ABSTRACT

The industrial landscape can be broadly divided into three sectors. The primary sector comprises industries that procure raw materials (e.g., mining industry, oil, and gas extraction industry). The industries in the secondary sector are concerned with the manufacturing of finished products using raw materials (e.g., automobile industry, computer industry). Unlike the primary and secondary industries, which deliver tangible products, the defining characteristic of the tertiary sector is that industries in this sector produce intangible entities called services. The tertiary sector is also called the service sector [Weber and Burri 2013].
