Purpose: Study was carried out to analyze the key factor that contributes towards worker productivity by determining the correlation, relationship and interactional features between comfort level, environmental factors (noise, heat and lighting) and workstation dimension. The identification of discomfort level was carried out among the operators of three automotive companies in Malaysia. Design/methodology/approach: Study was carried out to assess discomfort level based on ergonomical factors and to determine the distribution of body discomfort in relation to the tasks performed. The study was carried out based on questionnaire responses from the participating factories and the collected data was analyzed through the SPSS software. Findings: Findings from the analyzed data shows that the left arm is the most commonly used body part for activities involving lifting, pulling, twisting, carrying and holding. Furthermore, heat discomfort in the working environment is the dominant factor associated with worker productivity due to body discomfort arising from sweat. Developments towards improving the comfort level, environmental factors (noise, heat and lighting) and workstation dimension of the operators must be made to avoid further discomfort. Research limitations/implications: Work environment factors studied in this research are heat/sweat, cold environment, brightness/light, high level of noise, chemical radiation, thermal conductivity and work tool vibration. In addition, activities performed by the operators while working were also linked as the cause of body aches. Originality/value: It can be concluced that working enviroment that caused heat /sweat is the most significant discomfort in the job satisfaction analysis. Furthermore, through correlation analysis, the relationship and interactional features between comfort level, environmental factors (noise, heat and lighting), workstation dimension and activities performed by the operators while working were determined.

Purpose: This paper explores the barriers faced by Malaysian manufacturing companies in successfully implementing the Supply Chain Management (SCM). The study has highlighted some pertinent factors performing the barriers that are most frequently reported by the studied companies. Sixteen companies, from service and manufacturing companies were studied over a period of two years to assess their SCM practices through survey and interview processes. Design/methodology/approach: This part discusses the research design and methodological issues upon which the research is based. The explanation includes two types of research methods, short survey and follow-up interviews that were identified as being suitable to achieve the aims of this study, which is to identify the current problem of SCM practices within the Malaysian SMEs. Research design is a framework or plan for research used as a guide in collecting and analysing data. Findings: The results showed that the barriers are depending on the types or group of companies business; such as either it is an SME or a big company. The barriers inhibiting the practice of SCM can be summarized in the following factors: partnership with suppliers, limited expertise, management commitment, understanding of SCM, supported technologies and customer satisfaction. The findings are also compared with the results of a similar study on SCM in other country. Practical implications: Some suggestions are also offered, which is believed to be a good strategy to the companies to manage the SCM that will lead to sustainable competitive advantage and hence improve their market share. Originality/value: There are interesting barriers between the companies in Malaysia and other country in the respect of SCM implementation. These findings can be used by both Malaysian and other companies to work together or review the SCM strategies that will lead to sustainable competitive advantage and hence improve their business performance.

Purpose: This paper discusses the use of acceptance sampling technique as a practical tool for quality assurance applications to decide whether the lot is to be accepted or rejected. Design/methodology/approach: In Malaysia, single attribute acceptance sampling plan is widely practiced for quality assurance purposes in manufacturing companies. Literature showed that majority of past studies on acceptance sampling had focused on the development and establishment of new methods for acceptance-sampling application. However, there is none that had investigated the relationship between acceptance sampling plan selection and effectiveness of the selection. Therefore, in this study, the authors had analyzed the effectiveness the acceptance sampling plan application method and its implementation problems in manufacturing electrical and electronics products. The study was conducted by using case study methodology at three manufacturing companies coded names: company A, B and C. In this paper, the authors would like to share the case study companies' experienced of acceptance sampling plan selection and difficulties that they had faced during the course of implementing acceptance sampling in their production lines. Findings: The result from the three case study companies showed by implementing acceptance sampling they could easily investigate and diagnose their suppliers' product quality immediately upon their arrival at the company premise. Practical implications: The continuous improvement and review of acceptance sampling plan is important to improve the products quality and ensure continuous customer satisfaction. Originality/value: All the three case study companies agreed that acceptance sampling implementation had improved their product's quality in the market place.
