Clever engineers are usually able to pick up basic supply chain management capabilities. At least as long as it's about suppliers of things in their technical domain.

For non-technical supply chain managers to pick up enough technical chops to understand the stuff they are supposed to manage the supply chain of is comparatively more difficult.

Especially when fierce negotiations to push the price down are not the highest priority, but robustness of supply chains, having alternative options that technically work, and ensuring quality according to tight specs are paramount. Which is how I assume ASML supply chain management to work.
