Smart Metrology is a modern approach to industrial metrology. The name was introduced by Jean-Michel Pou and Laurent Leblond, a French meteorologist and a French statistician. The term was coined in their book, La Smart Metrology: De la métrologie des instruments à la métrologie des décisions. ^[1] It was then adopted by Deltamu, a French company providing services in the field of industrial metrology.

The approach promoted by Smart Metrology applies the exploitation of data and information, including that provided by big data, ^[2] to implement an approach based on the three pillars of metrology ^[3] ( uncertainty, ^[4] calibration and traceability) in industrial applications. ^[5]

The approach suggested by Smart Metrology is fully framed within the ISO 9001 recommendations. Usual metrology is often regarded as a pure cost and is actually not following the ISO 9001 quality standards.

Smart Metrology ^[1] follows a different approach according to the following steps:

• The measuring equipment is monitored using historical and relevant data to detect whether a doubt exists. If such a doubt exists, the equipment is calibrated.
• The available ( a priori) information is used by applying advanced statistical approaches, such as Bayesian inference, for monitoring and is used in the decision-making process. ^{[6] [7]}
• The calibration intervals were not at fixed intervals.

• Dimensional metrology
• Forensic metrology
• Time metrology
• Quantum metrology
