The objective of this project is to understand what user trade-offs were selected and prioritized when each of the three systems were being developed. The Systems to be analyzed will be: • 2012 Audi S4 Sedan

• 2012 BMW M3 Sedan
• 2012 CLS63 AMG Sedan

In order to understand this relationship, a reverse engineering concept will be done using the QFD-HOQ model on all three of the above systems. Traditional Enginnering concepts will be utilized during the system analysis making design considerations (i.e. speed vs. weight vs. acceleration) all of these systems. It will be according to reverse engineering and the importance of each user requirement associated with the system by paying specific attention to the relationship between the voice of the customer and the engineer.

3House of Quality Summary

Whether a cascaded set of houses of quality or a simple top level what vs. how matrix is used, a quality function deployment is a labor-intensive process. Essentially, it invests time in planning to reap a profit in a shorter overall development cycle, based on an insight into the customers' wants. The same insight should also minimize the need for redesign. An illustration o HOQ can be found below.

4System Analysis

Reading the chapter before you can realize that there is a linear thinking in terms of compliance with costumer requirements the linear thinking would be the technical requirements in order to attend the customer requirements.

The Systems will be analyzed in terms of reengineering of those systems.

4.1 Voice of Costumer (Costumer requirements). Assumptions

For the analysis of those three systems we will have as costumer requirements the following items. • Engine Power
• Cabin Size
• Handling
• Safety
• Price
• Comfort ability
• Warranty
• Speed
• Reliability
• Fuel Efficiency
The Costumer Requirements have been defined by the author of this work referring the author as the customer. The Costumer Requirements defined in this work are costumer requirements of the author acting as the costumer of the three systems. The author defined those requirements reading reports[ii] from the reference source. Those requirements were selected based on most as common requirements.

4.3 Engineering hypothesis of the analysis.

The utilized hypothesis is the observation of the apparent correlation between the voice of engineering (Technical Requirements) and Voice of Costumer (Costumer requirement). It holds that, people who claim science expertise whilst advocating creationism tend to be dedicated to attend the customer requirements via science expertise evaluating the level of effort and difficult. This hypothesis does not address whether engineers tend to be creationists; however, it has been speculated that engineering predisposes people to a creation science. For the analysis of...
