The Definition of READY | Xebia Blog
Defining READY
READY is defined by the Definition of READY. It is similar to the Definition of DONE, but with the following differences. Whereas with the Definition of DONE the "supplier" is the Team and the "client" is the Product Owner, it's the other way around with the Definition of READY: the Team is the "client" and the Product Owner is the "supplier". Even though I will detail the Definition of READY later, in the end it boils down to one statement: READY is when the team says: "Ah, we get it".
Even though you can put any precondition in the Definition of READY, the need for a good backlog overshadows all other considerations, so you'll definitely need to address two items: readiness of User Stories, and readiness of the Backlog.
