How can you ensure improvement in a process or system if you are unable to measure its performance?

Measuring performance is crucial for ensuring improvement in a process or system. Without measurement, it is difficult to identify areas that need improvement or track progress. To ensure improvement without measurement, one can focus on gathering qualitative feedback, setting clear goals and objectives, and regularly reviewing processes for any visible signs of progress or issues. However, implementing a system for measuring performance is highly recommended for more accurate and effective improvement strategies.
