My background is in network engineering, workstation and server design and building, and Electrical Engineering. I was working on a Bachelors in Electrical Engineering and another in Mathematics. So I took every math course offered for both. I had the statistics course offered after trigonometry. I took Statics and Dynamics which lightly touch statistical analysis. I took Statistics for Engineering design that went into MTBF and other concepts for testing your design for failure analysis. The standard Six Sigma program goes into statistics for processes.
We learned as part of my B.EE, project design. It covered project plan of what we would design. Why we were designing it. Cost analysis was part of the project. Failure analysis of the components. Our designs took component placement in the design into consideration. Which components would have the lowest MTBF. Basically, which one should fail first and how easy can it be replaced. We designed to increase the time to failure. We would work out the differential equations for voltage, current, etc. We would simulate the designs in the lab. We would use MATLAB and other tools. We were not fixing current designs and troubleshooting them like in the methods below.
One day I am going to map PBM, PPDIOO, PDCA, DMAIC, and ITIL to see how they logically follow each other.
