Based upon our research and our discussions with the customer we were able to populate the customer requirements of the QFD chart. Customer needs or requirements are stated on the left side of the matrix as shown in the diagram above. We decided to include the most basic to the most detailed design elements to include in this chart. The most basic elements are easy to be overlooked; however they are some of the most important and crucial to the function of the design.
The shapes filling the chart were chosen based upon the strength of the relationship between a customer requirement and the engineering characteristics of the design. The level of impact and consequent consideration of each aspect in the design is represented by ɵ, o, or ▲; ɵ indicates a high relationship, o is for a moderate relationship, and ▲ indicates a low relationship. Customer importance was based on a scale from 0 to 30 where thirty is being the most valuable feature to the customer. The QFD was made to accommodate the customer in all ways possible, but not all of the engineering characteristics can be easily attributed to the requirements. From the QFD, it was shown that the algorithm is very important to program the sensor, the motors and wheels, and position beacons. The sensors are required to detect and avoid obstacles, the motors to provide movement and the position beacons are to determine specific locations. Those three components have very strong positive correlations with the decision algorithm, and they have the highest relative weight with respect to the customer needs. Our target is combing all the customer needs and technical requirements in order to produce a device that satisfies our customer.
