SERVICES
From the structured definition of target costs to their consistent realization in the product: We combine cost understanding, technology, and implementation expertise to make products more economical, more competitive, and more valuable.
Specification Optimization
With our AI-supported approach, we streamline historically grown specifications and reduce costs through the targeted reduction of over-specification.
Digital Cost and Value Engineering
We digitize cost and value analysis processes – from robust cost models to AI-supported evaluation of technical product data.
Cost reduction initiatives
We develop and implement structured cost-down programs – from potential hypotheses to measurable implementation with suppliers and internal teams.
Eco-design
We combine material, cost, and sustainability assessments to develop eco-design solutions that are technically feasible and economically viable.
Supply Chain Optimization
We make supply chains, sourcing options, and risks transparent – providing the basis for better decision-making in purchasing, engineering, and management.
