The EIA 632 standard has been developed that describes the “processes for
engineering a system.” This standard evolved from EIA/IS 632—the interim standard that
describes a systems engineering process. This paper will describe the heritage of this
standard, reasons for this particular evolutionary step, and the approach in converting from
the interim standard to the full standard.
In April 1995, the G47 Systems Engineering Committee of the Electronic Industries
Association (EIA) chartered a working group to convert the interim standard EIA/IS 632 into
a full standard. This full standard has been developed over the last three years and is
planned for release in July 1998.
The interim standard, EIA/IS 632, was titled “Systems Engineering.” The full standard
was expanded in scope to include all the technical processes for engineering a system. It is
intended to be a higher level abstraction of the activities and tasks found in the IS version
plus those other technical activities and tasks deemed to be essential to the engineering of a
This paper describes development of this standard including a description of the major
issues involved, the development risks, and the general development approach. The
intended purpose is to give the reader of the standard some background in its development
and to help other standards activities in developing their own standard.
The relationship of EIA 632 to other standards like EIA 731, ISO 15288, ISO 12207 and
others is described in [Sheard et. al 1998]. There is a separate paper that gives an overview
of the contents of the standard [Martin 1998]. [...]
