Co Serve is committed to ethical business practice and corporate social responsibility.

' If you are in business you are formally entitled to pursue self-interest whereas in the professions you consciously choose to subordinate your own interests to those duties owed to others '

Dr Simon Longstaff (The Ethics Centre Sydney

Our core business value is our professional expertise. Our primary business objective is to be a "trusted adviser".


Co Serve incorporates responsible business practices in all operations.

We recognise the important role businesses play in the community fostering fair and just social and economic conditions. This includes the identification and adoption of appropriate environmental, economic and social goals.

More information on our environmental, economic and social activities can be found here.

Quality Management

Co Serve is committed to the active management of quality concerns.

' I have made this letter longer than usual, only because I have not had the time to make it shorter '

Blaise Pascal

Accordingly, in delivering professional services, we draw on a set of standard processes, and a related suite of standard procedures and concise documents, that can be accurately tailored to the requirements of each engagement.

We have developed a Quality Systems Manual, consistent with the quality requirements of ISO 9001, setting out these processes, procedures and documents.

Service Delivery

Our approach to service delivery is project management based and consistent with the principles embodied in the Project Management Institute's (PMI) Project Management Body of Knowledge (PMBoK).

We employ a suite of work management tools to manage work schedules, resource availability, activities and work products; to monitor performance and communicate progress; and to collect billing data and substantiate invoicing.

Professional Associations & Independence

Management theory, economics, information and communication technologies are all complex and constantly changing knowledge domains. As a result Co Serve maintains a network of specialist consultants, professional associates and key technology partners to support delivery of comprehensive, up-to-date and cost effective consulting services. 

In our reports and written advice any references made to the products and service offered by our professional associates and key partners do not necessarily imply endorsement, nor do they imply criticism of products and services not mentioned.
