Consulting is defined as the practise of providing a third party with expertise on a matter in exchange for a fee. The service may involve either advisory or implementation services. For the consultant, taking an independent and unbiased stance on an issue is central to his/her role. A consultant can, in principle, service any sector. Over the past few decades, however, the term has become synonymous with business advisory – which focuses mostly on business strategy, management, organisation, operational processes and technology.
