Scrum vs. kanban

Scrum vs. kanban (by Dan Radigan)

(Excerpt)

Kanban and scrum share some of the same concepts but have very different approaches. They should not be confused with one another.

ScrumKanban
CadenceRegular fixed length sprints (ie, 2 weeks)Continuous flow
Release methodologyAt the end of each sprint if approved by the product ownerContinuous delivery or at the team’s discretion
RolesProduct owner, scrum master, development teamNo existing roles. Some teams enlist the help of an agile coach.
Key metricsVelocityCycle time
