[00:01:53] Emma discusses Microsoft’s multi-tier approach to metrics, focusing on maintainers’ value to products and communities, component intelligence, and engineering standards on GitHub.
[00:04:06] James elaborates on his focus on GitHub metrics, the development of policy and tooling for security, and simplifying developers’ workflow.
[00:04:51] Justin categorizes metrics into those for maintainers, for management, and for developers making decisions on dependencies. He talks about challenges in managing the scale of data from 13,000 repositories and the importance of security metrics.
[00:05:37] Emma discusses an experiment with the OpenSSF scorecard for repository security and the effort to motivate improvements in this area. She highlights the challenges of instilling these practices as part of the culture.
[00:07:30] Justin sees opportunities to combine CHAOSS metrics with secure supply chain efforts, aiming to aid developers in making informed decisions about dependencies and warning them of potential risks.
[00:09:11] Dawn asks about the challenges of scaling metrics and managing the vast number of dependencies. Justin responds by describing an experience focused on aiding developers at the start of a project, helping them make data-informed choices about a few key dependencies.
[00:12:51] Emma adds that from the Open Source Programs Office (OSPO) perspective, having a dashboard to direct inquiries is very helpful. James mentions that the dashboard also provides an easy way to surface security guidance.
[00:13:27] The conversation shifts to Dawn asking about the business aspect of open source within Microsoft and how they measure this impact. James responds that open source is integral to Microsoft’s software development approach, aiming to build an internal community and avoid duplicating solutions. He also discusses the importance of Software Bill of Materials (SBOMs) for security and supply chain transparency.
[00:16:00] Emma elaborates on the internal value of external open source contributions, sharing how they help maintainers demonstrate the business impact during reviews.
[00:17:14] Dawn inquiries about the future direction for Microsoft regarding metrics and measurement. Justin touches on exploring the area of funding, aiming to improve conversations about financial contributions to open source projects and achieving better return on investment.
