In today's business world where customers place orders in real-time and manufacturers/suppliers are expected to have systems in place to process, fill and ship the orders in real-time, the application of just-in-time manufacturing (JIT) supported by information technology for communication (ITC) is a way forward. This paper reports the results of a study that investigated the role of managers' use of the (ITC) in the relationship between strategic business units' application of the JIT and financial performance. Data for the study were collected from 103 general managers (GMs) in charge of one strategic business unit (SBU) each. The results indicated that the SBUs' financial performance was positively associated with the interaction between managers' use of the ITC and application of the JIT. Specifically, as the application of the JIT and managers' use of the ITC increased; the SBUs" performance improved. Implications of the results are discussed in the paper.
