Selection Matrix
Project Selection l Overall Selection Process Ø l l l Our project selection process was conducted as follows First stage was brainstorming in which team members proposed several project ideas. Second stage was drawing the expected block diagrams for each proposal. Third stage was evaluating each project and assigning them score according to the provided selection matrix, which lead to our chosen project. Ø l Project was chosen for the following reason: It is funded, meets the requirements of 1 block person and it can be prototyped and demonstrated easily. Ø l The major risks in the project: Time constraints, possible design challenges Ø l Reason for rejecting other proposals: Other projects had no external funding and were not a good match for team skills Ø Project selection was achieved through unanimous decision
Proposed Product Remote Controlled Vehicle l l l Proposed project is a remote control car, with remote controlled lights and turning signals. Car will be used during University open houses to promote the engineering department and also for kids entertainment. This will be the first UWM owned remote controlled vehicle. There is no identical project readily available in the market. Project is part of the toy industry.
