To demonstrate top management's leadership and commitment with respect to the quality management system, the following four actions would be indicative: B: Briefing staff on the development of an improvement culture: This shows that top management is actively involved in promoting a culture of continuous improvement, which is a key aspect of the quality management system1. C: Chairing management review meetings: By leading these meetings, top management demonstrates their involvement in the quality management system's ongoing performance and commitment to its continual improvement1. E: Investing time and money in corrective actions arising from nonconformities: This indicates that top management is committed to addressing issues and ensuring that the quality management system is effective and continually improving1. G: Promoting the importance of following procedures: When top management emphasizes the importance of adherence to procedures, it reinforces the significance of the quality management system and its processes1. These actions align with the requirements of ISO 9001:2015, which emphasizes the need for top management to take accountability for the effectiveness of the quality management system and to promote a focus on continual improvement and customer satisfaction123. Approving company car budgets, conducting disciplinary meetings, and not attending the audit closing meeting do not directly demonstrate leadership and commitment to the quality management system1.
