Dorian Shainin was an American quality consultant and engineer notable for developing the "Red X" concept for industrial problem solving and product reliability. Shainin tools provide a simplified approach to Design of Experiments to logically identify root causes of variation. The key Shainin tools are Iso Plot, Multivari, Component Search and Variable Search, Group Comparison, and Precontrol (stoplight control). Shainin referred to root causes as "Red X" primary causes, "Pink X" secondary causes, and "Pink-Pink X" minor but still controllable causes.

• Most notable for his contributions in the fields of industrial problem
solving, product reliability, and quality engineering, particularly the
creation and development of the "Red X" concept

3. Definition
Shainin tool is consider to be the
simplified form of Design of
Experiment(DOE) Technique.
Shainin Tools are a series of steps to
logically identify the root cause of
variation.
Shainin refers to root cause factors as the
“Red X”, “Pink X”, and “Pink-Pink X”
causes

4. Root Cause
Red X – the primary cause of
variation
Pink X – the secondary causes
of variation
Pink-Pink X significant but
minor causes of variation (a
factor that still can be
controlled!)
