This Standard is intended to enable an organization to improve its capability to engineer and produce quality product, and deliver them on time at an affordable price or cost. this Standard EIA731, is intened to be the Standard for Systems Engineering Capability. As such, it complements the usage of the EIA632, Processes for Engineering a System, and IEEE Standard 1220-1994, IEEE Trial-Use Standard for Application and Management of the Systems Engineering Process. Those standards define the "what-to-do's" of the processes for engineering systems, and this model provides a basis for determining "how well" those processes are defined and implemented. This Standard is intended to provide complete coverage of the EIA632 and be consistent with both it and IEEE 1220-1004.
