The best-design systems will achieve its goal only if it is implemented properly. Managers and supervisors at all levels must be vigilant to assure that everyone complies with applicable control procedures.
Even more importantly, the required procedures must be ones that workers will be comfortable using at all times, and which they will not be tempted to ignored when the procedures become inconvenient or in times of pressure and stress. Meeting this criterion is one of the key considerations in the design of control systems. Managers should also plan ahead for alternatife arrangements that might need to be put in place in the event an emergency requires bypassing the regular procedures.
