ABSTRACT
Law firms, accounting firms, and other professional service firms have always been pure knowledge businesses, always conscious of the fact that their sustainable advantage is the expertise and knowledge of their consultants, and their firms, rather than any physical factors of service production (Susskind, 2013). The growing awareness of knowledge and its value in organizations from the last decade of the 20th century, coupled with the changes in the business environment, has resulted in progressive firms finding alternative ways of providing cost-efficient and high-quality services that may sharpen their competitiveness and broaden their influence within the investigation services industry and the global economy.
