Detailed Explanation:

The correct answer is A. Lack of constancy of purpose.

W. Edwards Deming identified several organizational problems that undermine quality management effectiveness. These are often referred to as the " Seven Deadly Diseases " of management. One of the most significant among them is lack of constancy of purpose, meaning organizations fail to maintain a consistent long-term commitment to improving products and services.

Lack of constancy of purpose occurs when organizations:

Focus on short-term financial results rather than long-term improvement

Frequently change priorities or direction

Fail to sustain improvement initiatives

Do not consistently invest in quality and innovation

This instability prevents organizations from developing strong quality systems and continuous improvement culture.

Why the other options are incorrect:

B. Emphasis on long-term profits

Deming criticized the emphasis on short-term profits, not long-term profits. Long-term thinking is actually encouraged.

C. Mandating zero defects

While some quality programs emphasize zero defects, it is not one of Deming ' s seven deadly diseases.

D. Eliminating work standards

Deming criticized rigid numerical quotas and poorly designed performance targets, but eliminating work standards is not part of the seven deadly diseases.

Quality Management Excellence frameworks emphasize consistent long-term improvement strategies, which directly addresses Deming’s concern about lack of constancy of purpose.
