The Shainin technique is a problem-solving methodology used for quality improvement. It involves defining the problem, quantifying it, generating clues, performing experiments in repeated trials to evaluate the problem when "on" and "off", and establishing new tolerances to fix improvements. Variability is applied within a unit, across similar units, and over time by comparing best and worst samples to find differences in medians and experiment ranges and identify the exact cause.

1. SHAININ TECHNIQUE
• It is a problem-solving technique which is used for quality-improvement.
• It is also known as “Statistical engineering” or “RED-X” methodology.
• It basically diagnoses the problem and provides a remedy in a structured
manner.
• Firstly, we try to identify the problem, which we term as “GREEN Y”.
• Then, we analyze which types of variability can be attached to it.

2. PROCESS FLOW TO APPLY SHAININ
TECHNIQUE
• Define the problem.
• Quantify the problem.
• Try to generate clues about the problem.
• Perform some experiments(in a repeated manner).
• We try to evaluate the problem in “OFF” and “ON” state.
• We establish new tolerances.
• Fix the improvements.

3. WHEN AND HOW TO APPLY
VARIABILITY?
• First, try to apply within the unit.
• Then, try to apply in many similar units.
• Then, try to apply from time to time.

4. • In unit to unit, try to find Best of Best(BOB) sample and Worst of
Worst(WOW) and try to compare them.
• Then, find the difference of medians to the difference of ranges of
experiments. It will help to find the exact cause.
