When companies are considering acquiring another company, they do extensive due diligence. They analyze balance sheets, income statements, debt history, customer lists, physical assets and equipment, the product and/or service offerings, etc. This is done to make sure that the buyer knows what they are buying.
However, there is another aspect of due diligence that is typically not done. I call it the non-financial audit. This is an analysis of the organization: its strengths and weaknesses, biggest needs, strength of management, culture, values, work environment and impact of a sale on customers and employees.
