Workstation Type Follows Task Requirements
The task or the type of work determine widely the preferred type of working posture and hence the design of a workstation at a machine and the equipment needed for (see Figure 1). Most preferable are workplaces that allow to change posture as often as possible. If it is not possible to switch between sitting and standing, a seated working posture is preferable.
Preferred working posture
No particular musculoskeletal or visual requirements:
multiple, complete tasks
High visual performance:
Lack of movement
Precision work or work at a microscope, monitoring activities
High musculoskeletal performance:
Lack of recovery
Heavy manual handling: frequent movements
Figure 1: Task requirements determine preferred work postures.
Besides task requirements, other factors should be considered when designing workplaces and workstations (see Figure 2).
