|Process technology¬†has been defined by the United States¬†Food and Drug Administration¬†(FDA) as a mechanism to design, analyze, and control pharmaceutical manufacturing processes through the measurement of¬†Critical Process Parameters¬†(CPP) which affect¬†Critical Quality Attributes¬†(CQA). The impact factor of Process technology journals provide quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
