BSOP-326 Week 7 Fujiyama Electronics Case Study
Fujiyama Electronics Case Study - Due Week 7
Objective | Project Deliverables | Grading Rubrics| Best Practices
This case study looks at the behavior of a circuit board process though the use of Control Charts. At least two Control Charts will need to be constructed, and from them you will be asked to provide an assessment of what you see. A template to facilitate the construction of the Control Charts has been provided. You are not required to use this template. A tutorial that outlines the steps for this case is located in Doc Sharing.
Fujiyama Electronics, Inc. has had difficulties with circuit boards purchased from an outside supplier. Unacceptable variability occurs between two drilled holes that are supposed to be 5 cm apart on the circuit boards. Thirty samples of four boards each were taken from shipments from the supplier as shown in the data from the worksheet. Data in the worksheet below can also be assessed here.
The student will submit the completed case study in a Word document to their Dropbox by the end of class Week 7. The paper is worth 50 points.
The student will complete and/or answer the following questions.
Calculate X-Bar-Bar, R-Bar, and associated control limits using the data in the table above. Create X-Bar•R (Average & Range) Control Charts from the data in the table above. Discuss notable out-of-control conditions displayed in the completed X-Bar•R (Average & Range) Control Charts. Only consider points outside the control limits. Do not consider runs, set of points within certain zones, etc. If the conditions you note could be defined as assignable conditions and they are removed from the process, what will happen to the X-Bar•R Control Chart?
(a) Remove the data related to the out-of-control points you observed from the origainal data and recalculate a new X-Bar-Bar, R-Bar, and associated control limits.
(b) Create new X-Bar•R (Average & Range) Control Charts from your updated data.
Discuss how the two sets of Control Charts are different. What has changed?
The format of the case study should conform to the Publication Manual for the American Psychological Association (APA), 6th edition, for title page and text. Citations and references are not required. A basic APA tutorial can be found inthe Webliography and a paper template can be found in Doc Sharing. The completed case study will be submitted to your Dropbox as an MS Word document. All graphics and charts will be a part of the Word document and submitted as a file. Documents authored in other applications such as WordPerfect or MS Works will not be accepted.
This project is to be accomplished individually, and will reflect the work of each student. All DeVry University policies are in effect including the plagiarism policy. Late papers will not be accepted without prior permission.
Submit your Fujiyama Case Study paper to the Dropbox located on the silver tab at the top of this page by the end of Week 7. For instructions on how to use the Dropbox, read these Step-by-Step Instructions or watch this Dropbox Tutorial.
