Why are cross-functional teams emphasized in CBM T6 quality management?

• A. Limit participation to QA only
• B. Focus solely on cost reduction
• C. Emphasize speed over process robustness
• D. Leverage diverse expertise, improve root cause identification, foster buy-in and sustainable improvements

Answer: (D)

Cross-functional teams bring together people from QA, engineering, manufacturing, maintenance, and other areas to tackle quality problems from multiple angles. In CBM T6 quality management, issues often involve several parts of the process, equipment interactions, and human factors, so no single function has all the context. When these diverse perspectives collaborate, they can map the end-to-end process, analyze data from different viewpoints, and identify root causes that a siloed team might miss. This leads to more accurate root-cause identification and more effective, sustainable solutions. Involving different stakeholders also builds buy-in, since those who helped design and approve the fixes are invested in their success and ongoing monitoring. The result is improvements that endure because they are practical across the whole system and supported by the people who must maintain them. Limiting participation to QA misses essential expertise and ownership; focusing only on cost reduction can undermine quality and long-term reliability; and prioritizing speed over process robustness jeopardizes the durability of improvements.
