Abstract

This study aims to investigate the effect of Total Just in Time (JIT) (JIT purchasing, JIT operation, JIT Selling) on Lean operations in the Jordanian Pharmaceutical Manufacturing Companies (JPMC) to eliminate the following types of waste (overproduction, inventory, motion, transportation, over-processing, defects, waiting time, and underutilization).To achieve this object a questionnaire is developed, and distributed among the managers working at 14 Pharmaceutical Manufacturing companies (JPMC)that are registered in the Jordanian Association of Pharmaceutical Manufacturers. in addition to one company in the free zone, which negates the need for sampling. Data is collected from 107resived complete answered questionnaire, after data analysis, the normality, validity, and reliability of the tool are confirmed, descriptive analysis carried out, and the correlation between variables checked. Finally, the hypothesis impact tested by multiple regressions. The results show that there is a high implementation of Total Just in Time practices in Jordanian Pharmaceutical Manufacturing Companies (JPMC). The JIT Selling has the highest rate of implementation, then JIT Operation, finally JIT Purchasing. Furthermore, the findings depict the high implementation of Lean Operations’ sub-variables, The Inventory waste had the highest mean, then Over Production waste, then Over-processing waste, then Transportation waste, then Defect waste, then Waiting waste, then Motion waste, and finally Underutilization Waste. Moreover, the results indicated that Total JIT practices affected Lean Operations significantly, and indicated that the relationships between total JIT sub-variables (JIT Purchasing, JIT Operation, JIT Selling) and Lean Operations are strong in Jordanian Pharmaceutical Manufacturing Companies. The study recommends the (JPMC) to pay more attention to Total JIT implantation in the industry for their important role in waste reduction. Keywords: Just in Time, Lean Operations, JIT Purchasing, JIT Operation, JIT Selling, Jordanian Pharmaceutical Manufacturing Companies.
