development process whereas Scrum is an Agile process to focus on delivering the business value in the shortest time. Agile methodology delivers the software on a regular basis for feedback while Scrum delivers the software after each sprint.

Agile is the root of project management methodologies such as Scrum (consists of sprints) and others. So it is not a programming language neither Scrum. ... Agile is a philosophy and practice of software development. You can use any language you like.

In the Agile model, end date for an iteration is fixed, it cannot be changed. The development team may have to decide to reduce the delivered functionality to complete that iteration on time. In the Incremental development model, there is no fixed time to complete the next iteration.

On an agile team, stories are something the team can commit to finish within a one or two-week sprint. Oftentimes, developers would work on dozens of stories a month. Epics, in contrast, are few in number and take longer to complete. Teams often have two or three epics they work to complete each quarter.

If it's decided that agile is the most appropriate development methodology to use, then the three key things that will enable the project to be a success are: collaboration, constant focus on business value, and appropriate level of quality. We'll discuss those elements now…

However, Agile does not condone little or no documentation—Agile encourages the “right” documentation. Agile encourages “just enough” documentation as is required for the project. This documentation can be in the form of flip-chart notes or writing on a white board.

Extreme Programming and Agile Like other Agile methodologies, Extreme Programming involves the client into the process of software development. However, unlike other Agile approaches it has no intermediaries between the customer and the team. All the work on XP projects is subdivided into small sections.

Fundamentally, DevOps brings together two large siloed teams together to allow for quicker software releases while Agile is focused on getting smaller teams to collaborate with each other so it can react quickly to the ever-changing consumer needs.

Advantages of Agile over Waterfall are: Agile techniques virtually eliminate the chances of absolute project failure. Agile means always having a working product which is being built incrementally right from the very first sprint, so that projects do not fail completely.
