Question

What are the three primary technical tools used for quality control and improvement?

Answer 1

The three primary technical tools for quality control and improvement are the following:

1.  Statistical process control: It is an standardized industrial methodology for the measurement and control of quality during the process of manufacturing. With the real time statistical process control reduction of variability and scrap can be done easily.

2. Design of experiments: It is basically used to find cause-and-effect relationships. It is a method used to determine the relationship between factors affecting a process and it's output. This helps in the management process of inputs in order to maximize the output.

3. Acceptance sampling: It uses statistical sampling to determine whether to accept or reject a production lot of material.

Answer 2

The three primary technical tools used for quality control and improvement are given below.

• Statistical Process Control

• Design Of Experiments

• Acceptance Sampling

These tools are used to ensure that quality is maintained and that the improvement is done in every subsequent lot based on the observations in the last lot.
