Application of Mizenboushi (GD
) Method of Problem Prevention to Vehicle, Component and Subsystem Validation
The GD₃ or GD Cubed method of problem prevention has been
applied to product changes and to test results at the component,
subsystem and vehicle level. GD₃ stands for Good Design - Good
Discussion - Good Dissection.
Good Discussion of changes (Design Review Based on Failure Mode)
identifies BUDS of PROBLEMS that may arise from interfaces and
areas of change. Good Dissection (Design Review Based on Test
Results) is applied to physical test samples during and after tests
to identify Buds of Problems that may not be obvious from
inspection of the parts or test results.
The paper first describes implementation of the GD₃ principles
and methods supporting Good Discussion (DRBFM) and Good Dissection,
and then discusses how they are applied and embedded in the Vehicle
Development Process at General Motors Co.
