Final answer:
Deming believed that quality improvement slogans, banners, and posters may give a false impression of progress. He emphasized the need for systemic change and critical thinking for sustainable quality improvement rather than relying on superficial motivational methods like slogans.
Step-by-step explanation:
According to Deming, quality improvement slogans, banners, and posters may create a superficial sense of improvement. Deming's perspective is that while slogans and posters can be eye-catching and communicate a message quickly, they do not necessarily lead to true quality or productivity improvements. Instead, they might just give the illusion of progress without addressing the underlying systems and processes that must be changed to achieve long-term and substantive quality improvement.
Creating an environment that supports quality improvement involves more than just posting slogans. It requires a commitment to continuous learning, process improvement, and a culture that encourages problem-solving and critical thinking. Thus, Deming would likely argue that for long-term and effective quality improvement, organizations need to focus on systemic changes and worker empowerment rather than rely on superficial motivational techniques.
