Knowledge process outsourcing (KPO) is a form of outsourcing that is less structured and more specialized than business process outsourcing (BPO). KPO deals largely in services that are highly "knowledge-based", such as: intellectual property research for patent applications; legal and medical services; training, consultancy, and research and development in fields such as pharmaceuticals and biotechnology; and animation and design. It is being claimed that KPO is one step extension of Business Processing Outsourcing (BPO) because BPO Industry is shaping into Knowledge Process Outsourcing because of its favorable advantageous and future scope. But, let us not treat it only a 'B' replaced by a 'K'. In fact, Knowledge process can be defined as high added value processes chain where the achievement of objectives is highly dependent on the skills, domain knowledge and experience of the people carrying out the activity. And when this activity gets outsourced a new business activity emerges, which is generally known as Knowledge Process Outsourcing.

Knowledge Processing Outsourcing (popularly known as a KPO), calls for the application of specialized domain pertinent knowledge of a high level. The KPO typically involves a component of Business Processing Outsourcing (BPO), Research Process Outsourcing (RPO) and Analysis Proves Outsourcing (APO). KPO business entities provide typical domain-based processes, advanced analytical skills and business expertise, rather than just process expertise. KPO Industry is handling more amount of high skilled work other than the BPO Industry. While KPO derives its strength from the depth of knowledge, experience and judgment factor; BPO in contrast is more about size, volume and efficiency.

In fact, it is the evolution and maturity of the Indian BPO sector that has given rise to yet another wave in the global outsourcing scenario: KPO or Knowledge Process Outsourcing. The success achieved by many overseas companies in outsourcing business process operations to India has encouraged many of the said companies to start outsourcing their high-end knowledge work as well. Cost savings, operational efficiencies, availability of and access to a highly skilled and talented workforce and improved quality are all underlying expectations in outsourcing high-end processes to India

The future of KPO has a high potential as it is not restricted to only Information Technology (IT) or Information Technology Enabled Services (ITES) sectors and includes other sectors like Legal Processes, Intellectual Property and Patent related services, Engineering Services, Web Development application, CAD/CAM Applications, Business Research and Analytics, Legal Research, Clinical Research, Publishing, Market Research (Market research KPO) etc. In the future, it is envisaged that KPO has a high potential as it is not restricted only to Information Technology (IT) or Information Technology Enabled Services (ITES) sectors, and includes other sectors like Intellectual Property related services, Business Research and Analytics, Legal Research, Clinical Research
