Episode notes
Build Procurement For Long Term Strategic Impact
- Build procurement with a medium-to-long term orientation focused on organization and digital platforms rather than short-term fixes.
- Tomas emphasizes defining an aim first, then securing investments in platforms, suppliers, or people to move beyond current capabilities.
Strategic Sourcing Is Splitting From P2P
- Strategic sourcing is separating from P2P and transaction execution as GBS and centers handle operational work.
- Tomas says this separation frees strategic teams to focus on higher-value sourcing and business solutions.
Decisioning Platforms Shift Procurement Forward
- Decisioning platforms give procurement forward-looking visibility across contracts, volumes, pricing trends and usage.
- Tomas links these platforms to cross-stakeholder views so teams can see renewals, usage and optimize demand beyond historical spend reports.
