The agile manifesto proposes that a “team reflects on how to become more effective”. Agile retrospectives can be used to inspect and adapt the way of working. They help teams to become agile by deploying agile practices in an effective way and continuously learning and improve themselves. This talk explains the “what” and “why” of retrospectives and the business value and benefits that they can bring. Examples will be given of exercises that you can use to facilitate retrospectives, supported with advice for introducing and improving retrospectives. It is based on the successful book Getting Value out of Agile Retrospectives which is published on InfoQ, Amazon, Leanpub. Retrospectives are a great way for teams to improve their way of working, to become more agile and lean. Getting actions out of a retrospective that are doable, and getting them done helps teams to improve continuously and deliver more value to their customers.
