2.5 Prototype Prototype is an early sample or model formed to proof a concept or process or to replicate it so that we can learn and make a better final product. According to Richard C. Levy, prototype means an original model on which something is patterned. With the use of CAD model in design stage, we created prototype with using different types of techniques based on the project and budget requirement. Prototype can be divided into three major types. The first type is proof of concept prototype which is also known as breadboard. This type is essentially to show the basic functionality of the product. It does not look like the exact final product which need to look good or work well. The second type is presentation prototype which is a …show more content…

DFR is important for the companies because warranty cost and customer satisfaction. Reliability is one of the important dimension of quality products which defines as the products tendency to perform constantly throughout a specific period. Two elements in reliability are time and failure rate. For example, the smartphone battery might have a reliability of 99% over the next 10,000 hours. It has a 99% chance to run normally in this time but 1% chance of being …show more content…

The first step is illustrating the product or process and its function. The second step is developing a block diagram to show the components of the product. Next, determine the failure modes which the component or subsystem possibly fail to meet the design. The fourth step is finding the effects for each failure modes. The engineer has to find what the ultimate effect for each failure mode. The fifth step is determining the severity of the effects based on numerical ranking started from no effect (1) to very severe (10). The engineer needs to categorize the severity into four types, namely catastrophic, critical, marginal and negligible. The sixth step is discovering the causes for each failure mode. The possible causes should be documented and ranked in scale of not likely (1) to inevitable (10). The seventh step is identifying the current design controls and decide the probability of detection. Then, identify the highest risks based on Risk Priority Numbers (RPN). The last step is recommending action taken to remove the highest
