|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). Process Technology Review articles are the summary of current state of understanding on a related research topic. They analyze or discuss research previously published by scientist and academicians rather than reporting novel research results in the field of Chemical engineering.
Process Technology Review article comes in the form of systematic reviews and literature reviews and are a form of secondary literature. Systematic reviews determine an objective list of criteria, and find all previously published original research papers that meet the criteria. They then compare the results presented in these papers. Literature reviews, by contrast, provide a summary of what the authors believe are the best and most relevant prior publications.
The concept of ""review article"" is separate from the concept of peer-reviewed literature. It is possible for a review to be peer-reviewed, and it is possible for a review to be non-peer-reviewed.
