Voice of the Customer

Comments by Hensel

Note that during the AY2009-10 academic year, the DPM students did not complete the customer needs during the fall term, and thus much of the detail regarding customer needs were deferred to the first several weeks of MSD 1. As a result, each individual project team in the roadmap created their own interpretation of the general needs that were outlined previously by the students in DPM. Each of the VOC tables generated by the individual project teams are shown in the tables below.

While the students in the MSD teams have grown to develop a reasonably complete set of customer needs, and turn them into engineering performance specifications, this took several weeks of effort in MSD. For future terms of DPM, our goal will be to fully develop the customer needs, including measures of effectiveness, for the entire roadmap family prior to the conclusion of DPM.

As you review the tables below, please make note of the following items that future DPM students should do differently as they prepare roadmaps for other project families, or as this roadmap is refined.

P10203 Motor Controller - Land Vehicle - Voice of the Customer
Need # Importance Description Comments / Status
CN1 3 The controller is easy to manufacture and assemble.
CN2 4 The controller is modular, (can be configured in several different options to support varied functionality).
CN3 5 The controller has a low risk implementation and is stand-alone. Controller operates as intended even if other groups fail to finish.
CN4 5 The controller is able to properly interface with the other modules of the Land Vehicle Platform.
CN5 4 The controller is able to be used by first year mechanical/electrical engineering students.
CN6 3 The controller is able to make the platform move with sufficient agility and controllability. Sufficient is described as at the same level or better than the RP1.
CN7 3 The new design shall improve upon the aesthetics of the RP1.
CN8 2 The controller makes effective use of the space provided by the Chassis. Space effectiveness refers to minimizing overall space requirement without sacrificing cost or performance.
CN9 5 The new design is cost effective, (cheaper than the RP1 with the same, or improved performance characteristics).
CN10 4 The controller is durable and can withstand repeated use with minimal maintenance.
CN11 2 The controller has a reasonable battery life. Reasonable refers to a level at or above the RP1.
CN12 2 The controller is able to be upgraded by future Senior Design teams with little redesign or component replacement needed. Upgrade is used to refer to the fact that a CE team could be given the controller to add software functions to the system.
CN13 3 The Controller makes use of Prior Generation's Designs and Research.
