# Supply Chain Integrity WG
## Objective
The objective of the Supply Chain Integrity Working Group (WG) is to provide a global community for collaborating to help individuals and organizations assess and improve the security of end-to-end supply chains for open source software.
## Motivation
Supply chain issues and attacks cause significant damage worldwide including lost revenue, costs of ransomware payments, costs of mitigation, denial of access to resources, reduced customer trust, and public deception. As a matter of public trust, governments are beginning to mandate actions aimed at improving the security and integrity of supply chains. The [US White House Executive Order on Improving the Nation’s Cybersecurity](https://www.whitehouse.gov/briefing-room/presidential-actions/2021/05/12/executive-order-on-improving-the-nations-cybersecurity/) is one such example.
## Communications
