This paper investigates in detail the current status of the implementation levels of JIT key-factors and their sub-elements within the cement industry within Libya, and its implication for management within the said industry. A survey methodology has been applied in this detailed investigation using an intensive questionnaire and one-to-one interviews of the correspondent organizations. Based on the analysis of the survey findings, the results show that the implementation status of the JIT key-factors and their sub-elements are found to be in the modest levels across all the surveyed organisations, thereby indicating to opportunities for eliminating waste and improving the value chain. This paper has also pointed to crucial areas where the senior management body within this industry need to take immediate actions in order to achieve an effective and successful implementation of JIT systems. The paper also makes a contribution by providing an insight into what extent the JIT key-factors and their sub-elements are understood and implemented within the key Libyan manufacturing industry.
