A value chain is a progression of activities that a firm operating in a specific industry performs in order to deliver a valuable product (i.e., good and/or service) to the end customer. The concept comes through business management and was first described by Michael Porter in his 1985 best-seller, Competitive Advantage: Creating and Sustaining Superior Performance.[1]

The idea of the value chain is based on the process view of organizations, the idea of seeing a manufacturing (or service) organization as a system, made up of subsystems each with inputs, transformation processes and outputs. Inputs, transformation processes, and outputs involve the acquisition and consumption of resources – money, labour, materials, equipment, buildings, land, administration and management. How value chain activities are carried out determines costs and affects profits.

According to the OECD Secretary-General (Gurría 2012),[3] the emergence of global value chains (GVCs) in the late 1990s provided a catalyst for accelerated change in the landscape of international investment and trade, with major, far-reaching consequences on governments as well as enterprises (Gurría 2012).[3]


Michael Porter's value chain

The appropriate level for constructing a value chain is the business unit,[4] not division or corporate level. Products pass through a chain of activities in order, and at each activity the product gains some value. The chain of activities gives the products more added value than the sum of added values of all activities.[4]

The activity of a diamond cutter can illustrate the difference between cost and the value chain. The cutting activity may have a low cost, but the activity adds much of the value to the end product, since a rough diamond is significantly less valuable than a cut diamond. Typically, the described value chain and the documentation of processes, assessment and auditing of adherence to the process routines are at the core of the quality certification of the business, e.g. ISO 9001.[citation needed]

A firm's value chain forms a part of a larger stream of activities, which Porter calls a value system.[citation needed] A value system, or an industry value chain, includes the suppliers that provide the inputs necessary to the firm along with their value chains. After the firm creates products, these products pass through the value chains of distributors (which also have their own value chains), all the way to the customers. All parts of these chains are included in the value system. To achieve and sustain a competitive advantage, and to support that advantage with information technologies, a firm must understand every component of this value system.[citation needed]

Primary activities

All five primary activities are essential in adding value and creating a competitive advantage and they are:

Companies can harness a competitive advantage at any one of the five activities in the value chain. For example, by creating outbound logistics that are highly efficient or by reducing a company's shipping costs, it allows to either realize more profits or pass the savings to the consumer by way of lower prices.[5]

Using support activities helps make primary activities more effective. Increasing any of the four support activities helps at least one primary activity to work more efficiently.

Virtual value chain

The virtual value chain, created by John Sviokla and Jeffrey Rayport,[6] is a business model describing the dissemination of value-generating information services throughout an Extended Enterprise. This value chain begins with the content supplied by the provider, which is then distributed and supported by the information infrastructure; thereupon the context provider supplies actual customer interaction. It supports the physical value chain of procurement, manufacturing, distribution and sales of traditional companies.

An industry value-chain is a physical representation of the various processes involved in producing goods (and services), starting with raw materials and ending with the delivered product (also known as the supply chain). It is based on the notion of value-added at the link (read: stage of production) level. The sum total of link-level value-added yields total value. The French Physiocrats' Tableau économique is one of the earliest examples of a value chain. Wassily Leontief's input-output tables, published in the 1950s, provide estimates of the relative importance of each individual link in industry-level value-chains for the U.S. economy.

Global value chains

Main article: Global value chain

Cross border / cross region value chains

Often multinational enterprises (MNEs) developed global value chains, investing abroad and establishing affiliates that provided critical support to remaining activities at home. To enhance efficiency and to optimize profits, multinational enterprises locate "research, development, design, assembly, production of parts, marketing and branding" activities in different countries around the globe. MNEs offshore labour-intensive activities to China and Mexico, for example, where the cost of labor is the lowest (Gurría 2012).[3] The emergence of global value chains (GVCs) in the late 1990s provided a catalyst for accelerated change in the landscape of international investment and trade, with major, far-reaching consequences on governments as well as enterprises.(Gurría 2012)[3]

Global value chains in development

Through global value chains, there has been a growth in interconnectedness as MNEs play an increasingly larger role in the internationalisation of business. In response, governments have cut corporate income tax rates or introduced new incentives for research and development to compete in this changing geopolitical landscape (LeBlanc, Matthews & Mellbye 2013, p. 6).[7]

In an (industrial) development context, the concepts of global value chain analysis were first introduced in the 1990s (Gereffi et al.)[8] and have gradually been integrated into development policy by the World Bank, Unctad,[9] the OECD and others.

Value chain analysis has also been employed in the development sector as a means of identifying poverty reduction strategies by upgrading along the value chain.[10] Although commonly associated with export-oriented trade, development practitioners have begun to highlight the importance of developing national and intra-regional chains in addition to international ones.[11]

For example, the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) has investigated strengthening the value chain for sweet sorghum as a biofuel crop in India. Its aim in doing so was to provide a sustainable means of making ethanol that would increase the incomes of the rural poor, without sacrificing food and fodder security, while protecting the environment.[12]


The value chain framework quickly made its way to the forefront of management thought as a powerful analysis tool for strategic planning. The simpler concept of value stream mapping, a cross-functional process which was developed over the next decade,[13] had some success in the early 1990s.[14]

The value-chain concept has been extended beyond individual firms. It can apply to whole supply chains and distribution networks. The delivery of a mix of products (goods and services) to the end customer will mobilize different economic factors, each managing its own value chain. The industry wide synchronized interactions of those local value chains create an extended value chain, sometimes global in extent. Porter terms this larger interconnected system of value chains the "value system". A value system includes the value chains of a firm's supplier (and their suppliers all the way back), the firm itself, the firm distribution channels, and the firm's buyers (and presumably extended to the buyers of their products, and so on).

Capturing the value generated along the chain is the new approach taken by many management strategists. For example, a manufacturer might require its parts suppliers to be located nearby its assembly plant to minimize the cost of transportation. By exploiting the upstream and downstream information flowing along the value chain, the firms may try to bypass the intermediaries creating new business models, or in other ways create improvements in its value system.

The Supply-Chain Council, a global trade consortium in operation with over 700 member companies, governmental, academic, and consulting groups participating in the last 10 years, manages the Supply-Chain Operations Reference (SCOR), the de facto universal reference model for Supply Chain including Planning, Procurement, Manufacturing, Order Management, Logistics, Returns, and Retail; Product and Service Design including Design Planning, Research, Prototyping, Integration, Launch and Revision, and Sales including CRM, Service Support, Sales, and Contract Management which are congruent to the Porter framework. The SCOR framework has been adopted by hundreds of companies as well as national entities as a standard for business excellence, and the U.S. Department of Defense has adopted the newly launched Design-Chain Operations Reference (DCOR) framework for product design as a standard to use for managing their development processes. In addition to process elements, these reference frameworks also maintain a vast database of standard process metrics aligned to the Porter model, as well as a large and constantly researched database of prescriptive universal best practices for process execution.
