Changes in Key PersonnelThere are three primary functional areas of a construction business, and each must be adequatelymanaged and supervised in a successful contracting enterprise. The primary functional areas are:• Estimating and sales (getting the work)• Construction operations (doing the work)• Administration and accounting (managing the business)In every successful construction enterprise, a top-level manager is responsible for each of theseareas or, in many cases, one person is responsible for all of them or two people share theresponsibilities. Page 19 of Schleifer’s Manual of Construction Business Practices, 2018If a company is making a profit, it is primarily, if not solely, because of the efforts or theseindividuals. If one of them leaves, there is by definition no track record of profitability for thenew organization as it was configured. This is a simple reality in business and even more so inthe construction business that is so often a closely held small or medium-sized company.
