Biotechnology consulting: Biotechnology consulting (or biotech consulting) refers to the practice of assisting organizations involved in research and commercialization of biotechnology in improving their methods and efficiency of production, and approaches to R&D.  This assistance is usually provided in the form of specialized technological advice and sharing of expertise.  Both start-up and established organizations would hire biotechnology consultants mainly to receive an independent and professional advice from key opinion leaders, individuals with extensive knowledge and experience in a particular area of biotechnology or biological sciences, and, often, to outsource their projects for implementation by well qualified individuals.  Large management consulting firms would often be able to provide technological advice as well, depending on the qualifications of their consulting team.  With the growth of pharmaceutical companies, biotechnology consulting has recently developed into an industry of its own and separated from the management consulting industry that traditionally also provides technological advice on R&D projects to various industries.  This has also been fueled by the impact various conflicts of interests can have on commercialization when biotechnology organizations contract services from academic institutions or government scientists
