Industrial sector or secondary sector is one of the 3 sectors that make up a country's economy. The other two are the primary sector (includes agriculture, fishing, and mining) and service sector (includes hospitality, consultancy and nursing). Secondary sector is one that makes a complete product which can then be utilized. Examples of industrial sector are manufacturing industry and construction.
Industrial sector usually accepts the primary sector end product and then applies them to construct completed products that are then either purchased by the end user or sent for further processing or fabrication. The industrial or secondary sector can be classified into two types: heavy industry and light industry. Most industries transform raw materials into finished products. Large quantities of energy are consumed to run the process. Manufacturing industries tend to generate pollution and are the source of environmental problems.
Construction is making a building or the fabrication of infrastructure. Effective planning is required for successful execution. The activity requires a mastery of multitasking.
