Final answer:
All options indicate that a business has gained competitive advantage except for a balanced budget.
Step-by-step explanation:
All of the options provided in the question can indicate that a business has gained competitive advantage except for a balanced budget.
A. Customer-supplier intimacy refers to a strong relationship between a business and its suppliers/customers, which can give the business a competitive edge.
B. Improved decision making can lead to better strategies and competitive advantages.
C. Operational excellence focuses on efficient processes, which can enhance a business's competitiveness.
D. New products, services, and business models are often key factors in gaining a competitive advantage.
However, maintaining a balanced budget alone doesn't necessarily indicate a competitive advantage, as it doesn't directly contribute to improving customer satisfaction, innovation, or operational effectiveness.
