A manufacturing company is required to have suitable methods in place for monitoring and measuring the processes involved in their quality management system. According to ISO 9001, “These methods shall demonstrate the ability of the processes to achieve planned results.” Essentially, what this requirement is asking you to do is to confirm that you’re having a good production day and your product is achieving the required specifications. To do this, you need to compare the actual results of your process to the intended results.
The definition of monitor is to observe and check the progress or quality of something over a period of time; to keep under systematic review. Measurement is defined as the act or process of measuring something; a size, length or amount known by measuring the item. Monitoring can be beneficial in catching a process that’s going out of range before it becomes an issue. Measuring is used in real-time to capture the actual values of the item in question.
Examples of areas that would benefit from process performance measurements could include:
- Process capability
- Reaction time
- Measurable aspects of dependability
- Effectiveness and efficiency of employees
- Waste reduction
- Cost allocation
