Lean Six Sigma in electronics and aerospace
Assembling many components that look interchangeable makes the assembly error a permanent risk. It is the home ground of poka-yoke: making the wrong assembly physically impossible costs less there than any inspection added downstream.
The traceability requirement, for its part, turns the slightest nonconformance into a documented investigation. It pushes teams to treat the cause of occurrence and the cause of non-detection separately, and makes failure mode analysis less of a formality than elsewhere — it is genuinely used to decide.

Yamazumi chart
The Yamazumi chart stacks the work content of each station into bars and compares it with the takt time, to see at a glance who is overloaded and who has spare capacity.
Lean tools · case: Electronics manufacturing services
Poka-yoke / mistake-proofing
A poka-yoke is a device that makes the error impossible, or that flags it the instant it occurs, before it becomes a defect.
Lean tools · case: Electronics assembly
DPMO / sigma level
DPMO expresses the number of defects per million opportunities to make one — a basis that puts a simple product and a complex product on the same scale, and that converts into a sigma level.
Statistics · case: Electronics
Standardized work
Standardised work is the best sequence known to date for carrying out a task, written by those who do it, and meant to be improved as soon as something better is found.

Quality metrics
Scrap rate, rework rate, first-pass yield, cost of poor quality: quality metrics put a figure on what defects cost, and above all on where they occur.
Measurement and indicators · case: Aerospace supply

The training corpus is not split by sector: the questions are about the tools, which are the same everywhere, and the certifications do not split their exams by sector either. To find your level, the shortest way is a fifteen-question quiz, no account needed:
