Internationally consistent ISO standards are in use, or are being developed, for quality systems, environmental management, and occupational health and safety. These standards outline a model for the management of quality, environment or safety. In many respects the process of developing management systems for these matters contains a number of common elements, including obtaining commitment from senior management; instituting consultative mechanisms; developing a policy; identifying components of the management program; resourcing, implementing, and reviewing the program; and integrating the program into the organization's strategic plan. The necessity of developing separate management systems for different organizational aspects is wasteful and inefficient. Better management systems will be developed if they are integrated into a single management structure.
