Defining Your Design Defining Your Design ProblemsProblems
Recognize and define the ProblemRecognize and define the Problem – – When When defining the problem, consider the boundaries, the defining the problem, consider the boundaries, the parameters, and the limitations. A very narrow, well parameters, and the limitations. A very narrow, well defined, specific problem will be easier to solve than defined, specific problem will be easier to solve than a board, all encompassing generation. Think about a board, all encompassing generation. Think about what has been discussed in class including the what has been discussed in class including the limitations of the dragster.
