Standardization process A standard published by ISO/IEC is the last stage of a long process that commonly starts with the proposal of new work within a committee. Here are some abbreviations used for marking a standard with its status:<ref name="about-mpeg">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name="iso-stages-codes">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name="iso-stages">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name="acronyms-committees">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name="iso-directives-procedures">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name="abbr">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name="us-tag-committee">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

International Standards are developed by ISO technical committees (TC) and subcommittees (SC) by a process with six steps:<ref name="iso-stages"/><ref name="iso-directives-part1">{{#invoke:citation/CS1|citation |CitationClass=citation }}</ref>

  • Stage 1: Proposal stage
  • Stage 2: Preparatory stage
  • Stage 3: Committee stage
  • Stage 4: Enquiry stage
  • Stage 5: Approval stage
  • Stage 6: Publication stage

The TC/SC may set up working groups (WG) of experts for the preparation of a working drafts. Subcommittees may have several working groups, which can have several Sub Groups (SG).<ref name="wg11-structure">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

It is possible to omit certain stages, if there is a document with a certain degree of maturity at the start of a standardization project, for example a standard developed by another organization. ISO/IEC directives allow also the so-called "Fast-track procedure". In this procedure a document is submitted directly for approval as a draft International Standard (DIS) to the ISO member bodies or as a final draft International Standard (FDIS) if the document was developed by an international standardizing body recognized by the ISO Council.<ref name="iso-stages"/>

The first step—a proposal of work (New Proposal) is approved at the relevant subcommittee or technical committee (e.g., SC29 and JTC1 respectively in the case of Moving Picture Experts Group - ISO/IEC JTC1/SC29/WG11). A working group (WG) of experts is set up by the TC/SC for the preparation of a working draft. When the scope of a new work is sufficiently clarified, some of the working groups (e.g., MPEG) usually make open request for proposals—known as a "call for proposals". The first document that is produced for example for audio and video coding standards is called a verification model (VM) (previously also called a "simulation and test model"). When a sufficient confidence in the stability of the standard under development is reached, a working draft (WD) is produced. This is in the form of a standard but is kept internal to working group for revision. When a working draft is sufficiently solid and the working group is satisfied that it has developed the best technical solution to the problem being addressed, it becomes committee draft (CD). If it is required, it is then sent to the P-members of the TC/SC (national bodies) for ballot.

The CD becomes final committee draft (FCD) if the number of positive votes is above the quorum. Successive committee drafts may be considered until consensus is reached on the technical content. When it is reached, the text is finalized for submission as a draft International Standard (DIS). The text is then submitted to national bodies for voting and comment within a period of five months. It is approved for submission as a final draft International Standard (FDIS) if a two-thirds majority of the P-members of the TC/SC are in favour and not more than one-quarter of the total number of votes cast are negative. ISO will then hold a ballot with National Bodies where no technical changes are allowed (yes/no ballot), within a period of two months. It is approved as an International Standard (IS) if a two-thirds majority of the P-members of the TC/SC is in favour and not more than one-quarter of the total number of votes cast are negative. After approval, only minor editorial changes are introduced into the final text. The final text is sent to the ISO Central Secretariat, which publishes it as the International Standard.<ref name="about-mpeg"/><ref name="iso-stages"/>
