Requirements Development: An Architectural Approach
A.M. - 4:30 P.M.
tutorial will discuss three ways to characterize a system:
(a) models, (b) requirements, and (c) design. We will show
how a system architecture serves to integrate these three
aspects of the system. This leads to a more model-driven systems
approach and allows you to “discover” the essential
attributes of the problem space that must be addressed by
the system solution. The architecture models are where these
essential attributes are defined and evaluated. The architecture
also provides the unifying framework for exploration of the
problem space and for characterization of the solution space
such that better decisions can be made. This tutorial will
describe an approach for the flowdown from the system purpose
or mission need, down through operational requirements and
concept of operations, and finally into system and lower-level
specifications. How and when to model different aspects of
the system will be discussed. We will also talk about the
benefits and limitations of modeling and simulation. Another
important topic to be covered is system threads and scenarios.
In addition to the basic flowdown of requirements, we will
show how the Zachman Framework and the C4ISR Architecture
Framework can be used to structure the development of complex
systems. A document tree template is described to assist a
project in the generation of the technical documentation necessary
for the organized development of systems.
Martin and Steve Heidorn,
The Aerospace Corporation
James N. Martin is an internationally known writer and lecturer
on systems engineering. He wrote one of the most widely read
books on systems engineering, Systems Engineering Guidebook,
published by CRC Press. His experience includes eighteen years
in systems development of telecommunications products and
services (most of this with Bell Labs) as program manager,
systems engineering manager, system architect, requirements
manager, and lead systems engineer. His experience with technology
includes mobile wireless, underwater fiber optic, satellite
broadband wireless, reconnaissance sensors and distribution
networks, and airborne network hubs.
At the Aerospace Corporation, Mr. Martin is a system architect
for communications networks and space systems. He also teaches
at The Aerospace Institute and at seminars around the world.
He led the development of ANSI/EIA 632, the US national standard
that defines the processes for engineering a system. Mr. Martin
graduated with an MS from Stanford and a BS from Texas A&M.
He is an INCOSE Fellow.
Steven Heidorn is a highly accomplished systems engineer
with nineteen years’ experience across a wide range
of defense, intelligence and commercial systems. As a lead
systems engineer, development engineering manager and chief
engineer at IBM Federal Systems, he developed real-time,
software-intensive, radar and sonar signal processing systems.
At the MITRE Corporation, he developed concepts for software-reconfigurable
sensor and communications processing systems and contributed
to the architecture of the Joint Tactical Radio System.
At the Aerospace Corporation, he provides system engineering
and system architecting expertise across a wide range of
information-intensive commercial, civil and intelligence
systems and also teaches at The Aerospace Institute. Mr.
Heidorn holds BS and MS degrees in electrical engineering
from the University of Illinois at Urbana-Champaign and
has done additional postgraduate work in statistical communication
theory at George Mason University.
