  • 1. Lean Manufacturing Exam<br />NAME: _______________________________________<br />EXAM DATE: ______/______/______<br />For the following multiple choice questions, please indicate the best answer. Some answers may be correct but incomplete and not the best answer. Every correct response will earn the examine a point. Question 6, 8, 11, 13, 15, 16, 24, 27, 29, 30 and 31 are worth multiple points for correct responses. A calculator might be required.<br />
    • Value Stream Mapping looks at:
    • 2. The people, material, and information flow in a value stream.
    • 3. The material and information flows in a value stream.
    • 4. The steps people take in designing and producing a product.
    • 5. The detailed operation steps within cells.
    • 6. A product family matrix is used in value stream mapping to:
    • 7. Create a listing of all your products and the steps that are taken to produce them.
    • 8. Decide which products are most important to your customers.
    • 9. Identify and group products into families based on whether they pass through similar steps in your downstream processes.
    • 10. Divide the mapping teams up into groups with groups with individual mapping assignments.
    • 11. The recommended level for beginning to map a value stream for a product family is:
    • 12. Corporate wide.
    • 13. Door –to-door in an individual facility or plant.
    • 14. Across multiple facilities.
    • 15. At the process level, for example in a single work-cell.
    • 16. Calculate the Takt Time based on the following information:
    Customer demand is 34,400 parts per month. The company works 5 days per week and on average 20 days per month. There are two, eight hour shifts. Lunch is 30 minutes per shift. Two, ten minute breaks are taken per shift.<br />The calculated Takt Time is:<br />
    • 0.5 minutes per part or 30 sec. per part.
    • 17. 1 part per minute or 1 part every 60 sec.
    • 18. 0.5 parts per minute.
    • 19. 1 minute per part.
    • 20. Data Boxes on a value stream map should contain information based on:
    • 21. Engineering standards.
    • 22. The average measurements over the last year.
    • 23. The measurements on an ideal or typical day.
    • 24. What you observe on the day you draw your map.
    • 25. Give three examples of information that could go in a value Stream Map data box:
    1.________________________________________________________________________________<br />2.________________________________________________________________________________<br />3.________________________________________________________________________________<br />
    • One of the biggest mistakes in implementing Lean Manufacturing is:
    • 26. Sub optimizing by conducting Kaizen events in areas without first taking a big picture view of the organization.
    • 27. Not implementing improvements in line with organizational strategy.
    • 28. Skipping the value stream mapping step.
    • 29. All of the above.
    • 30. List the eight questions you generally ask in order to create your future state value stream map:
    1. ________________________________________________________________________________<br />2.________________________________________________________________________________<br />3.________________________________________________________________________________<br />4.________________________________________________________________________________<br />5. ________________________________________________________________________________<br />6. ________________________________________________________________________________<br />7. ________________________________________________________________________________<br />8. ________________________________________________________________________________<br />
    • A supermarket is used where:
    • 31. Processes are close together but have different cycle times.
    • 32. A customer requires specialized products from the finished goods warehouse.
    • 33. Continuous flow is not possible due to distance, unreliability, or where process serves multiple product families.
    • 34. Pull can be implemented throughout the door-to-door value stream.
    • 35. Creating value stream loops after future state mapping helps you to:
    • 36. Break your total value stream plan into manageable pieces and prioritize them.
    • 37. Communicate your plan to senior management.
    • 38. Assign kaizen teams to be responsible for each loop.
    • 39. Develop measures for each loop based on improving lead times.
    • 40. List at least three specific “forms” from your 5S course you could use and complete that would be useful in 5S activities?
    1. ________________________________________________________________________________<br />2. ________________________________________________________________________________<br />3. ________________________________________________________________________________<br />
    • 5S (choose best answer below)
    • 41. Is about standardizing the way we do things.
    • 42. Forms a foundation for all other improvement activities.
    • 43. Is a key to reducing inventory to improve lead time?
    • 44. Cannot be used in an office or administrative area.
    • 45. Match the 5S steps to their appropriate description (fill in the appropriate letter):
    5S Launch_____<br />Sort_____<br />Set in Order_____<br />Shine_____<br />Standardize_____<br />Sustain_____<br />
    • identify best locations for items, relocate out of place items, set inventory height and size limits, focus on safety, install temporary location indicators.
    • 46. Involves forming a core implementation team, identifying a project using a team charter, performing a Workplace Scan and display.
    • 47. Create rules such as holding rules and responsibilities; locations, number and position of items; cleaning schedules and procedures; storage and retrieval systems; visuals controls to share information and highlight conditions.
    • 48. Look at items in work area, red tag, keep what’s needed/eliminate what’s not, and reduce number of items to what’s required.
    • 49. Develop awareness and skills, make 5S part of daily work, get commitment from top management to make time for 5S, 5S audits, and ongoing 5S communications.
    • 50. Identify sources of containment; determine targets and assignments for cleanliness; make everything like “new”, check if replacement or repair is necessary; replace wires, hoses, tubes, etc.
    • 51. 5S efforts often fail to be sustained because:
    • 52. Everyone is involved.
    • 53. Managers don’t allow or make time for 5S activities and organizations fail to adequately implement the sustain step.
    • 54. 5S isn’t really value-added.
    • 55. Managers implement 5S but employees don’t do the work to keep it up.
    • 56. Check all that apply to goals of Mistake Proofing
    _____ Eliminate problem people<br />_____ Make product with zero defects<br />_____Remove process variables reducing opportunities for mistakes<br />_____ Make it impossible to make mistakes<br />_____ Repair defective product<br />_____ Make things right with the customer including recalls and repairs<br />_____ Immediately detect defects if they occur<br />_____ To catch and fix human mistakes<br />
    • Please match the method with the appropriate description or example of mistake proofing:
    _____Contact/Physical Contact Device<br />_____Performance Step/Motion-Step Device<br />_____Fixed-Value Device<br />_____Operator Initiated Controls/Doing It Right Device<br />
    • A parts feeder automatically counts out the nine bolts required for assembly when the operator presses a lever. The part assembled with the nine bolts isn’t allowed to leave the station unless all nine bolts are installed.
    • 57. Proximity switches mounted on sides of a blank plate trip when the blank is properly positioned allowing the machine to start. If switches are not tripped, the machine won’t start.
    • 58. Color-coding one side of a part so it is assembled with the correct side up.
    • 59. A photoelectric switch is connected to a timer; if movement of the part doesn’t occur when it should at the right step in the process (for example, it is forgotten by the operator), the switch signals the machine to stop.
    • 60. A major barrier to inventory reduction and batch size reduction is.
    • 61. Long set-up changeover times
    • 62. 5S activities
    • 63. Lead time reduction
    • 64. Material handlers
    • 65. The economic lot size model indicates a trade-off between changeover and inventory cost. One incorrect assumption with the model is:
    • 66. Fast changeovers increase flexibility
    • 67. High inventory and fast changeovers are good.
    • 68. We have to live with long set-ups and large batches; set-up times cannot be reduced
    • 69. There is a point where the cost of a changeover exceeds inventory carrying costs
    • 70. Set-up Time is typically classified in two categories as:
    • 71. Internal or external
    • 72. Value-added or non value added
    • 73. Motion and transport waste
    • 74. High cost and low cost
    • 75. Please circle the incorrect statement:

    • 80. Circle the correct statement regarding Policy Deployment and Breakthrough Objectives
    • 81. Breakthrough objectives are predominantly a supervisor function.
    • 82. Effective strategic planning should facilitate the identification of breakthrough objectives.
    • 83. Breakthrough objectives are not stretch objectives and represent small-step improvements.
    • 84. Is rarely customer focused.
    • 85. You know you have correctly identified a root cause and implemented effective corrective action through 8D because:
    • 86. You contain the effects and address the symptoms of the immediate problem.
    • 87. You have implemented a solution that meets budget constraints.
    • 88. The problem disappears so you never have it again; you can turn it off/on during testing.
    • 89. You have done a job of putting a “quick fix” in place.
    • 90. Establishing on-going controls, updating related documentation, standardizing new practices, updating personnel is part of which 8D step or steps:
    • 91. Verify corrective actions.
    • 92. Implement permanent corrective actions.
    • 93. Prevent recurrence
    • 94. Both “B” and “C”
    • 95. 5W2H (who, what, where, when, why, how, how many) is used:

    • 97. Help in the “Implement and Verify Interim Actions” phase.
    • 98. To “Define and verify the root causes”.
    • 99. Both “B” and “C”.
    <br />
    • Identify the statement that fits the proper term:
    • 100. Containment/Interim Action.
    • 101. Corrective Action.
    • 102. Preventive Action.
    _____ Action taken addresses the system failure that allowed one operator to go untrained in the first place<br />_____ Action taken to prevent occurrences of a problem which has never occurred such not allowing smoking in the building to prevent the first time occurrence of a fire in the building <br /> <br />_____ Action taken is to “retrain the operator to follow the proper procedures” in response to a problem that occurred<br />
    • Select the non-value added activity:
    • 103. Assembling two parts together
    • 104. Extrusion machine making parts
    • 105. Packing parts for shipment
    • 106. Picking up a part, putting it down and picking it up again
