Value adding is a key driver in today‘s hospitality and restaurant business. Besides satisfying customers and having happy employees, a hotel manager must add value to the bottom line of its operation. The owners expect a return on investment and a certain level of profitability and this can only be achieved if managers know how to monitor their operations and control costs. Managers must be experts and acrobats in taking financial decisions, very often with only limited information and resources, and still be able to forecast the consequences of their choices. Mastering figures will give managers the competitive advantage and will put them in a position to influence the bottom line of their operations.
