Reference excerpt

John Joseph Garstka (born February 20, 1961) is the acting CISO for acquisition and sustainment at the Department of Defense

Biography Garstka is a recognized international speaker and has delivered the Network Centric Warfare message to military and commercial audiences worldwide. In addition, he has lectured at Harvard University, Georgetown University, the University of California at Irvine, University of Maryland, the Army War College, the Air War College, the Naval War College, and the Naval Postgraduate School. Prior to joining the Office of Force Transformation, Garstka was the Chief Technology Officer in the Joint Staff Directorate for Command, Control, Computer and Communications (C4) Systems. In this capacity, he played a key role in the development and conceptualization of network-centric warfare and was the Joint Staff lead for the Department of Defense's Report to Congress on Network Centric Warfare. Prior to joining the Joint Staff, Garstka was a Senior Systems Engineer with Cambridge Research Associates, where he had responsibility for leading consulting engagements with commercial and government customers. Before joining Cambridge, Garstka served as an officer in the United States Air Force (USAF) for ten years, with assignments on the Air Staff and at USAF Space and Missile Center.

Early life and education Garstka was born in Tokyo and raised in Los Angeles. He graduated from Westchester High School in 1979. Garstka is a Distinguished Graduate of the United States Air Force Academy, where he earned a Bachelor of Science degree in Mathematics in 1983. He also holds a Master of Science Degree in Engineering-Economic Systems from Stanford University, where he studied as a Hertz Fellow.

Publications Publications and reports he has authored or co-authored include:

Network Centric Warfare: Developing and Leveraging Information Superiority, by Alberts, Garstka, and Stein, CCRP Press, 1999. This book has been reprinted by leading IT companies and translated into three languages. Online at the DoD Command and Control Research Program Understanding Information Age Warfare, by Alberts, Garstka, Hayes, and Signori, CCRP Press, 2001. Online at the DoD Command and Control Research Program Network Centric Warfare: Its Origin and Future, which appeared in Proceedings of the Naval Institute in January 1998.

Worked examples

Example 1 — a first encounter with John J. Garstka

Start with the simplest possible case. Write down what John J. Garstka claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to John J. Garstka before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about John J. Garstka ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of John J. Garstka

In research: John J. Garstka appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses John J. Garstka in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: John J. Garstka is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1961 births, Living people, Military personnel from Los Angeles, so understanding it makes those chapters shorter.
In everyday life: Look for John J. Garstka outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
