Some “Aerospace” Definitions
From Random House, Webster’s College Dictionary: aerospace – n. 1. the atmosphere and the space beyond considered as a
whole. aerospace – n. 2. the industry concerned with the design and manufacture
of the aircraft, missiles, spacecraft, etc., that operate in aerospace. From practice:
aerospace – n. 1. what we do today: Network Centric Solutions / Systems of Systems
Air Traffic Management Future Combat Systems Homeland Security National Missile Defense
Platforms – commercial aircraft, fighters, tankers, C4ISR, Bombers, helicopters, unmanned aircraft, missiles, satellites.
Enormous variety in each category

Some “Systems” Definitions
From Random House, Webster’s College Dictionary:
system – n. 1. an assemblage of things or parts forming a complex or unitary whole.
systems engineer – n. 1. an engineer who specializes in the design and implementation of production systems.
From practice:
system – n. 1. a collection of things working together to produce something greater.
2. a set of different elements so connected or related as to perform a function not performable by the elements alone.
systems engineering – n. 1. an interdisciplinary collaborative approach to derive, evolve, and verify a life cycle balanced system solution that satisfies customer expectations and meets public acceptability. Systems engineering is a generic problem solving process that provides the mechanisms for identifying and evolving the product and process definitions of a system.

Some “Architecture” Definitions
From Random House, Webster’s College Dictionary:
architect – n. 1. a person who engages in the profession of architecture.
architecture – n. 1. the profession of designing buildings, open areas, communities, and other artificial constructions and environments.
From practice:
architecture – n. the science (analysis-based, factual, logical and, deductive) and art (synthesis based, intuitive, judgmental, and, inductive) of designing complex systems that meet the user’s need in the physical and social environment.
“The ideal architect should be a man of letters, a skilled draftsman, a mathematician, familiar with historical studies, a diligent student of philosophy, acquainted with music; not ignorant of medicine, learned in the responses of jurisconsults, familiar with astronomy and astronomical calculations.” – Vitruvius, 25 B.C.

The Urgency for NCO Solutions
“… we must achieve: fundamentally joint, network-centric, distributed forces capable of rapid decision superiority and massed effects across the battlespace.”
Secretary of Defense Donald Rumsfeld
"In the future, we can realize tremendous leverage through a network by sharing information and capabilities by turning data into information, information into knowledge, knowledge into decision-making, and decision-making into action."
James Albaugh, 2004
“I don’t want to wait for an 80% solution. What I need is a 20% solution now that gives me a 5% advantage over the enemy!”
Col John Coleman, USMC (Chief of Staff, First Marine Expeditionary Force, Operation Iraqi Freedom)

What I’ve Learned – Scientia est Potentia
Emphasize knowledge of mathematics, science, and engineering; we’ll teach you the application specifics
Understand the “social” contract at work - Boeing example Understand the “social” contract away from work Read and develop in all three dimensions Develop your oral and written communication skills Never compromise on integrity issues
Work on what you believe in Work on what you find interesting Think about which career path you are interested in
Operate to a plan The underlying assumptions and the plan will change
Run to the fire When something goes wrong, blame yourself
