1. With the benefit of hindsight, what steps could have been taken during development of the Patriot software to avoid the problems that led to the loss of life?

A. - The system should be well function for them to used it without any hassle and defect. They must also insure the system the has a good calculation of time.




3. What key lessons from this example of safety-critical software development could be applied to the development of business information system software?
