Abstract

The IETF has designed process changes over the last ten years in one of two ways: announcement by the IESG, sometimes based on informal agreements with limited community involvement and awareness, and formal use of the same mechanism used for protocol specification. The first mechanism has often proven to be too lightweight, the second too heavyweight. This document specifies a middle-ground approach to the system of making changes to IETF process, one that relies heavily on a "propose and carry out an experiment, evaluate the experiment, and then establish permanent procedures based on operational experience" model rather than those previously attempted.

1. Introduction

This document specifies a middle-ground approach to the system of making changes to IETF process, one that relies heavily on a "propose and carry out an experiment, evaluate the experiment, and then establish permanent procedures based on operational experience" model rather than those previously attempted.

2. Background and Specification

Since the 1992 changes documented in [RFC1396], the IETF has used two mechanisms for process changes. 1. IESG has adopted a number of procedural changes on its own initiative and documented them informally, utilizing the wide discretion implicitly granted to them by [RFC2026]. This provided a lightweight mechanism for change, but the lightness came with a cost: There was sometimes too little alignment with the larger IETF community. 2. The IETF has also used the [RFC2026] protocol standards development process to identify a community of interest, hold one or more BoFs, charter a working group, discuss proposed changes within the community, develop IETF-wide consensus on the changes, and publish (usually) Best Current Practice specifications. This provided full community involvement but also came with a cost in flexibility. The IETF does not change its formal processes often (the IPR clarifications in [RFC3667, RFC3668] are the first documented changes to [RFC2026] since 1996), and the community is understandably reluctant to permanently alter or extend formally adopted processes with untried new procedures. There is a middle ground between BCP process updates and informal agreements. This document specifies regularizing and formalizing the informal IESG mechanisms listed in 1 above as a means of moving forward with procedural changes that might prove valuable. The mechanisms outlined here add to the IESG's range of tools for dealing with process issues on an ongoing basis. They supplement the existing tools rather than attempting to replace them with a single "magic bullet". The choice of using the procedure outlined in this document or other mechanisms available to the IESG and the community -- present or future -- remains in the IESG's hands. If the IESG does not exercise this discretion wisely, this document provides no additional remedies.
Top   ToC   RFC3933 - Page 3
   Some have interpreted the current procedures as giving the IESG all
   of the capabilities outlined here.  If this were true, this document
   only encourages the IESG to use this type of mechanism more
   frequently in preference to less streamlined ones, and to more
   explicitly document its actions and decisions.

   This specification permits and encourages the IESG to adopt and
   institute "process experiments" by using the following procedure:

   1. An I-D is written describing the proposed new or altered
      procedure.  A statement of the problem expected to be resolved is
      desirable but not required (the intent is to keep the firm
      requirements for such an experiment as lightweight as possible).
      Similarly, specific experimental or evaluative criteria, although
      highly desirable, are not required -- for some of the process
      changes we anticipate, having the IESG reach a conclusion at the
      end of the sunset period that the community generally believes
      things to be better (or worse) will be both adequate and
      sufficient.  The I-D must state an explicit "sunset" timeout
      typically, not to exceed one year after adoption.

   2. If the IESG believes the proposal is plausible and plausibly
      useful, a four-week IETF Last Call is initiated.  The IESG can
      institute whatever procedures it wishes to make this determination
      and to avoid denial of service attacks from large numbers of
      spurious or unimportant proposals.  In particular, they might
      institute a procedure requiring a number of endorsements, or
      endorsements of a particular type, before the IESG considers the
      proposal.  The IESG is, however, expected to understand that
      procedures or review processes that act as a mechanism for
      significant delays do not fall within the intent of this
      specification.

   3. At the conclusion of the Last Call, the IESG reevaluates the
      plausibility and appropriateness of the proposal.  If they
      conclude that the proposed experiment is appropriate, a second I-D
      is generated (either by the IESG or by the original authors with
      IESG advice) that cleans up any definitional issues exposed in the
      Last Call and that explicitly identifies and responds to issues
      raised during the Last Call.

   4. The document and experiment are then announced, the experiment is
      begun, and the document is forwarded for publication as an
      Experimental RFC.
Top   ToC   RFC3933 - Page 4
   The IESG is explicitly authorized to use this mechanism (based on
   Experimental RFCs) to gain experience with proposed changes to BCP
   specifications.  There is no requirement to approve a BCP
   specification for the experiment until the experiment is found to
   have value.

   The IESG could, of course, reach a "bad idea" conclusion at any stage
   in this process and abandon the experiment.  It might recommend
   publication of the experimental document, with a discussion of why it
   was a bad idea, but is not required to do so.  The list above is
   deliberately vague about where the I-Ds come from: a WG, design team,
   individual contribution, editing group, or other mechanism could be
   used in the first and/or third steps, but no specific mechanisms are
   required, and the IESG is explicitly permitted to generate such
   proposals internally.

   In each case, the IESG's decision to go forward (or not) with a
   procedural experiment, or the steps leading up to one, is expected to
   reflect their judgment of the existence of rough consensus in the
   community.  That judgment may be appealed using the usual procedures,
   but the IESG and the community are reminded that an experimental
   attempt to try something for a fixed period is typically a better
   engineering approach than extended philosophical discussion without
   any experience to back it up.

   Nothing above is to be construed as requiring an IETF-wide attempt
   for any given process experiment.  A proposal for such an experiment
   may specify selected areas, selected working groups, working groups
   meeting some specific criteria (e.g., those created after a
   particular time or of a specified age), or be specific in other ways.

   At or before the end of the "sunset" timeout, the IESG would either
   revise (or cause to be revised) the document into a BCP RFC or the
   procedure would expire and, presumably, not be tried again unless
   something changed radically.  A document describing why the
   experiment had succeeded or failed would be desirable but could not,
   realistically, be a requirement.  If the procedure went to BCP, the
   BCP would reflect what we would call "operational experience" in the
   real world.

   We note that, if the procedures the IESG has adopted (and the
   procedural exceptions it has made) over the last decade are
   legitimate, then the IESG has the authority to institute the changes
   specified here by bootstrapping this process.

3. Security Considerations

This document specifies a mechanism for evolving IETF procedures. It does not raise or consider any protocol-specific security issues. In considering experimental changes to procedures, the IESG should, of course, exercise due caution that such changes not reduce the quality of security review and consideration for protocols or, at least, that the process experiment proposals contain early detection and correction mechanisms should quality deterioration occur.

4. Acknowledgements

The first revision of this document benefited significantly from suggestions and comments from Avri Doria, Margaret Wasserman, and Harald Alvestrand, and from discussions with the General Area Directorate and at its open meeting during IETF 59. After mailing list discussion, considerable explanatory material was removed to a separate document for the current version. The first version of this document was posted as an Internet Draft on February 7, 2004.
