Public communication takes place in the specs GitHub repository and the SPECs discussion forum. Private communication within the Steering Committee takes place on Steering Committee private mailing list. Steering Committee members are expected to be aware of conversations on this list to lend validity to consensus-seeking and voting.

How are SPECs accepted?#

To accept a SPEC (i.e., assigning it a SPEC number, marking its discussion Accepted, and merging the pull request) requires two members of the Steering Committee to approve and no members objecting. Since the role of the Steering Committee is mainly to ensure that SPEC proposals are appropriate,1 objections should be rare.

How is the SPEC process changed?#

The Steering Committee makes decisions about changing the SPEC process documents (SPEC Purpose and Process, SPEC Steering Committee, and SPEC Core Projects) through group consensus and, in the very rare instance where no consensus can be reached, by two-thirds majority vote of those available to cast a vote within ten days.

Who should be a member?#

Members of the Steering Committee should be active in the scientific Python ecosystem and should have a demonstrated interest in the Core Projects and the SPEC process. Examples of demonstrated interest include submitting SPECs, engaging in SPEC discussions, reviewing SPEC pull requests, or advocating for wider SPEC participation. Members of the steering committee do not have to belong to a core project.

How many members should there be?#

This is up to the Steering Committee. However, if the Steering Committee is unable to quickly handle new SPEC proposals and new ideas arising in the discussions aren’t addressed in a timely manner, the Steering Committee should try to recruit new members.

How do you add a member?#

If the Steering Committee decides to admit a new member and that person agrees, then they should be added to the (1) the Steering Committee member listing above, (2) the Steering Committee Team, and (3) the Steering Committee Discourse Group.

How do you remove a member?#

If a member wishes to resign or if the Steering Committee decides to remove a member, then they should (1) be moved to the list of Emeritus Steering Committee members (below the list of active members), (2) be removed from the Steering Committee Team, and (3) be removed from the Steering Committee Discourse Group.


  1. Proposed SPECs are accepted once (a) the draft is written to clearly explain the area of common concern and a general approach to a shared solution and (b) there are contributors (from at least two Core Projects) interested in working on the new SPEC and in championing it to their projects as well as the larger community. ↩︎
