Question: 1 / 400

Which concept is based on the "zero-loss" principle?

KOV

DPMO

TPM

The concept that is based on the "zero-loss" principle is Total Productive Maintenance (TPM). This principle focuses on maximizing the operational efficiency of equipment by minimizing downtime and loss. TPM emphasizes proactive and preventative measures to ensure that machinery operates at peak performance, aiming for zero unplanned breakdowns, zero defects, and zero accidents. By doing so, the goal is to enhance productivity and overall equipment effectiveness.

In contrast, the other options present different focuses within quality and process improvement. KOV (Key Output Variables) pertains to the critical variables that impact a process's output quality and efficiency, rather than directly addressing equipment maintenance or loss. DPMO (Defects Per Million Opportunities) is a metric used in Six Sigma to quantify the number of defects in a process, and while it strives to minimize defects, it does not directly relate to the maintenance of equipment or the concept of "zero-loss." VOC (Voice of the Customer) involves understanding customer requirements and ensuring that processes align with those needs, which again does not pertain directly to minimizing equipment loss or downtime.
