D & R Technical Solutions
D & R specializes in the area of Product Support, which means they assist companies in the development and fielding of their products, and help ensure those products are supportable by their customers after the sale is complete and the equipment is operational.
Product support is a niche but very diverse field, with many different elements and specialty areas. They specialize in four of those areas:
Technical Manual Development
Training Material Development
Product Support Analysis
3D Animations and Simulations
They do this for commercial and defense industries, for products large (railcars, vehicles, aircraft), medium (communications systems, battlefield command centers, airport runway lighting systems), and small (radar systems, fuel pumps, batteries).
