Phase 3 typically refers to the final stage in a multi-phase process, often seen in clinical trials or project development. In clinical trials, this phase tests the effectiveness and safety of a treatment on a larger group of participants, usually involving hundreds to thousands of people. The goal is to gather comprehensive data to support regulatory approval. In project management, Phase 3 often involves the implementation of the project plan, where the developed solutions are put into action. This phase focuses on monitoring progress, making adjustments as needed, and ensuring that the project meets its objectives before concluding.
