Metrics are measurements that include quantitative and qualitative, objective and subjective, economic and non-economic categories. All measurements are subject to error, including Manufacturing System Measures. Low-error-free measurements are labeled as reliable. The more reliable a measurement is, the fewer errors it has. Key Performance Indicators (KPIs) tend to be a mixture of quantitative and qualitative, objective and subjective, and economic and non-economic categories. What are the observations?
