3.  David Tucker is a Lean Six Sigma (L6S) Master Black Belt for Logistics, Materials,
& Supply Chain at United Space Alliance (USA), located at the Kennedy Space
Center in Florida. USA is the prime contractor to NASA responsible for the
Space Shuttle.
 Dave has over 20 years experience leading teams, mentoring employees,
solving problems, conducting training, and improving operations. He has led
more than forty Kaizen Events, completed nearly two dozen process simulation
modeling projects, conducted dozens of training sessions, facilitated over a
hundred Belts & Team Leaders, and assisted with the implementation of
numerous process improvements saving millions of dollars.
 Dave has an extensive background in numerous process improvement tools
utilized in Lean Six Sigma DMAIC & DMEDI approaches, as well as Kaizen team
methods and process simulation modeling. He has over 9 years experience
using ProModel process simulation modeling tools for process improvement.
In addition, he is a sought after speaker and has made many well-received
presentations at Process Improvement, Simulation, and Aerospace Conferences.
He has a BSBA in Management from the University of Central Florida. Dave is a
Certified Lean Six Sigma Black Belt and a Certified Master Black Belt.
