Seven Tools of Operation Standardization for Mass Production of a New Product

We propose the effective tools of operation standardization for mass production of a new product. The cycle of operation standard consists of three stages of design, improvement and evaluation, and divided into seven steps, that is, decision, communication and understanding, observance, supervision, notice, decision again, and evaluation. The proposed seven tools of operation standardization (OS7) correspond to these steps. These tools enable us to realize mass production of a new product and to stabilize a product quality much earlier.
