In the 36 years since the first edition of Shannon Pratt’s Valuing a Business was published, we have seen a proliferation of data, tools, and techniques for business valuation. Some of these have been incredibly useful, leading to more reliable valuations and ushering in a new era of “evidence-based business valuation.” However, this proliferation has made it difficult for appraisers to keep up-to-date on the latest developments in the field. There are also concerns that the profession is trying to turn the “art” of valuation into the “science” of valuation and becoming overly mechanistic in the process.
