The paradoxes of just-in-time system: an abductive analysis of a public food manufacturing and exporting company in Thailand

Purpose - study aims to investigate the implementation and impact of a just-in-time (JIT) system in a food manufacturing and exporting company in Thailand. Design/methodology/approach - At the company, the authors used an anomaly case study. The authors performed content analysis on the data collected through semi-structured interviews and direct observations to determine operational flows through customer order, production and delivery. The authors constructed a framework that helped in mapping current operations and subsequently assessing JIT’s impacts; the authors reported the best practices to the company’s owner. Based on the follow-up after a year, the authors used an abductive approach to refine the JIT theory using data from case organizations and relevant studies. Findings - The company encountered errors and delays in international delivery owing to inadequate inputs resulting from uncertain agricultural production, delayed contact with freight forwarders, improper documentation and insufficient staffing. Besides the highly centralized system, the limitations of the JIT philosophy contributed to the issues, thereby increasing mental and physical health problems and turnover rate. Owing to these paradoxical effects, the authors extended the JIT theory. Of the study’s several recommendations, the company observed only the following: contacting the freight forwarder after the purchase order confirmation, not production completion. The authors observed increased customer satisfaction, despite the additional cost of booking containers early. Originality/value - This research presents a balanced JIT that can minimize JIT’s impacts and resource shortage, owing to demand-supply uncertainties and sustain competitiveness.
