EXACTNESS
The first step in the improvement journey is Exactness. This involves three parameters:Exactness of Process: The vendor must ensure that the process is being followed exactly as per the standards, as per written down instructions. To achieve this the vendor must employ check points in Daily Work management.
Copyright ©. All rights reserved. 10 Training Support Consultancy
EXACTNESS
Exactness of Measurement: Any process is as good as its measurement. The vendor must ensure that there is a control plan for all the instruments & measuring gauges; periodic calibrations are carried out as per the plan & all instruments /gauges are kept in good working condition.

Small Things Count [ Benjamin Franklin ]For want of a nail a shoe was lost,
for want of a shoe a horse was lost,for want of a horse a rider was lost,
for want of a rider an army was lost,for want of an army a battle was lost,
for want of a battle the war was lostfor want of the war the kingdom was lost,
And all for the want of a little horseshoe nail.“We are as Strong as our weakest link”
A defective part that costs a few Dollars can make a final assembly nonconforming or, even worse , result in a field failure.
