Polaroid Case Objectives * Introduces the construction and use of statistical process control (SPC) charts and an understanding of the relationship between SPC and conformance quality. * Creating the strategy and implementation steps for transforming an operation from inspection-based to one that relies on statistically controlled process. * Understanding the complex human and organizational problems that occur when the basic operating philosophy is changed. * Applying quality tools to assess the root causes of defect problems. * Understanding the limits of product sampling and inspection methods, especially for a product that is destroyed by the inspection process itself Assignment: In the mid 1980s, one of …show more content…
First, both R-charts show subgroup ranges that are within the control limits, which suggests that the variation between subgroups is consistent. However, we can clearly see from the X-bar chart for finger height that this process is not in control. Moreover, this seems to be a substantial problem, as these limits are violated frequently. Exhibit 5 shows the graphs for finger-height and pod-weight in each shift. The pod weight graphs for Shift A, B and C shows that processes are in control. Finger height graphs for shift B shows that process is out of control as several points fall outside of the control limits. Finger height shift A and C are in control but many points are close to upper control limits in the X-bar charts. From this analysis we conclude that the process involved in finger height is problematic and should be optimized before moving forward on analysis of other parts of the overall process. The regular violation of control limits may point to a significant contribution to overall quality control rejections. III. Quality Check “Type of Defects” (exhibit 4) and “Reported Defect Rates” (exhibit 5) suggests that the output quality of R2 has declined. The reported defective rate from the operators had decreased from under 1% to 0.5% and the defective rate from the central process auditors had
13. Which of the following characteristics makes it EASIER to measure the quality of a service, relative to that of a product or facilitating good?
Assuming that Kodak Gold Plus sells about 20% of its yearly sales during off-seasons, the resulting cannibalisation will amount to:
A process that monitors standards by take measurements and corrective action as needed. It is in control when only variation is natural, if variation is assignable then discover cause eliminate it. Take samples to inspect/ measure- reduce inspection time, reduce opportunity of bad quality. Control charts graph of process data over time-show natural and assignable causes. Control charts for variable data (characteristic that is measured, length,height, etc) are X-chart (average) and R-chart (range)must use x and r to get correct results. central limit theorem follow normal curve. When we know . When we don’t know . Control charts for attributes (categorical-defective, good/bad) P-chart (percent) or C-chart
We need to know the normal range of movement of the muscles and joints so when moving, handling and positioning a person we know the limits of each limb. We need to take into consideration other factors that may inhibit a person’s movements as:
This result shows that he bad with he’s coordination as he only reached the average result because this was he’s best result after trying this test 3 times.
● Monitoring — Internal control systems need to be monitored–a process that assesses the quality of the system’s performance over time. This is accomplished through ongoing monitoring activities, separate evaluations or a combination of the two. Ongoing monitoring occurs in the course of operations. It includes regular management and supervisory activities, and other actions personnel take in performing their duties. The scope and frequency of separate evaluations will depend primarily on an assessment of risks and the effectiveness of ongoing monitoring procedures. Internal control deficiencies should be reported upstream, with serious matters reported to top management and the board.
Quality Associates, Inc. is a consulting firm that advises its clients about sampling and statistical procedures that can be used to control manufacturing processes. In one case, a client provided Quality Associates with a sample of 800 observations that were taken during a time when the client's process was operating satisfactorily. The sample standard deviation for these data was .21, hence, the population standard deviation was assumed to be .21. Quality Associates then suggested that random samples of size 30 be taken periodically to monitor the process on an ongoing basis. By analyzing the new samples, the client could quickly learn whether the process was operating satisfactorily. When the process was not operating
a. How does Polaroid’s distribution needs vary by subsidiary in Europe? What are the implications of these differences? You must consider the cultural diversity of the countries in Europe where Polaroid operates.
Flexibility can be defined as the capability of something to bend easily without breaking. The flexibility of a person is commonly measured during fitness tests, and the most frequently used test of a person’s flexibility is the sit-and-reach (Jackson and Baker, 1986). Though it is commonly accepted that the sit-and-reach produces an accurate and relative measure of a person’s flexibility, the validity of the test has been examined a number of times (Jackson and
Polaroid Corporation, headquartered in Cambridge, Massachusetts, was a company marketed a wide variety of instant photographic products for consumers and industries. After the deregulation of US motor industry consolidation of the warehouses in US took place, which resulted in an improved service level and reduced costs. Overwhelmed by the consolidation results, the management wanted to consolidate the subsidiaries’ warehouses in the Europe to a direct distribution.
Quality Associates, Inc., a consulting firm advises its clients about sampling and statistical procedures that can be used to control their manufacturing processes. In one particular application a client gave Quality Associates a sample of 800 observations taken during a time in which the client’s process was operating satisfactorily. The sample standard deviation of this data was 0.21; hence with so much data, the population standard deviation was assumed to be 0.21. Quality Associates then suggested that random samples of size 30 be taken periodically to monitor the process on an ongoing basis. By analyzing the new samples, the client could quickly learn whether the process was operating satisfactorily. When the process was not operating satisfactorily, corrective action could be taken to eliminate the problem. The design specification indicated the mean for the process should be 12. The hypothesis test suggested by Quality Associates follows.
a) Under this condition, what proportion of defective sheets will the extruder produce (for the Six Sigma process)?
Issue: Dynamic Seal, a precision parts manufacturer with a reputation for high quality, does not currently utilize a Statistical Process Control (SPC) system. However, United Airlines (UA), a major customer representing 14% of Dynamic Seal’s business, insists they implement an SPC system or loose United Airlines’ business. In addition Dynamic Seal do not have a sound preventative measure quality control system in place, preferring 100% inspection to cull bad quality, rather than building parts correctly from inception.
The case is based on an insurance service company which traced back to 1994. The company was facing problems in controlling and improving service quality and operation performance. This essay will stress on introducing the SPC (statistical process control) to DAV and providing suggestions on improving both the SPC and the company’s operation performance. The five questions required are covered and allocated
