The reasons that lead a company to become certified can be of both internal and external ones.
The main benefits are:

• effectively and continually improve performance and internal processes and their control
• increase the capacity to satisfy customer requirements and expectations​
• decreasing costs related to inefficiency of activities carried out
• precisely define all responsibilities and the professional development programme for resources used
• managing and improving aspects related to environmental, worker health and safety, energy related, social responsibility, etc.
• clearly communicate the results to reference markets

Besides, an impartial third-party body verifies and certifies to the market that the organisation is working to systematically improve its performance, with increasingly ambitious objectives related to continuous improvement.
