Especial atttention attention to safety issues is needed in the design and developmen of such systems; in particular, the adoption of a safety culture is advised. | ||

A safety culture is where all involved in the enterprise constantly think about safety, act safely and suggest actions to improve safety. [[Leadership|Democratic leadership]] is essential in a safety culture. A suggestion to improve safety made by any employee must be considered and, if appropriate, action is taken.
