This study is prepared on the ground of consulting business in an objective of an improvement of productivity that was proceeded on industrious-purpose reel manufacturer, S corp. the purpose of this study is to achieve an improvement of productivity of the production line of industrious-purpose reel via 4M analysis and separate team activities. The method for study was proceeded with 4M analysis via video recording, one of the steps of separate team activities. Separate team activity is newly established concept, indicating what is modified and expanded partial process among previously existing 6-Sigma methodologies so that measures of various variables in the manufacturing production line are applied. The first procedure is a 4M analysis via video recording. firstly, consultant records videos for relevant process, conducting 4M analysis based on collected data to derive wasting factors in each process. Secondly, it is a procedure to derive and select proper measures, meaning that measures for removing wasting factors based on derived results are elicited, selecting a measure with high probability of application via negotiation between consultants and separate teams. The last procedure is an application of selected measures to real production line, reflecting an environment of production field to derive an effect of increasing practical productivity rather than a qualitative effect as a measure with trust and flexibility.
