CASE STUDY You have been assigned the task of making a preliminary recommendation for the material to be used in the bumper of a new ultra-safe crash-resistant automobile. It is particularly important that the bumper be able to survive the energy levels associated with low-velocity crashes, without damage to the bumper of the automobile. Even more important, for high energy levels associated with severe crashes, the bumper should be capable of deforming plastically over large displacements without rupture, thereby dissipating crash pulse energy to protect the vehicle occupants. It is anticipated that these new vehicles will be used throughout North America, and during all seasons of the year. A 10-year design life is desired. Cost is also an especially important factor. Propose one or a few candidate materials suitable for this application. (Specific alloys need not be designated).

Aurora Electronics has received a large number of customer complaints and returns for a DVD player that it manufactures. When a DVD is inserted into the loading mechanism, it can become stuck and difficult to remove. Consumers will attempt to pull out the DVD drawer with their fingers or pry it open with an object such as a knife, pencil, or screwdriver, frequently damaging the DVD or injuring themselves. What are the various costs of poor quality and quality assurance that may be associated with this quality issue?

Case Study : Neutraizing the Concordia Effect Communication has become crucial in Costa Cruises (the Italian cruise company owned by Carnival Corporation). In recent events, the Costa Concordia keeled over off the Italian coast near the island of Giglio in Tuscany, Italy, in January 2012 and the Costa Allegra was hit by fire and drifts in the Indian Ocean a few weeks later. Captain Schettino's preliminary abandoning of the Costa Concordia as well as his denial to return onboard the sinking ship brought into question the competence of the company crew as well as the effectiveness of recruitment procedures. After a few days of the company stressing that the complete responsibilities of the accident were attributed to the captain, Costa Cruises decided to suspend all social media activities as a sign of respect for the victims and as an attempt to prevent inappropriate comments. However, the lack of disclosure and the distorted information coming from other media aroused contrasting…
