The correct choice is b. Requirement definition is the first phase in system engineering. Therefore, the developer should not start the design or implementation before defining and analyzing the requirements. (Same reason for why d is true.) Exploring the solution space and comparing different solutions in terms of cost, efficiency and reliability is necessary before selecting an answer. (Therefore, e is true.)

Question 2:
The correct answer is c. This is especially observed with Tyler, Texas radiation therapy overdose deaths and Denver International airport baggage handling system. Therapies were not done through the software ...
