Before We Share our Opinions…… 02 Sept 2015 4/22/2017 Before We Share our Opinions…… “At lectures, symposia, seminars, or educational courses, an individual presenting information on IEEE standards shall make it clear that his or her views should be considered the personal views of that individual rather than the formal position, explanation, or interpretation of the IEEE.” IEEE-SA Standards Board Operation Manual (subclause 5.9.3) 02 Sept 2015 2

The IEEE Standards Association process 02 Sept 2015 The IEEE Standards Association process 02 Sept 2015

IEEE-SA Individual and Corporate Standards Development 02 Sept 2015 IEEE-SA Individual and Corporate Standards Development Open, consensus process Individual standards development Each individual has one vote Corporate standards development One company/one vote Results frequently adopted by national, regional, and international standards bodies 02 Sept 2015

IEEE Standards Development: Process Flow 02 Sept 2015 IEEE Standards Development: Process Flow Idea! Project Approval Process Develop Draft Standard (in Working Group) Sponsor Ballot IEEE-SA Standards Board Approval Process Publish Standard Maximum of 4 years Revise or Withdraw Standards Maximum of 10 years Decide / Choose Technology Write / update a Draft Ballot Draft Resolve Comments Done? This chart illustrates the whole standards process in simplified form. Idea: The idea for a standard is usually developed by a group of people, and the responsibility for the idea is assumed by the sponsor. The sponsor is usually a society or an existing standards committee. Project Approval Process: This idea is then transferred onto a form called the Project Authorization Request (PAR) and submitted to the New Standards Committee (NesCom) for approval. Develop draft standard: The draft is then developed and revised by the working group. Ballot draft: When the draft work is finalized, the sponsor forms the balloting group and ballots the standard. Standards Board Approval: After your ballot has achieved consensus, the draft then goes to the Review Committee (RevCom) and the Standards Board for approval. The amount of time from PAR to Board approval is 4 years (an extension can be made if absolutely necessary). Publish Standard: The draft is then edited and formatted by an IEEE Project Editor and published. The standard is valid for 10 years before it must be revised or withdrawn. 02 Sept 2015 Jon Rosdahl, CSR Technologies Inc.

IEEE Standards Development: Project Authorization 02 Sept 2015 IEEE Standards Development: Project Authorization A project may be started by any individual or company Each project must be supported by a technical group in the IEEE Referred to as a “Sponsor” Official developer of standard Projects approved through document called Project Authorization Request (PAR) Summarizes details of project Approval of a PAR means that the work is authorized by the IEEE-SA Standards Board The PAR is the means by which IEEE can extend the umbrella of indemnification (or protection) to its standards developers 02 Sept 2015 Jon Rosdahl, CSR Technologies Inc.

IEEE Standards Development: Develop Draft Standard 02 Sept 2015 IEEE Standards Development: Develop Draft Standard Standard is written by working group Working group consists of developers interested in creating the standard Working group chooses way to create first draft document Group writes initial draft Draft developed from existing documents and specifications Draft document refined in working group through multiple iterations and review Some tips for starting the development of your draft include the following: • Develop an outline that will be used as key clauses. • Divide up each topic or clause among working group members, preferably according to their experience. • It is to your advantage to assign a working group member as a technical editor. During the development process, the technical editor will ensure consistency and can gather and incorporate all contributions and comments. • The working group meetings should only be used for reviewing important points in the draft and resolving areas of disagreement. • Working with an IEEE Project Editor will expedite the project since the editor can flag items that could otherwise be slowed down by the IEEE-SA Standards Board during the approval process. • Use the IEEE Standards Style Manual as the reference for document structure. 02 Sept 2015 Jon Rosdahl, CSR Technologies Inc.

IEEE Standards Development: Consensus process 02 Sept 2015 IEEE Standards Development: Consensus process Consensus is determined through a ballot Interested persons or organizations are invited to ballot on draft standards Ballot group receives document, reviews it, and votes/comments on it Vote yes (approve), no (disapprove), abstain Can offer comments on document as well Ultimate approval of standard is granted by IEEE-SA Standards Board • The sponsor forms the balloting group. In some cases, this may involve using the membership of an active committee or committees; in other cases, this may involve inviting a wide variety of interested parties to participate. • The sponsor also approves the balance of the group. No one interest group can be more than 33%. • Once the balloting group is formed, the composition of that balloting group cannot change until the close of the ballot. • The IEEE-SA now allows three types of ballot groups: one made up of individuals, one made up of Entities (persons who are representing an Entity), and one made up of both of these types of ballots. See the IEEE-SA Standards Board Operations Manual for details of these balloting processes. 02 Sept 2015 Jon Rosdahl, CSR Technologies Inc.

IEEE Standards Development: Publication & Maintenance 02 Sept 2015 IEEE Standards Development: Publication & Maintenance Standard published after approval Standard is valid for 10 years after approval After 10 years, must be revised or withdrawn Once your standard has been approved, it will receive a thorough, detailed edit from an IEEE Standards editor. The editor does not make any technical changes, thereby ensuring the technical integrity of the document. It is also the role to the editor to format the text in accordance with IEEE Standards Style. A draft copy is then provided to the committee for final review. Appropriate editorial corrections are then made and the standard is published. Complimentary copies are then issued to the working group and awards are given to the Chair of the working group in recognition of the work done. 02 Sept 2015 Jon Rosdahl, CSR Technologies Inc.
