I often think of a question, why these standards, at the first place, require us to demonstrate or achieve 'Continual improvement' (in the effectiveness of QMS or of the EMS or OH&S). The requirement of 'Continual Improvement', in my opinion, stems from the
overall intention with which each of the standard was developed.
ISO 14001 The overall aim of this International Standard is to support environmental protection and prevention of pollution in balance with socio-economic needs.
OHSAS 18001 The overall aim of this OHSAS standard is to support and promote good OHS practices, in balance with socio-economic needs.
While the aim of
ISO 9001 is to enable the organization to establish a system to consistently provide product that meets customer requirements and enhance customer satisfaction.
While the approach behind developing 14001 & 18001 is philanthropic, addressing wider socio-economic needs of people not confined within any specific boundaries, the aim of ISO 9001 is confined to and targeted at the organization's own business needs and the needs of its customers.
Now, what I am interested to know is whether the answer to my question (improving the Effectiveness v/s making the whole system effective) has any linkage with the overall aim these standards were developed with.
