Split the class into two groups.
You and your team are assembly-line workers in Company XYZ. Your line manager has given you a new product to assemble. You will assemble the product according to the manager’s instructions. Then you will brainstorm ways to improve the overall production.
The product is a bolt with three washers and a nut that holds the washers firmly in place. The diagram shows how the product should be assembled and what the finished product looks like.
Task 1: Place small washer on bolt and pass to position 2.
Task 2: Place large washer on bolt and pass to position 3.
Task 3: Place lock washer on bolt and pass to position 4.
Task 4: Tighten washers onto bolt with a nut.
Task 5: Check the quality of each product. Any piece that does not meet the standards shown in the illustration should be sent to position 6.
Task 6: Rework any defective products to bring them up to acceptable standards.
Task 7: Oversee the line production to make sure the assembly process runs smoothly.
Task 8: Supply each position on the line with needed parts.
Time how long it takes you.

Worksheet: New Trends in Manufacturing”
Winning team will be determined by time. A 5 second penalty will be given for each defective part (dropped or laying out not used) and a 25 second penalty for any defective bolt object (rattles or assembled in wrong order).
Teams will have 10 minutes to form their quality circles to discuss ways to improve production.
You do not have to assign duties the same as use in the previous assembly lines. More than one student may now do the same job, or simpler jobs may be combined as one job. Students will not be allowed to help others with their job or to switch jobs after the competition begins.
Team leader will give the instructor a list of student names and their duties.
The Assembly Line Challenge, Lesson 3
Quality control can be expressed as a rate that tells what portion of the “bolt objects” that were made passed inspection.
Production rate is the number of quality “bolt objects” produced per minute.(total made per minute).
