Weele and Rozemeijer (1996) define "procurement" as including all activities required in
order to obtain the product from the supplier and get it to the place it is consumed.
According to An Thi Thanh Nhan (2018), ‘Procurement’ is defined as an activity done by
companies to create inputs. Procurement is also known as sourcing, drafting supply
contracts as well as conducting inventory management.
Regarding purchasing strategies, according to Janda & Seshadri (2001), a purchasing
strategy has a great influence on the performance of companies. In order to ensure their
performance, it is essential for companies to first assess the current supply and then to
develop a strategy for obtaining resources.
Regarding organizational structures within purchasing, Peter Baily et al. (2005) argue
that there is no ideal structure that can be applied by companies forever. In case of any
arising change in the business environment and in case where companies grow more and
more, it is required to re-evaluate and change the organisational structures within
purchasing. Once organizational strategies are correctly formulated, the roles and objectives
of procurement/purchasing will be clearly defined..
2.2. Studies on supply management
Supply management has been considered an important factor for a long time because
it allows companies to increase their revenue and reduce their costs. David Burt et al. (2010)
identify that supply management has the following roles: (1) Creativity which means
creating new design ideas for products through research and development, (2) Finance
which means supply management, including: managing, making financial plans and
controlling financial aspects of a company, (3) Human resource which means the
management of labor supply and relationships with employees, (4) Raw materials supply
which means the management of procurement of raw materials, services and necessary
equipment, (5) Production which means the management of producing products and
services with economic value from purchased raw materials, (6) Distribution which means
the management of marketing and selling products and services to the market.
After identifying how supply management can affect company profits, Waters and
Donal (2011) consider supply chain management to be a difficult task because it contains a
lot of risks, from small risks which can result in delays to big risks which can disrupt the
entire supply chain.
2.3. Studies on raw materials management
Raw materials management can be defined as the function of business that is
responsible for the coordination of planning, sourcing, purchasing, moving, storing and
controlling raw materials in an optimum manner so as to provide services to customers at a
minimum cost. Raw materials management enables companies to coordinate raw materials-
related activities and control total raw materials costs through integrated systems. The raw
