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.

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.

for want of a battle the war was lostfor want of the war the kingdom was lost,
