Quality control is essential to continuous improvement. It involves regular checks and validations of processes to ensure they are functioning correctly. This can include: - Routine Calibration: Regular calibration of equipment to maintain accuracy. - Standard Operating Procedures (SOPs): Developing and adhering to SOPs to maintain consistency. - Proficiency Testing: Participating in external proficiency testing to benchmark performance against peers. - Feedback Mechanisms: Implementing feedback loops to learn from errors and near-misses.
