Team of specialists
A tiger team is a team of specialists assembled to work on a specific goal, or to solve a particular problem.
Origin of the term.
A 1964 paper entitled "Program Management in Design and Development" used the term "tiger teams" and defined it as "a team of undomesticated and uninhibited technical specialists, selected for their experience, energy, and imagination, and assigned to track down relentlessly every possible source of failure in a spacecraft subsystem or simulation". Walter C. Williams gave this definition in response to the question "How best can advancements in reliability/maintainability state-of-the-art be attained and used with compressed schedules?" Williams was an engineer at the Manned Spacecraft Center and part of the Edwards Air Force Base National Advisory Committee for Aeronautics. 
The paper consists of anecdotes and answers to questions from a panel on improving issues in program management concerning testing and quality assurance in aerospace vehicle development and production. The panel consisted of Williams, Col. J. R. Dempsey of General Dynamics, Lt. Gen. W. A. Davis from the Ballistic Systems Div., Norton Air Force Base, A. S. Crossfield from North American Aviation.
