"The goal of any due diligence investigation is to avoid a bad business or investment decision." This quote is from Trace Investigations founder and expert Don C. Johnson, Certified Legal Investigator™, in the reference text, Corporate Investigations, published by Lawyers & Judges Publishing Company, Inc., 2002 edition. Johnson authored Chapter 11, "The Due Diligence Investigation," which still serves as a manual for conducting an investigative due diligence.
