  • Customer Needs the Objective of This Project Is to Develop a Means
    Customer Needs The objective of this project is to develop a means to assist paraplegic divers. To develop a means for assisting paraplegic divers, two paraplegic divers and two dive instructors were interviewed to get a better understanding of the problem’s paraplegic diver’s face. During the interview process, it was determined that there are a variety of different issues that paraplegic divers encounter. The problems that the paraplegic divers encounter often depend on the divers’ available movements. The diver’s available movements are determined by what muscles the diver still has control over. The interviews from the paraplegic divers and dive instructors are summarized below in Table 1.0.
