Dear Gireesh / Simon,
Auditing is not my field but a little googling suggests that the word 'accreditation' may have a flexible usage which is not confined to its application by ISO (Simon's link unfortunately requires a money input to progress very far (dear, fat, old ISO)).
Eg - ' Accreditation is a process in which certification of competency or authority is presented. It can be used in a wide variety of fields:'

Perhaps this could fit the 17025 question ?
Or
Integrated Pest Management
What is the IPM Accreditation Program?
The IPM Accreditation Program (IPMAP) recognizes companies, park systems, golf clubs and their superintendents, and other interested institutions who demonstrate their knowledge of and commitment to the principles of IPM through a process of certification, audit, and professional development.

I suspect this is another of those deceptively simple questions and await further responses with interest even if they demolish the above.
Regarding
HACCP, I have seen this described in many ways - eg concept, methodology, [management] system etc (although never from memory as standard). It may be another question of 'whose definition' you prefer. I pass for the moment.
