Quansight Labs Blog: Community-driven open source and funded development

Quansight Labs is an experiment for us in a way. One of our main aims is to channel more resources into community-driven PyData projects, to keep them healthy and accelerate their development. And do so in a way that projects themselves stay in charge.

This post explains one method we're starting to use for this. I'm writing it to be transparent with projects, the wider community and potential funders about what we're starting to do. As well as to explicitly solicit feedback on this method.

Community work orders

If you talk to someone about supporting an open source project, in particular a well-known one that they rely on (e.g. NumPy, Jupyter, Pandas), they're often willing to listen and help. What you quickly learn though is that they want to know in some detail what will be done with the funds provided. This is true not only for companies, but also for individuals. In addition, companies will likely want a written agreement and some form of reporting about the progress of the work. To meet this need we came up with community work orders (CWOs) - agreements that outline what work will be done on a project (implementing new features, release management, improving documentation, etc.) and outlining a reporting mechanism. What makes a CWO different from a consulting contract? Key differences are:

  1. It must be work that is done on the open source project itself (and not e.g. on a plugin for it, or a customization for the client).
  2. The developers must have a reasonable amount of freedom to decide what to work on and what the technical approach will be, within the broad scope of the agreement.
  3. Deliverables cannot be guaranteed to end up in a project; instead the funder gets the promise of a best effort of implementation and working with the community.

Respecting community processes

Point 3 above is particularly important: we must respect how open source projects make decisions. If the project maintainers decide that they don't want to include a particular change or new feature, that's their decision to make. Any code change proposed as part of work on a CWO has to go through the same review process as any other change, and be accepted on its merits. The argument "but someone paid for this" isn't particularly strong, nor is one that reviewers should have to care about. Now of course we don't expect it to be common for work to be rejected. An important part of the Quansight value proposition is that because we understand how open source works and many of our developers are maintainers and contributors of the open source projects already, we propose work that the community already has interest in and we open the discussion about any major code change early to avoid issues.
