To solve part of current working places' problems, this study attempted to utilize unified systems language (USL) based on information science and linguistics. USL is an interdisciplinary method with technique for translating business languages (natural language) into modeling languages i.e. DFDs (Data Flow Diagrams), ERDs (Entity Relationship Diagrams) and Mini-specs (Miniature specifications), universal modeling language UML and object constraints language OCL(OMG 2003), etc., which are ready to be fed to the systems development, software design, and/or programming language generation process. The USL method is applied to a job in one of the service industries in Japan and proven to be valid and both employer and employee are well motivated to achieve a harmonious relationship. This study also finds that efficiency rates are strongly correlated to the degree of environmental factors in working places. In other words, the degree of working place efficiency can be measured and controlled by the USL factors. It is concluded that the USL application to designing working places should be promising to further enhance the integrated Workplace-management with ecological approach.
