A case study research was conducted at a local car seat polyurethane (p/u) injection manufacturing company by extensively exploiting the work study methods and techniques during the on-site studies. Two fundamental approached in work study namely method study and work measurement offer a systematic and organized steps in the research studies. The work measurement has been widely used as a method for measuring actual working time via its several techniques i.e time study. This paper discusses on the application of the work measurement technique in establishing a benchmark time for producing the car seat p/u injection line of the case study subject. Appropriate formats used for data organization are presented.
The market and technology trends in automotive industri es nowadays undergo relatively fast and sometimes drastic changes. New materials and new production engineering processe s and techniques will continuously be introduced. Such introductions require improvements in production systems and its pr ocesses. It is crucial that manufacturers respond to such changes by continually improving and increasing their technolog y levels and capabilities in order to keep up with market trends and remain competitive. Nevertheles s, before any improvements could be done one must measure and evaluate its present operation using the available and well established tech niques that could fulfill their primary objectives . There are many improvement methods available for manufacturing operations. Example of such methods are, Total Preventive Maintenance (TPM), Total Quality Management (TQM), Japanese approach of systematic housekeeping 5S, Continuous Improvement (Kaizen), benchmarking, Theory of Constraints (TOC), Business Process Re-engineering (BPR), and BPR including kaizen - called business process improvement (BPI) as well as Organization Development (OD). All these methods have a similar fundamental aim, which is to impr ove operations . In a sepa rate study, Brown discusses on the role of work study in TQM and delib erately explained its relationship in term of approach and method for assessing the effective use of human and other resources . Work study divides into two complementary areas; method study and work measurement. Method study is concerned with the reduction of the work content of a job or operation, while work measurement is mostly concerned with the investigation and redu ction of any ineffective time asso ciated with it . Work measurement is an important contributor to the planning and cont rol of an operation, and offers a useful basis on which to evaluate alternative ways of delivering work . Time study is one of the oldest techniques in work measurement and it is concerned with direct observation of work while it is being performed [6 – 9]. The work study method is gaining its popularity lately and this is clearly evidence in the research done by the researchers  until . This paper presents work measurement st udies to evaluate the actual working time at car seat p/u injection manufacturing line. Time study technique was adopted to collate data during the on-site study. Benchmark time is established and the process improvement activities can be initiated based on the research outcomes.

his paper presents the work measurement study, particularly time study for measuring the actual working time at the car seat p/u injection line. Through this approach, it is found that the time study technique is an effective solution in measuring the actual working time. The research outcome sh ows that the benchmark time was successfully obtained and established. These13.42 minutes cycle time for 100% production efficiency and 14.09 minutes cycle time for 95% production efficiency can be used by the case study subject as its initial standard time. Therefore to achieve this standard time, a well coordinated process improvement or kaizen activities must be enforced and essential measures must be taken. Eventually, a well adopted standard time would be established an d from there on other kaizen activities can be carried out continually. It is hoped that this paper will benefit other researchers and profession als from industries in exploring the cas e- based research work particularly in employing the work measurement method and techniques. The work measurement method and techniques is a very versatile research instrument that can be app lied in measuring tasks or processes either from service or manufacturing industries.
