In DMAIC, which phase collects baseline data on current processes and identifies problems?

• A. Define
• B. Measure
• C. Analyze
• D. Improve

Answer: (B)

The key idea here is gathering and quantifying how the current process actually performs. In the Measure phase, you collect baseline data on the process’s key metrics, establish the starting performance level, and check that your measurement methods are accurate and reproducible. This step reveals how big the problems are, how much variation exists, and where to focus improvement efforts. It also sets up the ability to compare future results after changes are made, and you often assess measurement system reliability and process capability at this stage. Defining the problem, scope, and goals happens before measuring in order to set direction. Analyzing uses the collected data to uncover root causes, rather than just collecting data itself. Improving focuses on designing and testing solutions to address those root causes.
