What is the specific differences and relation between Business management system and quality management system?

Business Management system is a general term. it contains the Quality management system and the Risk Manageemnt system ....etc and all others

Now, the main reason for any business (lets say at least for commercial business) is to make profit. Profit is related to customer satisfaction, employee involevment, social responsibility ...etc.

So the main difference is the SCOPE.

The Quality Management system is related to customer and product quality.

for example: if your objective is to increase the profit by lets say10%,

then the prodution wise will try to increase its production

but the Quality focus on customer retention, improve quality, reduce waste.

but wait, what about employee health and saftey? you might not find a single objective relating to emloyee health?

this is why you'll have an objective to reduce number of accidents and hence reduce treatment and insurance bill which will increase the profit by reducing cost

the goal is one but the scope of work is diiferent.

BMS focus on how to ahieve business goals. Where as QMS can be usefull in achieving the goals of business.

I am not familiar with "Business Management System" but I can guess it is the management system that has no reference to any quality management formal standard ! simply, it is how any business is run and achieving success in market and among customers in terms of financial success, image, etc. On the other hand, the quality management system is built to satisfy the requirements of a management standard but unfortunately, in many cases it is built to satisfy mainly the Certification Body ! for example, many companies copy and paste the ISO9001 standard - almost - and call it "Quality Manual" without real deep customization to the business ! finally they have two systems, one to present for the certification purposes and the other they use to actually run the business !

I believe the best situation is: to have a developped business management system that satisfies the requirements of applicable quality standards, in other words the quality standard serves the businesss not the business satisfying the standard for certification.

Business management such a general or common system where includes quality, quantity,risk and other issues.

It seems that everyone knows the difference between a system and a process. We know processes and systems are related, but most of us aren’t sure when one begins and the other ends. ISO 9000 provides definitions, but they seem inadequate at times.

Understanding the differences between a process and a system is important for effective organization management and auditing programs. Understanding some of the dynamics will help in the development of value-added auditing strategies.
