  • Ensure wafer plans reflect contractual commitments, lead times, and risk profiles across foundry partners.

Governance, Analytics & Communication
  • Establish clear governance, metrics, and review cadences for wafer planning performance (utilization, coverage, backlog risk, and cost).
  • Lead executive-level reviews of wafer supply outlook, risks, and mitigation plans.
  • Build scalable planning processes, tools, and analytics to improve visibility and decision quality.

Team Leadership
  • Lead and develop the global wafer planning organization, setting clear ownership, decision rights, and accountability.
