Your challenges and opportunities deserve an experienced (Procurement) Leader

Driving Performance

Immediate Expertise. Impact & Value. End to End

Let's talk. It's free.

In cases of absence, resignation, or open positions: short-notice takeover of leadership and strategic roles in procurement (Head of Procurement, Category Manager, Project Procurement) — without long-term commitment.

Developing appropriate organizational structures, creating meaningful and precise KPIs, improving interfaces, collaboration, and process quality.

Guiding and leading structural changes, managing procurement teams, stabilizing teams during crises, building and implementing strategies.

Analyzing spend & cost structures, identifying savings potential, implementing cost reduction measures, and improving contract management.

Stabilizing teams and processes during critical phases and amid supply shortages and material price fluctuations; diversifying supplier portfolios; setting up risk management processes and ensuring continuity. Conducting risk assessments, supplier monitoring, supplier switches, or dual sourcing.

Digitalizing across the entire procurement organization; planning and leading digitalization projects; introducing new systems (eProcurement/SRM solutions, AI and risk management systems); selection processes and contribution of know-how on market trends and technologies. Concepts and strategies for digital architecture, data management, and process automation.

Managing strategic projects such as post-merger integration, procurement reorganization, introduction of new category strategies, global sourcing initiatives, and diversification.

Analyzing and optimizing procurement processes, identifying inefficient structures, and implementing improvements that take effect quickly.

New procurement processes and risk management structures are required; creating ESG integration in procurement, compliance structures, and transparency.

Coaching the procurement team, transferring knowledge, implementing best practices for the sustainable strengthening of the organization and its people.
