PowerShell RFC Process and Guidelines

A PowerShell RFC (Request for Comments) is a publication to propose design changes and improvements to PowerShell. This provides the community an opportunity to provide feedback before code is written where it becomes harder to change at the risk of compatibility. The complete list of RFCs are available at

This process was adapted from the Chef RFC process as well as from the process.


  • Author: All members of the community are allowed to author new RFCs and can provide feedback to any RFC.
  • PowerShell Committee: The design committe that votes to accept or reject an RFC. (Learn more about the PowerShell Committee here.)
  • Committee Member: An individual member of the PowerShell Committee.

RFC Submission Convention

  • When submitted, RFC documents shall follow the naming convention of RFCNNNN-<Title>.md.
  • Authors of RFCs shall not assign the RFC number (leave the NNNN in the filename).
  • When the Pull Request is submitted, the author shall check Allow edits from maintainers so that the Committee can add the RFC number to the draft, update the title, and fix the filename.

RFC Template

All RFC documents shall follow the RFC template.

RFC Workflow

RFCs may go through the following stages:


This is the initial draft of an RFC posted for comments and considered a work-in-progress.

  • New proposed drafts should be submitted as a Pull Request from the Author's fork into the Draft-Accepted folder.
  • The Author shall ensure that the Allow edits from maintainers box is checked so that a Committee Member can assign the next RFC number.
  • If the Pull Request has followed the correct template and process, a Committee Member will assign the label Review - Open for comments to the Pull Request to indicate that anyone can comment on the content of the submission. Typically, one or two months is allowed for comments, though this may be extended if a submission is particularly contentious or hasn't received enough feedback for the Committee to feel comfortable making a decision.
  • When the Committee closes the comment period, the Author should update the RFC and Pull Request with a new commit to address the comments.
  • The Committee shall vote to merge or reject the RFC. Note: the Committee may be slower to respond to RFCs where the Author has indicated that they do not plan to implement the RFC.


The PowerShell Committee has reviewed the RFC and comments, and has voted to accept the RFC as a Draft.

  • New comments are not being sought.
  • No one has begun implementing the RFC, and there are no current plans to implement the RFC. In this case, the Committee will create up-for-grabs Issues in the PowerShell repository.


RFCs in the Experimental stage have been accepted by the Committee, and code is being written to provide a working example of the proposed design change to get additional feedback.


Feedback from the experimental implementation and RFC have been reviewed.

Because this working prototype already exists in preview builds available on GitHub, the community provide feedback on the implementation as issues in the PowerShell/PowerShell repository

As the engineering team or code contributor works towards a final implementation, they should submit pull requests to PowerShell-RFC in order to keep the RFC in sync with the implementation. These pull requests shall be reviewed and accepted by the Committee, but a formal vote is not necessary. The Committee should merely confirm that the changes in the RFC match the working implementation.


RFCs in the Rejected state were rejected by the Committee who decided not to proceed further.


RFCs in the Withdrawn state were rescinded by the RFC Author.


RFCs in the Final state are considered fully complete and implemented in PowerShell. Any proposed changes should be made through a new RFC or via an Issue in the PowerShell/PowerShell repository. New RFCs should reference old RFCs where applicable.


v1.1 - 5-20-2016 - Updated to enable RFCs for design changes that don't require code changes. Added Draft-Accepted state and Version header property.

v1.2 - 8-18-2016 - Open submitting RFCs to the community and update formatting.

v1.3 - 9-26-2016 - Added Withdrawn stage. Comments Due field to template. Updated guidance on RFC numbering.

v1.3.1 - 3-22-2017 - Cleaned up language and made explicit clarifications to process

v1.4 - 3-31-2017 - Revised the RFC process to leverage pull requests for comments instead of issues. Continued cleanup of language and formatting.

You can’t perform that action at this time.
