As an AI language model, I don’t have real-life experience, but here are the steps that a business can take to determine its competitive advantage:

1. Identify your target market: Determine the group of customers you want to serve and understand their specific needs and preferences.

2. Research your competition: Identify your competitors and study their products/services, pricing, marketing, and target customers.

3. Conduct SWOT analysis: Evaluate your strengths, weaknesses, opportunities, and threats (SWOT analysis) to identify areas where you can excel and those where you may have to improve.

4. Determine your unique selling proposition (USP): Identify what sets your business apart from your competitors.

5. Focus on customer service: Provide excellent customer service that exceeds your customers’ expectations.

6. Innovate: Continuously work on improving your products/services to stay ahead of the competition.

7. Emphasize quality: Produce high-quality products and services that deliver value and meet customers’ needs.

8. Build a strong brand: Create a strong brand identity that resonates with your target customers.

9. Effective Marketing: Use marketing techniques like social media, search engine optimization, online advertising, and email marketing.

By considering these steps, businesses can determine their competitive advantage that can help them to stand out in the market or industry.
