any association of individuals or organizations, usually formally organized, that, on the basis of one or more shared concerns, attempts to influence public policy in its favour. All interest groups share a desire to affect government policy to benefit themselves or their cause. It could be a policy that exclusively benefits group members or one segment of society (e.g., government subsidies for farmers) or a policy that advances a broader public purpose (e.g., improving air quality). Interest groups are a natural outgrowth of the communities of interests that exist in all societies, from the narrowest groups such as the Japan Eraser Manufacturers Association to broader groups such as the AFL-CIO to very broad organizations such as the military in authoritarian countries. Interest groups exist at all levels of government—national, state, provincial, and local—and increasingly they have occupied an important role in international affairs.

Since its inception in 1998, the Bluetooth SIG is primarily run by a volunteer staff from its member companies. In 2001 Tom Siep served as the group's Managing Director and from 2002-2004 Mike McCamon led the group as its Executive Director. In 2004 he was replaced by Michael W. Foley (Mike). Beginning in 2002 a professional staff was hired, composed of operations, engineering and marketing specialists. From 2002-2004 the Bluetooth SIG was based in Overland Park, Kansas USA and is now based in Bellevue, Washington with additional offices in Malmö, Sweden and Hong Kong, China. In addition to its professional staff, the SIG still relies on many volunteers from member companies who participate in the various working groups that produce the standardization documents and oversee the qualification process for new products.

The Corporate Groups are simply the Board of Directors and the professional staff of the SIG.
Participation in the Expert Groups is restricted to Promoter members and Associate members.
Participation in the Working Groups is restricted to Promoter members and Associate members.
(UnPlugFest is an annual event at which manufacturers are invited to confidentially test their mutual interoperability)
Probably most significant among them is the Qualification Review Board since this body specifies the manner in which manufacturers must go about complying with the Bluetooth specifications before they are allowed to Bluetooth-brand their products and sell them.
Each Promoter member has one seat (and one vote) on the Board of Directors and the Qualification Review Board (the body responsible for overseeing the qualification process). They each have hundreds of staff in the various working groups and committees that comprise the work of the SIG.
Associate members paying the full fee have early access to draft specifications and to work with other Associate and Promoter members on enchancing existing specifications. They are also able to review specifications before their publication and have voting rights in the working groups and committees as well as being able to make keynote speeches at industry conferences. Those Associate members who pay the discounted fee retain the document access rights but are not allowed to participate in the working groups and thus have considerably less influence on the standardization processes. The SIG's website carries a full list of Associate members
If these tests are all passed, the device progresses to the Category A tests. These must be carried out at recognised Bluetooth Qualification Test Facilities, of which there are currently only 20 in the world
As of 2005, this testing process costs $10 000 for Adopter members and $5 000 for Associate members and Promoter members. These test facilities use equipment developed specifically for the purpose, and are approved on behalf of the Qualifications Review Board by a Bluetooth Technical Assessor (BTA). These assessors are individuals who are experienced with such laboratory assessment procedures and who can demonstrate their understanding of the technical requirements of Bluetooth. The SIG currently contracts with accreditation organizations to carry out the process of selecting and training Assessors, with the Qualifications Review Board giving the eventual formal approval.
Once a device has passed all the Category A, B and C tests to the satisfaction of a BQB, it is allowed to be marketed as a Bluetooth device using the Bluetooth trademarks.
