Let’s say you ship a QC inspector to one in every of your provider’s factories. His goal is obvious: report on the standing of manufacturing, on the conformity and security of the merchandise made for you, and on the variety of defects he finds.
Nonetheless, it falls wanting its potential in serving to you attain your targets.
If there may be steady or near-continuous manufacturing of your orders within the manufacturing facility, there may be definitely extra you wish to know.
You’ve recognized course of controls as being troublesome…
Just a few days in the past, I spoke to an importer who retains having points with inconsistent paint high quality on their metallic merchandise. It’s clearly an issue of course of controls. In a minute I gave them an inventory of subjects that may be checked:
- Earlier than preparation baths: are the components saved freed from mud and grease? Do individuals contact them with out gloves? Are they in entrance of a fan?
- Preparation baths: does it appear they’re recurrently cleaned (content material changed)? Do they maintain checking the content material of the baths?
- Paint materials: does the manufacturing facility have a strategy to test that they’re constantly getting the identical high quality of paint? For instance, do they measure viscosity and shear on some/the entire batches they obtain?
- Throughout powder coating: test if the temperature of the air going to the spray weapons is under zero levels C.
- Throughout powder coating: are the components hung properly, with out the painted floor getting in touch with anything? Is there a excessive probability of contaminants floating within the air?
- Throughout powder coating: does it appear the spraying is laid evenly on all sides & areas of the components?
- Have they got a temperature gauge on the oven, does it appear to work?
- After that entire course of: are the components thrown (or broken in any method) when they’re transported or processed, at any level?
This isn’t an exhaustive checklist, after all. However the excellent news is, placing stress on a manufacturing facility in order that they pay extra consideration to these factors can go a good distance towards stopping high quality points on the completed merchandise.
Redeploying high quality inspectors to course of enchancment actions
So, in an effort to maneuver assets steadily from product inspection to course of enchancment, the inspector can spend 1 hour every week taking a look at these subjects. That’s not loads if he spends 2+ days every week in that facility. Nevertheless it can have an amazing influence.
Over time, if that helps, improve the time spent on course of audits, and cut back a number of the end-of-line inspection exercise. That exercise continues to be vital, because it signifies what processes might not be below management.
In How High quality Planning Drives QC and Course of Enchancment, I drew the general logic of fine high quality administration this fashion:
Here’s a common clarification:
The general logic goes like this:
-
Be certain your targets are clear and use that to qualify suppliers.
-
As suppliers get audited, you uncover dangers, which you’ll tackle.
-
Plan for essentially the most applicable strategy to examine and check parts, processes, and completed merchandise.
-
The findings level to additional gaps, permitting you to refine the general plan.
-
Deal with these gaps with remoted corrective motion requests.
-
When potential, undertake a extra system-wide strategy, for instance with a management plan.
-
At common intervals, assessment your targets and replace your plan.
One other strategy is to ship engineers to the manufacturing facility on occasion, to do full-blown high quality and/or course of audits. That may work effectively, too. However you may nonetheless need your lower-skilled workers to do a number of the comply with up over time.

How about you? Do you comply with a versatile strategy to high quality administration by utilizing inspectors to audit processes as described with the intention of getting forward of points that might have an effect on high quality later?
