In my opinion these are all legitimate criticisms. As I analyzed recent citation data for Optical Engineering papers to understand what factors drive impactful papers, it was apparent to me that the data were not well behaved, making simple statistical measures potentially misleading. Especially for an engineering-oriented journal such as ours, I question the inherent assumption that citations appropriately measure the scientific, commercial, or intellectual impact of journal papers. Analytical and experimental methods are often adopted from published papers and put into practice by engineers whose output is not journal publications but ultimately a new design, test methodology, production process, or other engineering product. This type of impact is extremely important for Optical Engineering, addressing a core industry-oriented constituency of SPIE. Impacts such as these are not at all captured by the impact factor metric.
