Polaroid Process Control

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?

3) Compute limits for the sample mean X around μ=12 such that, as long as a new sample mean is within those limits, the process will be considered to be operating satifactorily. If X exceeds the upper limit or if X is below the lower limit, corrective action will be taken. These limits are refferred to as upper and lower control limits fro quality control purposes.

While we are performing our analysis on different aspects of the company, we look at the three main types of cost. When we remain devoted to improving our costs, and the faults related, we show our same devotion to our consumers. This is portrayed by the quality of products we put on the shelves. Prevention costs, appraisal costs and Failure costs are areas

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

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

However, as a new member with a new product, electronic product in North American market, the reputation is also an important attribute. Especially, quick delivery time is a key attribute for this company, due to the demand of quick delivery in all markets. Moreover, the manufacturing process of the new product, electronic product, on which our company will definitely focus, has a lot demands. Such as, technology, innovation and quick delivery time even the ability to make the product be the first one appearing in the market (other company, which is developing the same product, may become our competitive opponents). Especially, technology is predicted to play the most important role in the manufacturing process. On the other hand, the traditional cost system has a lot of limitations. Traditional costing system focuses on the cost reduction and the efficiency, particular the products with relatively few standardized components; Clifton, however, produces a wide range of airplane components. In addition, nonfinancial aspects of

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.

5.  Assuming that operators will continue to take samples of 10 sheets each hour to check if the process is in control, what control limits should Douglas set for the case when extrusion is a 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.

Wriston’s Detroit plant is no longer a viable operation due to long-term capital underinvestment and product-process mismatch. It is recommended that the plant be phased out of operations over a five-year period with production and staff gradually shifted to a new plant to be built in the Detroit area. Further, it is also recommended that division accounting procedures and evaluation mechanisms be modified to allocate revenues/costs allowing for the synergistic benefits of Detroit’s products, and to recognize inherent manufacturing complexities, respectively. Issues Detroit’s production is unique when compared to other Wriston plants. Runs are typically lowvolume, involve significant set-up time, and vary significantly due to the sheer

* Introduces the construction and use of statistical process control (SPC) charts and an understanding of the relationship between SPC and conformance quality.

This paper aims to support Natalie York, the operations manager at Harnswell Sewing Machine Company (HSMC), in her intent to improve product quality in the company. In addition to analyzing production process data of half-inch cam rollers and explaining the results, this paper also gives advice on which actions Natalie should take and how she should approach the CEO and founder of her company.

26.   A control chart is used to monitor the fraction of defectives generated by a process is the:

In late March 1996, Ralph Norwood was faced with the task of restructuring Polaroid’s capital structure. In the past, Polaroid had a monopoly in the instant-photography segment. However, with upcoming threats in the emerging digital photography industry and Polaroid experiencing recent losses in their market share due to Kodak’s competition, Gary T. DiCamillo, recently appointed CEO of Polaroid, headed a restructuring plan to stimulate the firm’s performance. The firm’s new plan has goals such as to aggressively exploit the existing Polaroid brand, introduce product extensions, and enter new emerging markets such as Russia in order to secure Polaroid’s future.
