In essence, TA could be defined as "a form of policy research that examines short- and long term consequences (for example, societal, economic, ethical, legal) of the application of technology.
Technology assessment was initially practiced in the 1960s in the United States where it would focus on analyzing the significance of "supersonic transportation, pollution of the environment and ethics of genetic screening.
"[3] Also, technology assessment recognizes the fact that scientists normally are not trained ethicists themselves and accordingly ought to be very careful when passing ethical judgement on their own, or their colleagues, new findings, projects, or work in progress.
TA considers its task as an interdisciplinary approach to solving already existing problems and preventing potential damage caused by the uncritical application and the commercialization of new technologies.
It handles the assessment of effects, consequences, and risks of a technology, but also is a forecasting function looking into the projection of opportunities and skill development as an input into strategic planning.
