True or False: Disciplined Agile roles cover all the possible roles in an organization

It is false to say that Disciplined Agile (DA) roles cover all possible roles in an organization. DA defines a set of primary roles (such as Team Lead, Product Owner, and Architecture Owner) and supporting roles for agile delivery teams. However, it does not prescribe all roles that might exist in an organization, such as executive leadership or specialized departments outside the agile delivery context.
