What problems would have occurred if the measurement system had not been developed,?
Answers
measurements are used to guide decisions, then it follows logically that the more error there is in the measurements, the more error there will be in the decisions based on those measurements. The purpose of Measurement System Analysis is to qualify a measurement system for use by quantifying its accuracy, precision, and stability.An example from industry serves to illustrate the importance of measurement system quality:A manufacturer of building products was struggling to improve process yields, which had a significant impact on product cost. Experience indicated that there were several process and environmental characteristics that influenced the process yield. Data were collected on each of the variables believed to be significant, followed by regression and correlation analysis to quantify the relationships in statistical terms.

What would happen without a set of standard units of measurement?
That has already happened. The Foot (unit) - Wikipedia was once used all over Europe, but every jurisdiction had its own length. Here’s a Viennese table (from Wikipedia) showing conversion values. The Viennese foot was 31.6102 cm, compared to a US or Imperial foot of 30.48 cm. Other feet ranged from 26.4 cm (Naples) to 34.8 m (Venice).
Other units were similar. This, along with the bizarre arithmetic (multiples of 3 abound), was a reason for the introduction of the metric system.
