A factory adopted a sensor based maintenance system which started detecting machine faults early. Which dimension is this?

Correct answer: Technological dimension

Direct answer: Option C, the technological dimension. A sensor-based maintenance system uses sensors, monitoring equipment and data processing to detect machine faults early. These are applications of technology and innovation in production. The important clue is the sensor system, not merely the possible saving in repair cost. Option A, economic dimension, would be indicated by prices, wages, income, costs or interest rates; reduced losses may be a result, but it is not the main feature described. Option B, social dimension, concerns people, population and lifestyle, which are not the focus. Option C is correct because the change is the adoption of a technology that improves machine monitoring. Option D, political dimension, concerns government and policy, with no such factor mentioned. Memory cue: sensors, automation, digital monitoring and new machinery point to technology.
