In a hybrid project life cycle, which combines elements of both traditional (predictive) and agile (adaptive) methodologies, empowering the team to self-organize and make their own decisions is often the most effective approach. This is particularly true in situations where requirements are continuously changing, as it allows the team to adapt more quickly and effectively. In this scenario, the project manager should empower the team to advance the stones without waiting for his or her approval, thereby increasing the speed and efficiency of the testing process.
