Answer: c. Decentralization
Step-by-step explanation:
Decentralization, a process that involves the relaxation of authority at higher levels and the redistribution of said authority to lower levels to enable faster decision making and independence.
This policy would work here because should shop floor employees feel they have more say in the company as well as some power to implement some ideas, it might motivate them to come up with more ideas as opposed to constantly waiting for approvals from the Corporate headquarters.
Local quality managers who uncovered the source of the quality control issues could have made appropriate corrections sooner if they did not have to wait on Corporate approvals for so long.
Decentralization would therefore ensure that matters are dealt with speedily and that innovation is improved.
