ISO/IEC 12207 Updated and Renumbered as ISO/IEC/IEEE 12207

ISO/IEC 12207 has been updated.  Along with the technical updates, the document has been issued under a new publication number, ISO/IEC/IEEE 12207.  This new 1st Edition replaces the old number’s 2008 2nd Edition.  The title remains the same, Systems and software engineering – Software life cycle processes.

Confusion over the document’s number is understandable.  This is a standard that originated at IEEE when it was first released.  Over the years, it has moved to the jurisdiction of ISO/IEC’s Joint Technical Committee 1 (JTC1) in cooperation with IEEE.  So both ISO/IEC and IEEE have released this new document at the same time.  To differentiate the 2 separate editions (as well as price correctly and meet our contractual obligations to each organization), we have the item in our system multiple times.  However, each entry is a bit different.

You’ll find the international edition as ISO/IEC/IEEE 12207, in both paper format and for pdf download.  The IEEE edition is available in paper format as IEEE/ISO/IEC 12207.  It is available for pdf download as IEEE/ISO/IEC 12207-P.  The document is also available as part of our Standards Online cloud enterprise solution.  The standard is identical no matter how you get it.  However, the prices will vary.

Why a new edition for the ISO/IEC/IEEE 12207?  The document needed to be harmonized with the ISO/IEC/IEEE 15288 from 2015.  Areas that were creating difficulties were the variations in terminology and the process structure of each.  So this new edition provides a pathway towards a harmonized future, but not forgetting backward compatibility.  It is a technical update and replaces all previous editions.
