To improve team performance, which training should be provided?

Providing a workshop on test design techniques is essential for improving team performance in a testing context. This type of training enhances the team's ability to create effective and efficient test cases, ensuring that they can identify defects more accurately and thoroughly. Test design techniques, such as boundary value analysis, equivalence partitioning, and decision table testing, equip testers with the skills to derive meaningful tests from requirements.

By focusing on these methodologies, the team can improve their testing strategies, optimize their testing efforts, and ultimately deliver higher-quality software products. When testers are well-versed in various design techniques, it enhances collaboration, as they understand how to communicate and justify test cases based on structured approaches.

In contrast, while training in specific domains or on reviewing requirements may be useful, they do not directly address the core skills needed for effective test design and may not provide immediate benefits in terms of testing efficiency or effectiveness.
