Mia (2000) adds that this is because managers working in JIT manufacturing environments have
little or no slack resources available to cushion against the difficulties caused by defective raw materials, production errors, irregular supply and demand schedules or to mask inefficiencies which makes the performance-related information provided by management accounting systems critical in such an environment. Mia’s data from personal interviews with the financial controllers of 55 organisations located in Australia (of which 28 had adopted JIT and the rest had not) suggest that those organisations that have adopted JIT, and that have a high (low) provision of information, earn high (low) profits.
