“Boeing Dreamliner Faces A Few Bumps in the Road”
Questions
to Consider:
1.) Is
this example of software problems holding up the introduction of a major new
product and impacting a firm’s customers and suppliers unusual, or is it a
common occurrence?
Ans: Yes,
because not all software products is 100 percent totally not damage some have
defect.
2.) What
can organizations do to reduce the negative consequences of software
development problems in the production of their products and the operation of
their business processes and facilities?
Ans: In
order to reduce negative consequence of the software development, insure that
the quality is high and good performance. These are important factors on which
customers make purchasing decisions.
Patriot
Missile Failure
Discussion questions:
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? Do you think these steps would have improved the Patriot’s effectiveness enough to make it obvious that the missile was a strong deterrent against the Seud? Why or why not?
Ans: To prevent some problems the first steps could have been taking during development of the Patriot software is checked carefully to avoid in danger and serious problems.
2.) What
ethical decisions do you think the U.S. military made in choosing to deploy the
Patriot missile to Israel and Saudi Arabia and in reporting the effectiveness
of the Patriot system?
Ans: The U.S. military made in
choosing to deploy the Patriot Missile to Israel and Saudi Arabia because in
the desert they have a field area and far in accident.
3.) What
key lessons from this example of safety-critical software development could be
applied to the development of business information system software?
Ans: There are many reasons why
safety is very important. For example, how would you demonstrate that a system
was absolutely safe? Even if it continued to operate without any threat to
safety for several years, there may be no guarantee that it will not fail in
the next 24 hours. Changes in the environment, hardware failures, untested
modes in software systems can all work together to expose systems in ways that
had not been done in a previous period of safe operation.
