During the "plan" phase of the Plan-Do-Study-Act (PDSA) process, the primary task is A. Determine how to collect data. This phase involves setting objectives, defining the scope of the project, and developing a detailed plan of action, which includes determining the data collection methodology that will be used to assess the project's effectiveness. It's important to have clear timelines and obtain buy-in from all stakeholders to ensure a smooth planning process. The planning phase is critical for laying the foundation for a successful project and includes making hypotheses about the outcomes.
