The document discusses a training session focused on improving data sharing between Sainsbury's and its suppliers. It outlines an agenda to help participants envision an ideal future state where data sharing is commonplace ("Datopia"), map out the specific types of data that could be shared to achieve this vision, discuss potential roadblocks to increased sharing, select a pilot dataset to increase sharing, and identify the key stakeholders needed to implement changes. The overall goal is to identify a realistic project that demonstrates quantifiable benefits from improved inter-organizational data sharing.
