Industry is the production of goods or related services within an economy. The major source of revenue of a group or company is the indicator of its relevant industry. When a large group has multiple sources of revenue generation, it is considered to be working in different industries. Manufacturing industry became a key sector of production and labour in European and North American countries during the Industrial Revolution, upsetting previous mercantile and feudal economies. This came through many successive rapid advances in technology, such as the production of steel and coal.
Following the Industrial Revolution, possibly a third of the world's economic output are derived that is from manufacturing industries. Many developed countries and many developing/semi-developed countries (People's Republic of China, India etc.) depend significantly on manufacturing industry. Industries, the countries they reside in, and the economies of those countries are interlinked in a complex web of interdependence.
Industries can be classified in a variety of ways. At the top level, industry is often classified according to the three-sector theory into sectors: primary (extractive), secondary (manufacturing), and tertiary (services). Some authors add quaternary (knowledge) or even quinary (culture and research) sectors. Over time, the fraction of a society's industry within each sector changes.
Below the economic sectors there are many other more detailed industry classifications. These classification systems commonly divide industries according to similar functions and markets and identify businesses producing related products.
Industries can also be identified by product, such as: construction industry, chemical industry, petroleum industry, automotive industry, electronic industry, power engineering and power manufacturing (such as gas or wind turbines), meatpacking industry, hospitality industry, food industry, fish industry, software industry, paper industry, entertainment industry, semiconductor industry, cultural industry, and poverty industry.
ISIC is a standard classification of economic activities arranged so that entities can be classified according to the activity they carry out. The categories of ISIC at the most detailed level (classes) are delineated according to what is, in most countries, the customary combination of activities described in statistical units, considering the relative importance of the activities included in these classes.
While ISIC Rev.4 continues to use criteria such as input, output and use of the products produced, more emphasis has been given to the character of the production process in defining and delineating ISIC classes.Industry is very important.
The Industrial Revolution led to the development of factories for large-scale production, with consequent changes in society. Originally the factories were steam-powered, but later transitioned to electricity once an electrical grid was developed. The mechanized assembly line was introduced to assemble parts in a repeatable fashion, with individual workers performing specific steps during the process. This led to significant increases in efficiency, lowering the cost of the end process. Later automation was increasingly used to replace human operators. This process has accelerated with the development of the computer and the robot.
Historically certain manufacturing industries have gone into a decline due to various economic factors, including the development of replacement technology or the loss of competitive advantage. An example of the former is the decline in carriage manufacturing when the automobile was mass-produced.
A recent trend has been the migration of prosperous, industrialized nations towards a post-industrial society. This is manifested by an increase in the service sector at the expense of manufacturing, and the development of an information-based economy, the so-called informational revolution. In a post-industrial society, manufacturers relocate to more profitable locations through a process of off-shoring.
Measurements of manufacturing industries outputs and economic effect are not historically stable. Traditionally, success has been measured in the number of jobs created. The reduced number of employees in the manufacturing sector has been assumed to result from a decline in the competitiveness of the sector, or the introduction of the lean manufacturing process.
Related to this change is the upgrading of the quality of the product being manufactured. While it is possible to produce a low-technology product with low-skill labour, the ability to manufacture high-technology products well is dependent on a highly skilled staff.
An industrial society can be defined in many ways. Today, industry is an important part of most societies and nations. A government must have some kind of industrial policy, regulating industrial placement, industrial pollution, financing and industrial labour.
In an industrial society, industry employs a major part of the population. This occurs typically in the manufacturing sector. A labour union is an organization of workers who have banded together to achieve common goals in key areas such as wages, hours, and other working conditions. The trade union, through its leadership, bargains with the employer on behalf of union members (rank and file members) and negotiates labour contracts with employers. This movement first rose among industrial workers.
The Industrial Revolution changed warfare, with mass-produced weaponry and supplies, machine-powered transportation, mobilization, the total war concept and weapons of mass destruction. Early instances of industrial warfare were the Crimean War and the American Civil War, but its full potential showed during the world wars. See also military-industrial complex, arms industry, military industry and modern warfare.
