Some common customer requests are listed below.

          • Teach modeling technique for a defined set of assembly problems
            –Eg. Electrical Motor Requirements: axial end play, case-cover fit, rotor–stator clearance, etc.
          • Teach analysis interpretation and optimization to personnel responsible for downstream functions like product quality, manufacturing and assembly, supplier quality certification, and inspection
          • “Teach CETOL 6σ analysis reuse, i.e. mapping, for similar products”
            – Eg. Customer makes seven different sizes of electrical motors but geometrically and technically the design is the same. One CETOL 6σ  “template” can be created to analyze all seven motors

          As part of the process, a CETOL 6σ Modeling is developed for specific assembly analyses.
