step for the presence of one or more DOWNTIME wastes -correct answer-Waste Walk
If your problem statement focuses on VARIATION within a process/workflow, which
Evaluation Pathway should you choose? -correct answer-Defect/Risk pathways (Six Sigma-
oriented tools) because the goal is to reduce or eliminate variation
