Answer:
Option B. Maintain barriers between departments
Step-by-step explanation:
The reason is that Deming's 14 principles talk about the transformation and achieving better results by eliminating the barriers involved in transforming. Deming said that all those elements that are barrier to improvement, cost reduction and quality must be eliminated and a system of transformation must be designed that promotes constant improvement, change adoption, elimination of quotas and numerical goals, elimination of barriers between department so that better results like quality improvement and cost reduction can be achieved.
Hence saying Daming said that the barrier between departments must be maintained is wrong as it is barrier to transformation.
