The document discusses understanding the total cost of ownership (TCO) when evaluating and implementing a customer relationship management (CRM) system. It notes that TCO includes direct and indirect costs over the system's lifetime, not just upfront costs. When comparing options like building a system internally versus purchasing one, managers should calculate TCO by estimating development, maintenance, and opportunity costs, as purchased systems can have lower long-term costs. The document also stresses evaluating both costs and benefits through a return on investment analysis to properly assess different CRM solutions.
