Our procurement processes and what we source from suppliers

How we select our suppliers

Given the critical role suppliers and partners play in our operations, NOS places particular importance on both the selection process and the quality of the relationships it establishes with them.

Procurement Manual

Our Procurement Manual ensures the adoption of best practices throughout the procurement process. It sets out clear rules and guiding principles for supplier consultation, contract awarding and process oversight. This approach supports careful risk management, maximises value creation, and helps foster strong, long-term relationships.

 

Supplier Selection

Supplier selection is based on objective criteria, taking into account technical and economic considerations, as well as compliance with applicable requirements and certifications. The process is supported by a reputable electronic platform, widely recognised in the market.

 

Ongoing Monitoring

At the end of each formalisation process, a survey is conducted with technically qualified suppliers to assess their satisfaction with the negotiation process, the quality of the information provided, and the ease of use of the procurement platform.

 

Performance Evaluation

We assess criteria related to ethical conduct, environmental responsibility, occupational health and safety, timeliness, and the quality of materials or services provided by our suppliers. This allows us to identify potential risks associated with each engagement.
