Just-in-time processing is a business philosophy that focuses on reducing time & cost & eliminating poor quality. this is accomplished in manufacturing & non-manufacturing processes by: a) moving a product from process to process as each function is completed. b) combining processing functions into work centers & cross-training workers to perform more than one function. c) having production supervisors attempt to enter enough materials into manufacturing to keep all manufacturing departments operating. d) having workers typically perform one function on a continuous basis.

B) combining processing functions into work centers & cross-training workers to perform more than one function.

Explanation:

Under just in time, the main focus of production is shifted from inventory management to quality management, as no more inventory is held in stock in abundance and cost of storage is cut down, for this various work processes are combined, so that the work is performed in a sequence without any delay.

In this manner, there is critical training towards the waste management, and quality management, and time management.

Just in time approach is mainly about maximum achievement with least cost, which involves grouping of processes, and work centers so that the time and cost both are used least.

Thus, statement B) is correct.
