		+	Not right first time = 10^6 X (Quantity of defective units / Total quantity of units supplied)
		+
		+	NRFT can be measured internally and externally in the production cycle:
		+
		+	* Internally – defective units identified within the production process.
		+	* Externally – defective units that are identified outside the production process, either from the supplier or at the customer’s site.
		+
		+	A defective unit is a unit that does not conform to specification and may be scrapped or reworked.
