1. Select the companies and transactions based on criteria such as industry, financial metrics, and geography

2. Determine the appropriate metrics and multiples for each set -- for example, revenue, revenue growth, EBITDA, EBITDA Margins, and revenue and EBITDA multiples -- and you calculate them for all companies and transactions

3. Calculate the minimum, 25th percentile, median, 75th percentile, and maximum for each valuation multiple in the set

4. Finally, apply those numbers to the financial metrics for the company you're analyzing to estimate the potential range for its valuation
