Value chain 

Michael Porter (1995) introduced the notion of a value chain in his book “Competitive Advantage: Creating and Sustaining Superior Performance”. The concept of value added, in the form of the value chain, can be used to develop an organisation’s sustainable competitive advantage in the business field of the 21st Century. All organisations consist of activities that link together to develop the value of the business, and together these activities form the organisation’s value chain. Such activities may include purchasing activities, manufacturing the products, distribution and marketing of the company’s products and activities.
