P1, or "Project 1," is a term often used to refer to the initial phase of a project or initiative. It typically involves planning, research, and the establishment of goals. This phase is crucial for setting the foundation for future work and ensuring that all team members are aligned on objectives. In various fields, such as software development or business management, P1 can also denote the first version of a product or service. This initial version is essential for gathering feedback and making improvements before launching a more refined version to the public.
