J.D. Power and Associates
Power began conducting customer satisfaction research on April 1, 1968, as founder of the marketing information firm J.D. Power and Associates. Power started J.D. Power and Associates at the kitchen table with his family and initially the "Associates" in the firm's title were his own wife and children. The Power family also took out a second mortgage on their existing house at the time to support the fledgling company.

Power, David Power's wife, discovered a design flaw in certain Mazda automobiles, which was then publicized by The Wall Street Journal. In the following years, J. D.

He also stepped down as chairman but remained active with strategic planning.
