Chapter 7 Software Development - Case Study

VIGNETTE “Boeing Dreamliner Faces A Few Bumps in the Road”

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?

Answer:

Yes, because not all software products are partially damage or have some defect. There are not 100% not damage.

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?

Answer:

It's better to insure all that the quality is high and good performance and meet the needs of the users. These are important factors on which customers make purchasing decisions.

Patriot Missile Failure

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?

Answer:

For me it's Yes by this part of overall effective testing and totally sealed to be as standard as compare top other missile.

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?

Answer:

I think ethically they do process and testing to avoid another incident happened that will kill another U.S armies. Through deploying their missiles is much effective like a radar that they use.

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

Answer:

Safety-critical software must review as soon as possible. It's because is often used to implement the functionality of safety systems because it can be designed to handle complex functionality, is accurate and repeatable, and can be cheaper than hardware solutions.
