| + | |||
| + | Change what operators do than on change the devices they use. A workstation for an assembly line worker might be redesigned to eliminate manual lifting. Or a robot might be designed to lift the component. | ||
| + | |||
| + | ### Equipment design | ||
| + | |||
| + | Change the physical equipment that people work with. Apple’s design of the iPhone hardware and software demonstrates how important a focus on equipment design can be to a product’s success. | ||
| + | |||
| + | ### Environmental design | ||
| + | Changes the physical environment where the tasks are carried out. This can include improved lighting, temperature control, and reduced noise. | ||
| + | |||
| + | Designs of task, equipment and environment are usually considered together as the picture below. Cognition consideration are where we derives theories, principles and guidelines. Commonly seen cognition considerations are: [[time_delay|Response Time & Delay]] | ||

| + | ### Training | ||
| + | Enhances the knowledge and skills of people. This includes teaching and practicing the physical or mental skills. Training is most applicable when there are many repetitions of a task or long involvement with the job. Periodic training is also important for those tasks that are rare, but where performance is critical, such as fire drills and emergency first aid. | ||

| + | ### Selection | ||
| + | |||
| + | Changes the makeup of the team or organization by picking people that are best suited to the job | ||
| + | |||
| + | ### Team and organization design | ||
| + | Changes how groups of people communicate and relate to each other, and provides a broad view that includes the organizational climate where the work is performed. | ||
