An important practice for testers is to be involved as early as a possible.

The specific practice "Testers review test basis documents" belongs to thePeer Reviewsprocess area. At TMMi Level 3, the Peer Reviews process area involves static testing activities where testers and other stakeholders review key work products, such as requirements and design documents, to identify defects early in the lifecycle. By involving testers early through these reviews, organisations can enhance testability and improve overall quality.
