Design to Cost & Invest to Cost

COST HOUSE expertise, now integrated into MASAÏ

Our projects combine consulting expertise and dedicated tools, supported by VALOPTIA, a software solution from the group.

−22% cost price: optimize where 80% of costs are determined

Design to Cost and Invest to Cost make it possible to optimize the costs of your products and investments from the design phase, where 80% of costs are committed. Our approach combines technical analysis, value analysis, cross-functional workshops, technology benchmarking, and governance support for concrete results: 15 to 25% reduction in product costs and 20 to 50% savings on CAPEX, with a methodological transfer to sustain the approach.

  • Are you optimizing your costs where the leverage is greatest — right from the design stage?
