Since the second half of the 20th century, in practically every sector of the economy, Information Technology (IT) has been a significant agent of change. National Metrology Institutes (NMIs) have a long history of ensuring the accuracy of measurement data, and they are currently attempting with IT capabilities by digitizing these processes. This study contributes to that goal by discussing some new fields in IT that contributes to developing the new metrology world. This study reviews IT capabilities and activities in measurement and testing, as well as identifies key terminology and concepts in IT metrology. Then, we conclude what is expected to happen in the field of metrology over the next 10 years according to the impact of IT. On the other side, you will find in this research the role of metrology in developing IT. The NMIs and the scientific measurement community have faced particular technological hurdles in building a solid measuring and testing infrastructure for IT due to the complexity and continuously changing nature of IT. This infrastructure for measuring and testing essential non-physical and non-chemical features associated with sophisticated IT systems is still in its infancy. Therefore, in this paper, the current challenges to developing IT system-based metrology concepts have been discussed.
