Maximum flexibility in office workstation areas is achieved through the use of universal workstation sizes and shapes, configured in varying open plan groups to suit teams and tasks. Office workstation layouts should be modular, with the extent number of variations possible to facilitate future rearrangement if necessary. Choose the workstation size according to the functions performed by the user rather than job classification or status. Generally a combination of paper and computer based tasks will require more space than computer based tasks only. Workstation systems, as with all office and business furniture, should consist of components that can be reconfigured and reused without requiring multiple trades to disconnect and reconnect systems. Workstations and desks made up of separable free-standing components are preferable to integrated and custom-built office furniture that restricts re-configuration.
