Stage 3Stage 3
Streamline all activities. Analyze the elements (facts), and
discuss all possible ways of improving the step.
Study the external activities as well as the internal activities.
Common issues: • Fastenings – Are bolts needed? If so
remember that only the last turn tightens a nut or bolt.
• Standardize die heights.
