[Reference:Clause 0.1 (General) of ISO 9001:2015 specifies that a QMS enables organizations to achieve better performance by consistently meeting customer needs and improving their processes. It further highlights that continual improvement is a cornerstone of the standard (Clause 10.3)., Option Analysis:, A. Manages the performance:Incorrect. A QMS provides a framework to manage processes, not directly manage performance. The improvement of performance is an outcome of managing processes effectively., B. Monitors the performance:Incorrect. Monitoring is a component of performance evaluation (Clause 9.1) but does not define the overall purpose of the QMS., C. Dictates the performance:Incorrect. ISO 9001 does not "dictate" performance but allows organizations to set their own objectives and improve their operations based on their specific context and goals., D. Improves the performance:Correct. The fundamental purpose of a QMS as per ISO 9001 is continual improvement of the organization’s performance. This includes improving operational efficiency, customer satisfaction, and product/service quality., Why Option D is Correct:ISO 9001:2015 emphasizes the Plan-Do-Check-Act (PDCA) cycle and risk-based thinking, which are designed to drive improvements in organizational performance. Continuous assessment of processes and customer feedback ensures that the organization can adapt, innovate, and improve its effectiveness over time., Relevant Clauses Supporting the Answer:, Clause 0.1: Purpose of the QMS., Clause 10.3: Continual improvement ensures that the QMS remains effective and aligned with organizational objectives., Clause 4.1: Context of the organization, which requires the QMS to align with organizational strategies and improve outcomes., , , ]
