Question

Who must do all the work to make sure product backlog items conform to the definition of done

Answer 1

The Product owner is responsible for managing the product backlog. The scrum teams develop and maintain the records, and each scrum team includes its definition of done, as the functions and the targets of each team are different. The definition of done enables the maintenance of the quality and the criteria of the work and is used to analyse the quality and the complete work of a department.
