PROFESSIONAL EXPERIENCE
Since
2004, Dr. Locke, President of Locke Consulting LLC., has been a full-time
consultant with a variety of clients involved primarily in Military, Aerospace,
Industrial Control, and Telecommunications systems. His extensive technical
and business background in areas such as software engineering, software performance,
real-time architecture, design, implementation, and deployment, international standards,
software engineering maturity, and software development management and organization
has made a major impact on organizations creating complex systems. He has used
and analyzed more than 25 computer languages, including Java, C, C++, Python,
HTML, JavaScript, as well as a variety of computer assembly languages. His
clients include over 40 companies and agencies, including the Naval Systems
Warfare Center, DoD Office of the Secretary of Defense, Raytheon Corporation,
Jet Propulsion Laboratory, Baxter International, Motorola (now Google), and Sun
Microsystems (now Oracle).
From
2016 to 2021, he served as a Visiting Professor at Davidson College, Davidson,
North Carolina in the Department of Mathematics and Computer Science. In this capacity, he developed and/or taught courses including Programming and Problem Solving, Software Engineering, Data
Structures, and Computer Architecture & Organization. Previously he also served as an Adjunct
Professor at Lenoir-Rhine University in Hickory, North Carolina where, in the
department of Mathematics and Computer Science, he taught a class on C++.
In
addition to his work with clients involved in specifying, building, and
deploying software-intensive systems, including embedded and real-time systems,
he also has experience serving as an Expert (including expert reports,
depositions and courtroom testimony) in intellectual property-related
litigation including patents, copyrights, trade secrets, and contracts. Recent
cases involve patents for computer controls for heavy-duty truck transmissions,
patents for safety/control systems for hospital proton beam therapy systems, smartphones,
and trade secrets associated with vehicle tracking devices.
Prior
to February 2004, Doug served as the Vice President of Technology for TimeSys
Corporation, a producer of Embedded Linux distributions and software
development tools. In this position, he had responsibility for defining
the technology base for the corporation and extending it to meet customer
requirements. While at TimeSys, he also served as a key consultant and
instructor for TimeSys critical projects and classes, provided key customers
with systems and software consultation, and provided an external presence for
the corporation in the embedded systems community with frequent
publications and public presentations.
Prior
to January 2000, Dr. Locke served as the Chief Scientist of the Lockheed Martin
Systems Solutions organization. His responsibilities there were to define
the software and systems technology focus for a new business thrust involving
efforts by major industries worldwide transitioning from mainframe-based,
"stovepipe" application architectures to distributed architectures. Most
of the customers for this formerly exclusively aerospace organization required
exploitation of the same kind of real-time, limited footprint, embedded systems
experience for which Lockheed Martin is well-known. In addition to his
work with major commercial customers, he also consulted extensively with other
major Lockheed Martin projects across the corporation.
From
September, 1989 to August, 1998, he was the Chief Scientist of IBM's (and Lockheed
Martin's after IBM's FSD was acquired by Lockheed Martin) Software &
Systems Resource Center. His responsibilities there centered primarily on
management, systems, and software consulting across IBM and Lockheed Martin,
guiding major projects' management as well as the technology dissemination
activities at the SSRC, reviewing / updating the SSRC's educational offerings,
and leading / participating in major program reviews / audits. A wide
variety of projects were supported such as the Space-Based Infrared System (SBIRS),
Sustaining Base Information System (SBIS), Air Traffic Management, GPS, various
avionics systems, Close Combat Tactical Trainer (CCTT), Light Airborne
Multipurpose System (LAMPS), and Airborne Warning and Control System
(AWACS)
.
At
IBM and Lockheed Martin, Dr. Locke led and participated in many management and
technical review teams evaluating major government projects with respect to
their ability to successfully manage and complete complex system development
and deployment. At TimeSys Corporation,
where Dr. Locke served as VP Technology and VP Engineering, he had an active
role in all aspects of the corporate leadership, including CEO recruitment, venture
capital interfaces, marketing, sales, technology, engineering, and customer
satisfaction.
From
1981 through 1999, Dr. Locke acted as a consultant to all levels of management,
senior technical staff, and customers for a wide variety of Lockheed Martin,
Loral, IBM, TimeSys, and other system development, research, product
development, and standards activities. This consultation covered both
management and technical issues related to real‑time software
development, open systems, object-oriented systems, Ada, C, C++, and Java
applications, and general systems performance. Projects on which he has spent
substantial amounts of time include the Air Force's Theater Battle Management
Core System, the Global Positioning System, Air Traffic Control, the UK
Ministry of Defense Merlin System (an Anti‑Submarine Warfare helicopter),
the Navy's LAMPS ASW helicopter system, the Army's Rotorcraft Pilot's
Associate, the Army's Sustaining Base Information System, and the Joint
Tactical Radio System.
Throughout
his consulting work, he frequently led and participated in major project audits
and reviews, especially for major proposals, projects experiencing
cost/schedule perturbations, and projects experiencing performance
difficulties.
In
addition to his other ongoing responsibilities, Dr. Locke has led and/or
participated in a number of international standards including the Portable
Operating System Interface (POSIX) standard (IEC/ISO 9945, the Real-Time Common
Object Request Broker Architecture (CORBA) by the Object Management Group, the
Real-Time Specification for Java (RTSJ JSR-1) under the Java Community Process,
and the Safety Critical Java (SCJ JSR-302) also under the Java Community
Process.
Between
1992 and 1995, he served as a regular instructor for the U.S. Air Force's Operation
Bold-Stroke, teaching software procurement and management principles to
senior officers (Generals, Colonels, and equivalent civilian staff only.)
