One of the key elements of Total Quality Management is the concept of
continuous improvement. So why shouldn''t that also apply to the design of
training aids? Well it has, and the result is the Model WD-7 quincunx.
After listening to the "voice of the customer" it was determined that the
quincunx could be made even more effective by incorporating certain new features
like:
Smaller and smoother gate locks
An improved funnel
An easel stand that locks open
The ability to simulate distributions
The elimination of separate pin blocks.
