# Agile

## Basic idea

A family of adaptive process methodologies that deliver value in short iterations, prioritise responding to change over following a plan, and treat customer collaboration as the source of truth.

## Key facts

* Four Agile Manifesto values: individuals > processes; working SW > docs; collaboration > contracts; responding to change > plan.
* Iterations (sprints): 1-4 weeks; produce shippable increments.
* Practices: daily stand-up, retrospective, backlog grooming, velocity tracking.
* SCRUM, XP, Kanban are common implementations.
* Focusses on adapting to change.
* Reliant on constant and regular feedback.
* Focuses on iterative outcomes delivering value as quickly as possible and collaboratively.
* Small manageable actions and activities.
* Involvement and ownership across the team.
* Customer focus over formalised sign offs.

## Pros

* Retains flexibilty while continually producing outcomes - less rework.
* Greater communication and engagement - increased buy in across the team of the end outcome.

  **Cons**
* Difficult to do without experience - especially an experienced Scrum master.
* Large projects - co-location a problem.
* Difficult to contract suppliers.
