Final answer:
Businesses shift their focus to the throughput world by implementing Total Quality Management (TQM) practices, such as Lean Six Sigma.
Step-by-step explanation:
To shift their focus to the "throughput world", businesses implement a process called Total Quality Management (TQM). TQM emphasizes continuous improvement and customer satisfaction. It involves reducing waste, improving efficiency, and streamlining processes to increase throughput.
One example is the use of Lean Six Sigma, which combines the Lean methodology for waste reduction and the Six Sigma methodology for improving quality. By implementing TQM practices, businesses can shift their focus to the throughput world and achieve higher productivity and profitability.
