The predictive maintenance market is undergoing significant transformation, driven by technological innovations and major strategic movements. Two recent developments dominate the landscape: the emergence of a sound diagnostic technology for vehicles, dubbed the "Shazam" for cars, and the strategic acquisition of WeMaintain by Otis to strengthen predictive maintenance in the elevator sector. These developments illustrate a growing trend towards the integration of the Internet of Things (IoT) and artificial intelligence (AI) into maintenance systems, promising to enhance operational efficiency and reduce costs.
