 “THESIS is instrumental in helping Georgia-Pacific communicate with our retail customers. Answering several different assessments at a time is a drain on our time and resources. THESIS not only makes it easy for us to answer one assessment for multiple retail customers, but the consistency across thequestions asked year-to-year also helps us measure our progress.” Georgia-Pacific

In 2019, TSC partnered with SupplyShift to create our current iteration of THESIS, powered by SupplyShift’s cutting edge platform and informed by TSC’s deep roots in higher education, including ASU and Wageningen University + Research. THESIS currently has more retail users than ever before.

What is the Science Behind THESIS?

THESIS is rooted in TSC’s university-based, scientific methodology. THESIS is based in LCA methodology and was developed in a pre-competitive way using TSC’s stakeholder engagement expertise that brings the CPG industry, NGOs, and higher education together for greater impact. It is this combination of stakeholders that sets THESIS apart from other consultant-led performance assessment platforms.  

TSC methodology is based on creating and evolving strict, LCA-based key performance indicators using relevant sources and evidence for hotspots.
