According to scenario, Susan Douglas is the vice president of quality at Flyrock tires. She was not sure how to communicate the quality standards of Six Sigma to the people of her organization. Flyrock had five manufacturing plants in the United States, and had another 20 facilities for other components used in the tire. Though Flyrock has always emphasized on quality issues, it has had a bigger concern over quality in the recent times, because of the recent fatal accidents involving tires made by other manufacturers due to tread separation. There was significant media coverage over the incidents and the manufacturers had a lot of pressure in improving quality. Douglas wanted to push through a quality control management program in order to improve the quality at Flyrock. For that she needed to build a solid case first (Article).

There was a major quality issue at Flyrock. It had very little or no monitoring during the processes for quality control. “Given the large number of steps in building a tire, errors tended to accumulate. As a result, even if each step produced only 1 percent defects, at the end of 20 steps only 81.2 percent of the product would be of good quality. Since each factory produced about 10,000 tires per hour, such a process would result in about 1,880 defects per hour. Thus, it was very important that each stage had a high level of quality (Article).”

The problem of quality control can also be seen clearly at another point. “Adhesion flaws and other internal problems were not visible (Article).” Therefore manufacturers pull out randomly one tire out of the production line and cut them apart and check them. By this, it is evident that the quality

Quality Assurance In Health Care

...Quality assurance was born in the industrial setting in the 1950s. There it stayed, evolved, and thrived until the early 1990s when it made the crossover into the health care arena, (Sollecito & Johnson,p 20 2013). In the modern era, striving for excellence and the assurance of quality is a staple of health care and, with the transition to pay-for-performance and evidenced-based practices in medicine, it is becoming more important and more visible. In the healthcare setting, quality assurance (QA) teams work throughout the hospital system to design policies and procedures that promote the best possible outcomes for their patients and, in turn, their facility. That means ensuring compliance with a multitude of regulations, policies, and laws...

Mhm505 – Introduction to Quality Assurance

...TUI University Michael Reeves MHM505 – Introduction to Quality Assurance Module 1 Case Quality Assurance (QA) can be defined as those activities that contribute to designing, mentoring and the improvement of quality healthcare. In defining the quality we need to develop the standards that will be used to measure the effect of the quality of work we are striving towards. The standards does not have to be clinical it can be administrative, good standards are usually reliable, realistic clear and valid. With the amount of medical mishaps that we experience on a daily basis it is very important that we have a quality Assurance team in place. In fact an entire department should be available just to focus on quality operation within the hospital. With a solid quality assurance program I know that a hospital will be able to save even more money and resources by avoiding law suits that arise from malpractice. I would base my argument on areas such as communication, situational awareness and the importance of quality patient care. In my opinion the aspect of quality assurance that is most important is safety, this falls in the range of focusing on the patient or putting focus on the system or even the processes that are in place. It is obvious that the purposes of health care services are to generate customer satisfaction and operate with the least amount of money possible. Focusing on the client does...

...Quality Assurance ITS 400 – Information Technology Project Management Colorado State University- Global Campus Professor Britton September 18, 2014 Quality assurance is the, “…systematic process of checking to see whether a product or service being developed is meeting specified requirements” (Rouse, 2007). Quality assurance is particularly important in human resources. Employees bring life to the goals of an organization and can impact the morale and culture of the work environment. This specific organization is interested in hiring new instructors to teach a project management course. These instructors will help future project managers develop the skills needed to direct individuals in implementing new ideas. This makes the instructor the most important piece of the course, as their work will dictate the success of future projects. When hiring new instructors, human resources should use the following quality standards: competence, compatibility, commitment, character, culture, and compensation (Hall, 2012). These standards will aid human resources in determining if the possible candidate can help form the kind of project manager needed for the job. They will also allow the company to look at current instructors and evaluate if they hold the qualities that they are looking for. If not, the company can administer trainings and have individual meetings to address the topic. Project management requires dedication, perseverance, and patience. Instructors of these...

Quality Assurance in Food Industry

...The design I have proposed below is for a Food Processing Company characterized by low technology but a need to have a Quality Assurance Program. Terminology I would like to start with the Terminology because of the several different usages of the term ‘sample’ and ‘test material’. Sample is used for the part of a larger “lot”(e.g a consignment, batch, carton, container and load ) which is sent to the Laboratory for analysis. When the sample is received by the laboratory it becomes a “test material”(Codex Alimentarius, AOAC International & IUPAC) . The Laboratory is responsible for its “traceability” and for its “integrity”. Sampling & Analysis “QA is the sum of all the activities taken to ensure that the information generated by the Laboratory is correct ( Wilcox et al., 1978 )” It is important that Laboratory is involved in discussions on sampling plans and in determining the sample sizes. Confidence in the decision meets/fails to meet a specification is dependent both on (a) the effectiveness of the sampling plan in obtaining a sample which is representative of the lot (b) the quality of the analysis carried out on it. Quality Assurance Program “Without a defined Quality Assurance program all analytical result must be suspect. ( Harnly & Wolf 1984 ).” The identity and integrity of materials being handled by the Laboratory must be ensured throughout the time when they are under the control of the Laboratory, e.g. from sample receipt to data report and authorized...

Hank Kolb, Director of Quality Assurance

...Director of Quality Assurance Group 17 Navid Razavi Frederike Schmidt Introduction The Case “Hank Kolb, Director of Quality Assurance” is about a production line of an industrial product plant, called “Greasex”. The text deals with several manufacturing problems, within the production of spraying cans for the high-technology sector, of “Greasex”, which arise from the contradiction of interests between the quality and manufacturing department, due to time pressure in the production. First of all, the spray cans of “Greasex” have a quality issue. Due to the high pressure in the cans, there is an accidental risk for customers which could lead to a fatal image loss of the company. There are several causes mentioned by the director of quality assurance. The untrained operator for the filling equipment and the time pressure of the manufacturing personnel leads to mistakes and inaccuracies during the production. Furthermore, there is no regular maintenance of the filling equipment, which is also very old and not designed for the production line “Greasex”. This leads to high non-standard downtimes of the production process and causes the time pressure of the manufacturing personnel. Because of the time pressure coming from the production-planning department, there is an inadequate supply of nozzle heads, an important part of the cans. Due to the unbalanced amount of this parts, the company is giving rush orders to the suppliers, which ends in a lack of quality of the nozzle...
