Budget – an important factor in everything that an engineer designs. The budget, is the amount of money you are able to spend on something. You might have a budget when you go shopping for groceries, a government has a budget when it plans its projects for the year, and engineers have a budget to work with when designing a solution.
Iterative Design is the cycling process of design used by engineers. The process begins with an initial trial prototype, which is then tested. The test results are analyzed, and adjustments are made. After these adjustments, a new prototype is created, and the process continues until a satisfactory product is made and produced on a large scale.
