Yes, I agree with the statement that "Nando's forms collaborative supplier relationships with their suppliers."

Two examples from the case study that support this argument are:

Nando's has a long$-$term relationship with its chicken supplier, Rainbow, which has been its partner for over $20$ years. This relationship is based on trust, transparency, and mutual benefits. Nando's shares its growth plans with Rainbow, and Rainbow invests in new technologies and infrastructure to meet Nando's demands. This partnership has resulted in a stable supply chain, improved product quality, and cost savings for both parties.

Nando's also has a close relationship with its peri$-$peri sauce supplier, Fogo, which has been its partner for over $30$ years. Nando's and Fogo work together to develop new recipes and flavors, and Fogo provides training and support to Nando's staff. This collaboration has led to the creation of unique and authentic products that differentiate Nando's from its competitors and enhance its brand image.

These examples demonstrate that Nando's values its supplier relationships and works collaboratively with them to achieve mutual goals. By building trust, sharing knowledge, and aligning interests, Nando's creates a win$-$win situation for both parties and strengthens its supply chain resilience and competitiveness.

Final Answer: Yes, Nando's forms collaborative supplier relationships with their suppliers, as evidenced by its long$-$term partnerships with Rainbow and Fogo, which are based on trust, transparency, and mutual benefits. These collaborations have resulted in improved product quality, cost savings, and unique and authentic products that differentiate Nando's from its competitors and enhance its brand image.
