ABSTRACT
The model used in the development of this methodology is
a highly complex global, multicorporate, multiplatform,
intra-and Internetworked environment that substantiates
the need for a synergistic business approach for bridging
the gaps between the four key area product development
support functions: system design and development, con-
figuration management, information security, and quality
assurance. These systems encompass
some 3,600 personnel about 1,682 large mainframes, minis, and dispersed
cooperative systems
five types of operating systems a variety of network and communication protocols varying geographical locations
This approach forms an enterprise-wide discipline
needed for assuring the integrity, reliability, and continuity
of secure information products and services. Although the
development and maintenance concepts for high-integrity
systems are specifically addressed, the processes described
are equally applicable to all systems, regardless of size or
complexity.
