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:
Mismanaged soft-ware can now be fatal to a business, causing it to miss product delivery dates, incur increased product development costs, and deliver products that have poor quality.
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:
A software companies should adopt a software development methodology —a standard, proven work process that enables systems analysts, programmers, project managers, and others to make controlled and orderly progress in developing high-quality software. A methodology defines activities in the software development process, and the individual and group responsibilities for accomplishing these activities. It also recommends specific techniques for accomplishing the various activities, such as using a flowchart to document the logic of a computer program. A methodology offers guidelines for managing the quality of software during the various stages of development. If an organization has developed such a methodology, it is applied to any software development that the company undertakes.
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 Scud? Why or why not?
Answer:
The steps could have been taken during development of the Patriot software is checking the accurate of its time calculation while using the systems and all offices or areas, and improve its tracking function to detect every missile/scud coming.
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:
To make sure that the patriot system should have good benefits for all and it should be well function, like its system function, time calculation for every scud coming, and over all checking system function time to time in all areas using it.
3. What key lessons from this example of safety-critical software development could be applied to the development of business information system software?
Answer:
Key lessons, is to make sure that all system functions is well develop before using it or implement it to the some offices. The system developer and client should always try the system from its time to time development.
