Process Control at Polaroid

EXECUTIVE SUMMARY

The Polaroid case emphasizes the importance of quality and process control procedures. Materials represented the majority (2/3) of manufacturing costs at the R2 plant. This fact alone reflects that quality control, yield maximization and minimization of scrap were crucial at the plant and for Polaroid as a whole. Undoubtedly, internal failure costs (scrap, rework, process failure) and external failure costs (customer complaints, product return, lost sales) can be extremely significant in this industry. By 1984, there was intense pressure to limit and reduce costs, thus giving rise to the implementation of Project Greenlight. The objective was to reduce quality monitoring costs, while maintaining or improving product quality. By instituting statistical process control procedures, production would be capable of manufacturing product within specifications and of a more consistent quality. Results of sampling identified an issue with finger height process average. Under the project, this would call for shut down, maintenance/recalibration and new control limits. While it can take some time for all personnel to develop the proper skill set and trust of fellow employees to fully utilize SPC, the end result will provide less scrap, higher yields and more consistency of product.

ANALYSIS & CASE QUESTIONS

1. What is the magnitude of cost of quality problems at the R2 plant? How effective were its past procedures for quality management?

Expensive materials represented about two-thirds of the cost of manufacturing at R2. Cost of quality issues are only magnified because of the nature of this particular manufacturing process and the dollar value associated with QC and the scrap created. For example, in 1984 sampled scrap accounted for $540,000, operator-sampled scrap another $740,000, and rejected

Case Study #2

...Case Study #2: Internal Control Most companies that start off as a private corporation want to ultimately become a public company in the future. Becoming public usually provides businesses the opportunity to raise capital in hopes of expanding. There are definitely some pros in becoming a publicly traded and owned entity. LBJ Company is considering going public in the future, and they are requesting the writer to evaluate their internal control systems. They would also like to be made aware of any new internal control requirements if they decide to go public. Lastly, they would like to know what they have been doing right and what they have been doing wrong, and whether or not they should purchase the indelible ink machine. The writer will now inform the president of LBJ of any new internal control requirements if they decide to go public. Internal control consists of all the related methods and measures adopted within an organization to safeguard assets, enhance the reliability of accounting records, increase efficiency of operations, and ensure compliance with laws and regulations. Internal control systems have five primary components and they are as follows: • A control environment. It is the responsibility of top management to make it clear that the organization values integrity and that unethical activity will not be tolerated. • Risk assessment. Companies must identify and analyze the various factors that create risk for the business and must determine how to manage...

Altona Corporation Memo

...Altoona wishes to capture the available 30-35% market share their forecasts predict. Second, the two major problems involved in the coating process (dirt and pocking) have made the coating process itself inconsistent and unpredictable. At least half of all defects occur in the coating process. In 61 samples of 300 units, the mean defective rate for dirt was just under 5% and 3.5% for pocking. Quantitatively, there are also two main issues: First, the one attribute that is critical to quality in the eyes of the customer, visual inspection, varies too greatly. It has become a costly and frustrating quality measure for both customers and Altoona. Second, employee, specifically engineers’, time is being mismanaged and resulting in forgotten projects, needless wage expenditure, and difficulty with experimentation. Together, these four problems will be counteracted with a quality management system that utilizes and builds on the current SQC initiative where the goal of getting dirt defects to fewer than 4% can be realized. The quantitative issues referred to above will also be addressed with appropriate project design plans and stable operations. Altoona currently faces problems with standards of certain dimensions of quality. To isolate three of these dimensions individually is critical – especially to the success of the coating process. These dimensions are:...

Change Control

...Change control Change control is one of the more important subjects of the business world today. With the ability to transfer information at (nearly) the speed of light, competition can be fierce. In a competitive business environment, there is tremendous pressure to be one step ahead of (or to rush quickly to catch up to,) the competition. This is especially true in industries where technology is the main source of business. Even where it’s not, almost every company has a Web site now. The temptation to make changes to these production environments can be great, and management can and will often pressure people to make the change happen now. This is why change control is important. Information security and business continuity while continuing to offer the highest-quality product should be the goals of any information technology group at a very high level. Sometimes, though, one can buckle to the pressure of management or simply decide to change something in a way he or she thinks better. While this may be true at the laser-point level of that particular module, application, Web page, etc., the real problem exists in how the change cascades down to other items. That is to say, the one small change made to item “a” may have a trickle-down effect and break seemingly unrelated item “z” or even reporting somewhere. If this breaks financial reporting, anything from auditing to bankruptcy is possible. It can even create a legal situation because a product or...

...Denew Assignment Accounting Assignment 2: Manufacturing Overhead Borealis Manufacturing has just completed a major change in its quality control (QC) process. Previously, products had been reviewed by QC inspectors at the end of each major process, and the company's 10 QC inspectors were charged to the operation or job as direct labor. In an effort to improve efficiency and quality, a computerized video QC system was purchased for $250,000. The system consists of a minicomputer, fifteen video cameras, and other peripheral hardware and software. The new system uses cameras stationed by QC engineers at key points in the production process. Each time an operation changes or there is a new operation, the cameras are moved, and a new master picture is loaded into the computer by a QC engineer. The camera takes pictures of the units in process, and the computer compares them to the picture of a “good” unit. Any differences are sent to a QC engineer, who removes the bad units and discusses the flaws with the production supervisors. The new system has replaced the 10 QC inspectors with two QC engineers. The operating costs of the new QC system, including the salaries of the QC engineers, have been included as factory overhead in calculating the company's plant-wide manufacturing-overhead rate, which is based on direct-labor dollars. The company's president is confused. His vice president of production has told him how efficient the new system is. Yet there is a large increase in...

Evaluation

...For a process to be adequately controlled and manipulated, the variable of interest in the process (e.g. Temperature, Pressure or Flow) often called the Process Variable (PV) needs to be measured by a sensor which converts the measurement into a suitable signal format (4 – 20mA or digital) and then transmit it to a controller which makes the control decision and finally acts on a final control element in the control loop. What does this signal transmission is referred to as a transmitter. The schematic below illustrates the interactions between all the elements in the control loop: | Elements of a Process Control Loop |   What is a Transmitter? A Transmitter is a device that converts the signal produced by a sensor into a standardized instrumentation signal such as 3-15 PSI air pressure, 4-20 mA DC electric current, Fieldbus digital signal etc., which may then be conveyed to an indicating device, a controlling device, or both. The indicating or controlling device is often located in a centralized control room. The transmitter often combines a sensor and the transmitter in a single piece. The sensor measures the process variable and generate a proportional signal. The transmitter then amplifies and conditions the sensor signal for onward transmission to the receiving or controlling device. | -->   Transmitters Used in Process Instrumentation: Transmitters can be broadly divided into two broad groups: (a) Electronic Transmitters (b) Pneumatic Transmitters ...

...MANAGEMENT: SUMMARY FOR FOUNDATIONS OF CONTROL NAME OF TUTORIAL LECTURER: ENCIK SATHISWARAN A/L UTHAMAPUTHRAN TUTORIAL GROUP: L1T3 NAME: CH'NG WEI MING MATRICES NUMBER: A13A0122 SUMMARY In chapter 14 for the fundamentals of management, the important thing that we will learn after studying is : explain the nature and importance of control; describe the three steps in the control process; discuss the types of controls organizations and managers use and discuss contemporary issues in control. For explain the nature and importance of control, control is the management function that involves monitoring activities to ensure that they're being accomplished as planned and correcting any significant deviations. The purpose of control is to ensure that activities are completed in ways that lead to accomplishment of organizational goals. Control is important because it's the only way that managers know whether organizational goals are being met and if not, the reasons why. The value of the control function can be seen in three specific areas which is planning, empowering employees, and protecting the workplace. As the final step in the management process, controlling provides the link back to planning. If manager didn't control, they'd have no way of knowing whether goals were being met. The second reason controlling is important is because of employee empowerment. An effective control system can provide information and...

...Week 5 Individual Assignment: Process Improvement Plan Justin Sciarro OPS 571 November 26, 2012 Barry Haigh Process Improvement Plan During week one the process of pulling patient room trash and linen was analyzed. The steps included the designing of a flowchart outlining the steps of the actual process, while identifying factors and metrics. The remainder of this paper will focus on process improvement as it relates to control limits and confidence intervals. Moving on, in this case, process control is concerned with monitoring quality while the service is being performed (Chase, Jacobs, & Aquilano, 2006). The two types of variation within processes are assignable and common. Assignable variation is defined by factors that can be clearly identified and perhaps even managed, while common variation or random variation is simply natural in the process itself (Chase, Jacobs, & Aquilano, 2006). Regarding the process of pulling patient room trash and linen, assignable variation included collection/disposal methods and trash liner compatibility/fit. After evaluating these variations, it was determined they could be effectively managed through alternative options. For example, since the trash and linen is collected using separate receptacles, the linen is left in a staging area where it is picked up by a third party vendor each evening. However, the trash, once collected, is disposed of into a large compactor. This particular task can be time consuming; therefore, it...

Optimization in Production Operations

...Optimization in Production Operations Optimal “Lean Operations” in Manufacturing By Carlos W. Moreno © 2005-06 Ultramax Corporation Oct. 5, 2006 Introduction This essay deals with production / manufacturing operations: with their economic impact (or other metrics) while making product with the existing process, usually driven to satisfy: • market demand (delivered: volume, quality) • • economics (incurred: cost savings, resource utilization); and safety (safeguarding equipment, personnel and environment) These drivers represent the main impact of production on company profits, with short-term and long-term effects on the P&L Statement. The bottom line is that most production processes are underutilized; and the use of mature, accessible mathematical technology unlocks that latent capacity, which is of significant value. The best possible performance is “Optimal Operations.” In the process industry it is called “Process Optimization.” In manufacturing it is the extreme of Lean Operations, one of the components of “Lean Manufacturing” success. Other components that qualify for “lean” in the sense of avoiding waste (non-value-added), and not missing opportunities for improvements are: “Lean Design” (the most common emphasis today), “Lean Logistics – and Supply Chain,” “Lean Maintenance,” “Lean Scheduling,” “Lean Safety,” and “Lean Scheduling.” Some share interests with Six Sigma as well (quality and costs). All these solutions are also part of the classical field of Industrial...

Discussion 1

...Internal controls are referred to the methods established by a company to safeguard its assets. Internal controls are designed with the idea of achieving a company's objectives, which include the effectiveness and efficiency of operations, that the information presented to financial statement users is reliable, and that the firm is complying with regulations and laws (Bodnar & Hopwood, 2013, p.13). Internal control requires the distribution of responsibilities among employees. It is important for employees to know their task or job function in an entity since they will work harder to control these responsibilities. One example of an internal control placed in a company is the segregation of duties, which implies that the same department or person does not have control upon accounting and financial responsibilities (Bodnar & Hopwood, 2013, p.14). Internal control has an important role in the development of Accounting Information System (AIS) since the success of AIS depends on the effectiveness of the internal controls of a firm. AIS is defined as the transformation of financial and other data, collected by people and equipment, into information. The effectiveness of internal controls assure that the data entered by employees of a company in a computerized system, the techniques used to process information, the methods used to store information, and the information produced are accurate and appropriate Internal controls are designed to monitor and keep the quality of...

Inventory Control

...Quality Control Theory Jonathan Agee, Steven Bonilla, Joseph Eastman, Chris Ibarola, and Bruce Kleinknight American Public University Abstract Quality. It's one simple word that in today's marketplace means the difference between greatness and bankruptcy. It's what separates the pretenders from the contenders. Because of the large availability of products on today's market, quality has become a major factor in people deciding factors. Gone are the days of old when companies could produce a product of sub-par quality and be profitable because the competitors were out of the market place. With quality being such a huge deciding factor these days with customers, it would be financially ruining if managers produce a product lacking in quality. Just try to fathom if car companies like BMW would be around if they produced poor products. Imagine showing up to a BMW dealership to purchase a "Melbourne Red Metallic" car only to find every red car was a different shade from the other. To prevent these catastrophic business practices, companies have created a control process to compare their new products to a set standard. It's this continued quality that keeps the customer and creates a successful business. Throughout this report, we will explain how companies can ensure their success by controlling the quality of their products. Before we get into the models and examples of quality control, we fist must have a basic background understanding of the concept. Quality is defined...
