CHAOSS Value Metrics Group (VMG)

Read our Launch Plan

VMG is a new group, focused on metrics for Economic Value in open source.

Economic value is expressed in different ways for different types of stakeholders. We will be exploring this space in the coming months.

See our launch plan for more info.

This CHAOSS working group is using the general CHAOSS mailing list.

Join our Weekly Calls

The VMG team meets every Friday from 9-10 Pacific Time. All are welcome.

Problem Statement

We have gotten requests from community members to establish industry-standard metrics for economic value in open source. Lack of metrics makes it difficult for business decision makers to compare open-source methods to alternatives. Lack of metrics makes it difficult to allocate resources optimally across projects, slowing decision making and product innovation.


We believe that value metrics can accelerate the adoption of open source methods within industry, providing more opportunities for developers to make a living wage in open source.


Between March 2019 and September 2019 we will execute a launch plan with limited goals:

Identify Stakeholders and Validate Interest

  • Identify market segments and stakeholders
  • Understand Who cares about Open Source Value (and why)
  • Specify and prioritize Key Performance Indicators
  • Calculate potential aggregate economic value

Grow hands-on community

  • CHAOSS Members: Consultants, researchers, grant writers
  • Project Stakeholders: Sponsors, maintainers, contributors, consumers

Build reusable assets

  • Repeatable methodology for discovering value
  • MVP Tooling with Development Roadmap

In the long term, we’d like to publish trusted industry-standard Value Metrics. A kind of S&P for software development, an authoritative source for metrics significance and industry norms.

Focus Areas

Focus Area Goal
1. Labor Investment Estimating the labor investment in open source projects.
2. Innovation Value Evaluating open source project development for comparing with in-house and outsourcing options.
3. Downstream Value Estimate the value provided to other open source projects.
4. Ecosystem Value Estimating the value of an open source project’s ecosystem.
5. Living Wage Expanding opportunities for people to make a living wage in open source.
