Pessoal,
O texto comenta que o Scrum não tem uma reunião especial de Grooming. De fato, esta palavra nem aparece no Scrum Guide.
Porém, encontrei o trecho abaixo. Não é basicamente a mesma coisa?
Product Backlog refinement is the act of adding detail, estimates, and order to items in the Product Backlog. This is an ongoing process in which the Product Owner and the Development Team collaborate on the details of Product Backlog items. During Product Backlog refinement, items are reviewed and revised. The Scrum Team decides how and when refinement is done.
