A Quality Management System (QMS) in pharmaceutical and life science firms is a structured framework of processes, procedures, policies, and resources designed to manage and improve the quality of products and services throughout the entire organization. The implementation of a QMS is crucial in these industries to ensure compliance with regulatory requirements, maintain product safety and efficacy, and continuously improve operational processes. Here's an overview of the key components and principles of a Quality Management System in pharmaceutical and life science firms:

### Key Components of a Quality Management System:
