Sometimes I visit a Japanese website called “monodukuri.com” and answer to a question which a questioner asks on the website. I recently answered to a question regarding the QFD file management. So I summarized my answer here before I forget about it.

Many new projects for Lean Six Sigma and DFSS certification (Green Belt and Black Belt) start in October and November every year because the beginning of the fiscal year starts in October, and employees set up a new goal for the fiscal year. Obtaining the Lean Six Sigma or DFSS certification is one of their goal.

As a part of MSA (Measurement System Analysis), we analyze repeatability and reproducibility of a measurement system in a Lean Six Sigma project. It’s called Gage R&R. The Gage R&R can be categorized into two types – Continuous Gage R&R and Attribute Gage R&R.

I had a chance to help the technical support group yesterday and attended a meeting for troubleshooting. The meeting discussed a game plan for investing the problems and finding the root causes of the problems to solve. We used the parameter-diagram in the meeting because the problems and the root-causes were complicatedly interconnected.

I was asked by a black belt yesterday, who was in charge of a continuous improvement project for a factory in Dominican Republic. According to him, there seemed to be a problem in the soldering process which caused the solder bridges. He wanted to preform DOE to identify a main factor of the defect, and he already created a plan for the DOE.

Conducting a meeting with some engineers to a Design FMEA is pretty hard because the engineers are always busy. Gathering several engineers and conducting a long hour meeting not only makes a pressure on the project schedule but put an additional burden on the engineers. Even worse, the Design FMEA meeting does not create a tangible design elements. But the manager and the engineer could be relieved from the burden if they understand a positive effect of Design FMEA.

The Kaizen is very popular in manufacturing, it is, however, still not so much in office. Unlike the manufacturing environment, seeing waste is pretty hard in the office environment because many wastes in the office are intangible. Although an education for Kaizen is necessary to see the wastes, the Kaizen training is uncommon in the office environment and many office employees cannot see their wastes effectively.
