Final answer:
The investment of $21 million in TQM to improve vendor/JIT processes by a company is chiefly aimed at gaining greater organizational strength by enhancing operational efficiency and competitive market position.
Step-by-step explanation:
A company that has invested $21 million in a Total Quality Management (TQM) initiative to improve vendor/Just-In-Time (JIT) processes is primarily aiming to achieve greater organizational strength. The investment in TQM and enhanced JIT processes is an attempt to improve operational efficiencies, reduce waste, increase customer satisfaction, and ultimately lead to a stronger competitive position in the market. While greater stock price may be a result of these improvements, it's not the direct aim of investing in TQM. Therefore, the correct answer to the question is A. Greater organizational strength.
