Role and Technical Knowledge

1. 1

   What is the difference between a process and a method in manufacturing?

   A process is a sequence of steps to convert input to output, while a method is the specific way a step is performed. Give an example from assembly or machining.

2. 2

   How would you calculate the takt time for an assembly line?

   Takt time = available production time per shift divided by customer demand per shift. Explain how it helps balance the line.

3. 3

   What is the significance of Cp and Cpk in process control?

   Cp measures potential capability, Cpk measures actual capability considering centering. Higher values indicate a more capable process.

4. 4

   Explain the 8D problem-solving methodology.

   List the eight disciplines from team formation to closure, and mention that it is used for root cause analysis and corrective actions.

Practical Scenarios

1. 5

   You notice a recurring defect on the shop floor. How would you approach solving it?

   Use a structured method like DMAIC or 8D: define the problem, measure data, analyse root cause, implement and verify solutions.

2. 6

   How would you reduce cycle time on an existing production line?

   Conduct time studies, identify bottlenecks, eliminate non-value-added activities, and apply line balancing or automation where feasible.

3. 7

   A machine is consistently producing parts outside tolerance. What steps would you take?

   Check machine settings, tool wear, and raw material; use SPC charts to identify trends, then adjust or repair as needed.

4. 8

   How would you implement 5S in a workstation that is disorganized?

   Explain the five steps: sort, set in order, shine, standardize, and sustain. Emphasize employee involvement and audits.
