Why we write one control plan per part
A control plan written from your drawing means the dimensions we measure are the ones that matter to you.
Without a per-part control plan, inspection defaults to whatever is convenient to measure: overall length, outside diameter, the features a gauge reaches easily. Those are rarely the features that decide whether a part works.
A control plan written from the drawing names the critical characteristics, the method for each and the frequency. It is a short document and it changes what happens on the shop floor, because the operator knows which dimension stops the job and which one is informational.
It also makes the measurement record meaningful. Shipping data against a control plan tells the customer something; shipping a list of easily measured dimensions tells them almost nothing about the features they specified.
