Quantitative Estimation on Relationship between Work Types and the Teamwork Level of Work Teams in the Ladies Innerwear Sewing Maker Plants : Industrial Teamwork Dynamics (Part II)

Abstract

Industrial Teamwork Dynamics (ITD) has been researching from positivism point of view through Social Survey in Industries. On the secondary research, this paper applies and verifies ITD as new paradigm using Group Dynamics of Social Psychology for group behavior at bottom line workers into the Japanese ladies innerwear sewing maker. The work types as work team were divided into three categories, group type as flow-line (sewing by machine), individual and crew type (checking textile and cutting), individual only type (inspection). The teamwork level was defined and extracted by PCA. The team productivity was confirmed as work efficiency, achieved ratio of actual work time to standard work time in each work team. ITD certifies group type refined better teamwork level than others according to G-P analysis (best ratio groups : 151 persons, bottom ratio groups : 173 persons including three work types) by ordered work efficiency ratio on every work type.
