The auto oil change typically includes not only changing the engine oil but also changing the oil filter, tire rotation, brake pad inspection, tire pressure check, fluid level checks, belt and hose checks. See the attached Auto Maintenance Service Process flowchart.

1. Describe the purpose of any process flowchart, not necessarily this flowchart.
2. Explain why the Auto Maintenance Service Process flowchart would, or would not, be useful to a service manager. Explain why it would, or would not, be useful to a service mechanic.
3. Explain the meaning of the terms value-added and non-value-added as they relate to process steps. Identify three steps in the Auto Maintenance Service Process that add value to the customer and explain why. Identify two steps that do not add value to the customer and explain why. Does this mean the two steps do not add value at all and so should be eliminated? Explain.
4. One obvious metric would be the time required to complete the service process, but the time is different depending on whether one sees the process from the customers perspective, or the managers perspective, or the technicians perspective. Would it be helpful to keep track of one, two, or all three of the times? Explain.
5. Explain the meaning of the terms leading metrics and lagging metrics, with an example from this process. Explain what lagging metric, or metrics, would be appropriate. Explain what, if any, leading metrics would be appropriate?
