Since customer satisfaction plays a key role in success of business, number and quality of call centres have increased significantly in the recent decade. Effective use of the area is one of the most important criteria in call centres, since the operation floor may accommodate numerous employees within the defined area. This is where ergonomics comes into play: it ensures the products are able to accommodate long sitting hours. Sound insulation is also important considering long phone conversations. If the total area is used in the most effective manner and the design allows the employee to personalise his or her own space, this will not only increase the motivation of the employee but his or her productivity.
