Lean Manufacturing, OEE and TPM

The shop-floor half of manufacturing excellence, built in the order a line is actually improved: value and the eight wastes, gemba walks and bottlenecks, lead time and takt time, value stream mapping, flow and cells, pull and kanban sizing, standard work and 5S. Then the two numbers a plant manager is judged on. OEE calculated from a real shift, the six big losses behind it, quick changeover, and total productive maintenance through its eight pillars and twelve implementation steps.

  • Calculate availability, performance, quality and OEE from one shift of real line data
  • Split a shift of downtime across the six big losses and name the one costing most
  • Draw a current-state value stream map with observed data boxes, then a future state you can reach

Automotive Core Tools: FMEA (AIAG-VDA 1st Edition)

The core tool an automotive customer audits hardest, taught to the 2019 AIAG-VDA handbook: the seven-step method, the five T's, the three-level structure tree, functions written so the failures fall out of them, effect against mode against cause, prevention against detection controls, the severity, occurrence and detection tables, the Action Priority table that replaced RPN, optimisation with owners and dates, results documentation, a reverse check on the shop floor and the supplemental FMEA-MSR.

  • Scope a PFMEA with the five T's and set a boundary you can defend to a customer
  • Build the three-level structure tree and write every function as verb, noun and requirement
  • Place failure effect, mode and cause at the right level so the argument about which is which stops

Practise what you learn in the free 3D lab

Technical work is judged on what you can do: wiring, commissioning, finding a fault. Doing a task yourself teaches more than watching it a second time, and a lab lets you try it safely before you meet real equipment. It does not replace working on real hardware.

How to choose

Six Sigma Green Belt Training teaches DMAIC and the statistics behind it. Automotive FMEA follows the AIAG-VDA method suppliers are asked for. Lean Manufacturing, OEE and TPM covers the shop-floor side.

Machine Vision Quality Inspection and the Power BI OEE dashboards course add the data tools that make quality measurable in real time.

The automotive core tools are taught as a set: SPC and MSA covers control charts, capability and gauge R&R; APQP, Control Plan and PPAP covers how a new part is launched and approved; and IATF 16949 Automotive QMS and Internal Auditing shows how auditors test all of them.

Lean Six Sigma Black Belt follows Green Belt with hypothesis testing, regression and designed experiments. ISO 14001 Environmental Management covers the environmental management system and its internal audit.

Questions

Is this an official Green Belt certification?
No. It teaches the Green Belt body of knowledge; accredited belts are issued by certification bodies.
Which FMEA method is taught?
The AIAG-VDA FMEA handbook method.
Is there a free course on the automotive core tools?
Yes. SPC and MSA, APQP and PPAP, and Automotive FMEA together cover the core tools suppliers are asked for, and the IATF 16949 course shows how they are audited.
Is the Black Belt course an official certification?
No. It covers the Black Belt body of knowledge and prepares you for exams such as ASQ CSSBB; the EDWartens certificate is a certificate of completion.
Is it only for manufacturing?
The examples come from manufacturing, but the methods carry over to other sectors.
Is it free, and is there a certificate?
Every lesson, note and assessment is free. The EDWartens certificate is optional and paid, and you can finish without it.
