Without inventory data…

You can have the perfect method… but…

You have no results to use… (aka your method is useless…)

Expanding the range of applications Imagine :

  You have one product with 50 ingredients and suppliers Identification of the main hot spots / questions to ask in a few hour

  You want to assess your overall company’s water footprint, with   50 business units   200 sites   1’000 products   5’000 suppliers

Identification of the main hot spots / questions to ask in a few days

Comprehensive assessment of your company water footprint including your supply chain

Significant improvement in your capacity to prioritize your resources
