Industrial Maintenance Mechatronics Practice Test 2026 – Complete Exam Prep

In DMAIC, the phase that handles data collection and quantifying how the process currently performs is the Measure phase. It involves designing the measurement plan, selecting metrics (such as defect rate, cycle time, throughput, or yield), collecting data from the process, and establishing a baseline. It also checks the measurement system to ensure data quality, so the numbers you work with truly reflect current performance. This numeric baseline is what guides later analysis and improvement efforts.

The Define phase sets up the project and identifies what needs to be improved, including the problem statement and customer requirements. The Analyze phase uses the collected data to uncover root causes and verify patterns. The Improve phase develops and tests solutions to address the identified causes.
