Implementation science has developed rapidly and has established frameworks for summarizing a variety of influences on intended outcomes. The frameworks are useful for guiding the work of implementation in typical human service practice settings and for generating useful hypotheses for social sciences to explore. Evaluations of successful efforts to make full and effective use of social science innovations to benefit citizens and society have led to rapid expansion of implementation science.
