"Understanding the TDMM has enabled me to identify parts of cabling design that are unique to Japan.  As an RCDD, I can now respond to overseas customers recognizing the differences between my clients’ expectations and Japanese norms, so I can bridge the gaps between them. Telling customers that I am an RCDD affirms that I understand the TDMM, and I update my knowledge regularly."
