It’s no secret that digital transformation has been essential to the procurement function’s rise as a true strategic partner to business operations, enabling efficiencies, operational resilience, and organisational overhauls that deliver consistent and reliable output.

There are few better examples of procurement and supply chain’s transformation from back-office function to strategic imperative than at oil and petrochemical company Tüpraş, the largest industrial enterprise in Turkey that operates four refineries located in İzmit, İzmir, Kırıkkale, and Batman, with a total annual crude oil processing capacity of over 30 million tonnes. Since its privatisation in 2006, as Koç Holding’s leading company in energy sector, its success has been supported by the contributions of its overhauled procurement function.
Tüpraş’s procurement function has played a pivotal role in adopting innovative technologies, while its long-term strategies concerning ESG initiatives and further advancements in technology are also deeply reliant on this function. Effectively capturing, harnessing, and fostering the potential of procurement across such an extensive business operation is an immense challenge. Keen to learn more about the leadership behind Tüpraş’s procurement-focused successes, SupplyChainStrategy sat down with four key players in the company’s roster.
