The expert knowledge required to implement ISO9001 could be attained by internal staff. However, the cost to achieve the same competence level as an external consultant is considered prohibitive by most organizations, given that the implementation project is always going to be short-term. Organizations therefore make the decision to use external consultants.
There are other additional benefits from the use of an external ISO9001 Consultant that organizations do not always consider at the outset. These include the knowledge of what would be acceptable to certification bodies, and the instant benchmarking that the consultant brings to the organization, where the organization learns Best Practice from others that the consultant has seen. There are also potential networking opportunities and contacts that the consultant may have, that could prove invaluable.
Many organizations also retain the services of the ISO9001 Consultant post certification, due to their knowledge of the organization and the implemented systems, to assist with maintaining the quality management systems on an ongoing basis. This utilises the knowledge the consultant has built-up through the course of the project, reduces spend on internal resource, and ensures ongoing recertification.
