 This section of the UNTP-CRM project website describes how interested parties can undertake a UNTP-CRM implementation. At this stage of the project, in which UNTP-CRM is still being developed, implementers will be testing draft deliverables and providing feedback to the Project Team. Testing and feedback will enable refinement of deliverables for usability and practicality, and facilitate global scalability, which are principles of the project. 
 
+### Design Principles 
+
+This document is guided by the following principles
+1. Simple and implementable always wins over expansive & complex.
+2. Open and free is a fundamental requirement.
+3. Collaborative development encourages buy-in
+4. Decentralised models will always be more scalable than centralized ones.
+5. Independently verifiable claims are more credible.
+6. Learn and leverage existing ecosystems, methodologies, standards and approaches.
+
+### Design Challenges
+
+Implementing end-to-end supply chain traceability at scale faces a number of challenges. 
+
+Challenge | Our approach 
+-- | --
+A plethora of platforms exist already | We must focus on interoperability between systems, not picking winners. We’ll also provide guidance on how existing systems can extend their capability to support interoperability. 
+Technology maturity is variable | We must accommodate small businesses and developing nations and allow a gradual transition from paper processes.
+Most traceability pilots have not scaled to production volumes | We must design simple and scalable solutions that can be implemented at scale
+Supply chain actors will not expose sensitive data | We must allow stakeholders to protect sensitive commercial information whilst revealing ESG info.
+ESG claims have different levels of trust | We must provide sufficient evidence to trust the claims.
+Greenwashing fraud is endemic | We need to explicitly identify greenwashing fraud vectors and how to solve them – including product substation, mass balance, etc. In particular, in CRM, suppliers have taken the approach of inserting a middleman and obscuring the traceability to the source. A goal of this approach must be the traceability of claims back to the point of extraction, as required by the OECD due diligence handbook.
+Cost | The solution must be cheap enough that there remains a plentiful margin incentive for producers and manufacturers to change behaviour.
