7. This question refers to the "Claims Processing" case. A hospital processes claims and the insurance companies often reject them for coding errors. A Six Sigma team has been working on a project to reduce coding errors for the past 15 months and the data for the number and type of coding errors can be downloaded above in the "Claim Coding" file. Use this data to answer the question below. Construct the appropriate control chart for errors/claim for the last 10 ten months. What can you say about the level of statistical control? A Chart shows statistical control B Chart shows the data are not in statistical control There are out of control points on only months 14 and 6 D The control limits are narrow because of the many coding errors E The process shows a gradual improvement through the year 5. In establishing an effective and efficient process control system, which of the following represents the best strategy for implementing control charts (SPC charts) if the goal is to chart and control the process upstream, at the point of greatest leverage and closest to the source of process variability? A Chart the significant process input characteristics (Xs) B Chart all measurable process characteristics Chart the error rate of the process D Chart process equipment checklist results E Chart the process significant output characteristic (Y) 6. While you are listening to the ideas generated in a brainstorming session, which of the following is an appropriate activity? A Sort the ideas based on education of the presenter B Provide feedback to the participants as ideas are presented Write down only the ideas that bear further investigation D List all ideas without judging them E Rank the ideas as they are offered
