Definition: Feasibility studies (S&T)
Feasibility studies are investigation of proposed engineering projects using existing techniques in order to provide additional information before deciding on implementation. In the social sciences, feasibility studies are investigations of the socio-economic characteristics and implications of specific situations (e.g. a study of the viability of a petrochemical complex in a certain region). However, feasibility studies on research projects are part of R&D. Feasibility studies should be excluded from R&D except where carried out solely or primarily for the purposes of an R&D project.
