Research and development (R and D) is the search for new and improved products and industrial
processes. Both industrial firms and governments carry out Rand D. Innovations in products or
processes normally follow a path from laboratory (lab) idea, through pilot or prototype
production and manufacturing start-up, to full-scale production and market introduction. There
are two main types of research. Pure or basic research aims to clarify scientific principies without
a specific end product in view; applied research uses the findings of pure research in order to
achieve a particular commercial objective. Development describes the improvement of a product
or process by scientists in conjunction with engineers. Industry spends vast sums to develop new
products and the means to produce them cheaply, efficiently, and safely
