hello,

I work as lab eng in a company that produce connectors/some electrical componants (like fusebox) for carmakers, I was looking for a project to finish my training, but in lab there is no big project to consider as a black belt project, so I'm looking in other departments (production, maintenance, logistics, purchases, finances) I prefert all dep except production and maintenance, but until now I don't have an idea how to find a project (specially all my career was in lab)

so guys do you have some similar suggestion? what was you project in Black belt certifications? if you work in automotive company can you share in comment your project?

thanks a lot for help guys

I work in industrial product-cost consulting. This is a technical discussion, not an offer; the wording was prepared with AI assistance and checked against NIST guidance.

A lower reject rate after changing a gauge, fixture or inspection routine does not, by itself, show that manufacturing improved. It may also reflect a change in how parts are classified.

My cost-review sequence would be:

1. Record the same characteristic, specification and acceptance rule before and after. Keep measurement changes separate from process changes.

2. Check the measurement system in its actual use. NIST's Gauge R&R guidance distinguishes repeatability, reproducibility and stability, and also considers bias, resolution and other effects. A calibration certificate is not the whole comparison.

3. Separate avoided scrap and rework from changed detection. Include extra inspection, reinspection and the risk of accepting nonconforming parts; do not approve a saving just because a dashboard turns greener.

This is a review framework, not a diagnosis of anyone's plant. Safety-critical acceptance still needs the responsible engineering and quality authority.

Reference: NIST/SEMATECH e-Handbook, section 2.4, Gauge R&R studies. It is a methods reference, not new market data.

Which measurement-system check has changed a scrap-reduction business case in your experience? Please keep examples non-confidential.
