Procedures vs processes

Answer:

The process approach is required by ISO 14001 and it is demonstrated by applying requirements of the standard to appropriate processes. For example, clause 8.1 Operational controls, contains specific requirements for design and development and purchasing among other, more general, requirements for operational control. But, it doesn't mean that you need to create a process model or to document process procedures. If you implement only ISO 14001, you will need to document only operational controls for the processes and that only to the level you determine as necessary.
