Chapter 2, Problem 2.8E
Explanation of Solution
Prototype Systems:
A system prototype is used for carrying out the design experiments to check its feasibility.
Prototype systems should not be used as production systems in normal cases because of the following reasons:
- The production system is the final outcome but the prototype will show starting of the process.
- All the objectives of the production system cannot be fulfilled by same single prototype...

A new project has an average novelty for the software supplier that is going to execute it. Development flexibility is high, and requirements may change radically. The development team is all located at the same office and the software house as a whole tends to be formal in its standards and procedures. The product should be very reliable, and the algorithms are complex. The supplier would like to reuse the project with suitable modifications on further contracts. Developers are familiar with the platform and they are capable of conducting this specific type of project. The toolsets available to the development team are judged to be typical for this size of company, but schedule pressure is tight to meet a deadline.
A valuable team member is one who contributes meaningfully to the development of systems.Is it possible to guarantee that the developers and other designers on your team can implement your ideas with the aid of thorough documentation?
You have developed a prototype of a software system and your manager is very impressed by it. She proposes that it should be put into use as a production system, with new features added as required. This avoids the expense of system development and makes the system immediately useful. Write a short report for your manager explaining why prototype systems should not normally be used as production systems.

- A software development lifecycle is made up of several moving pieces. In what stage of the system's development do you think interacting with customers most effectively mitigates the risk of having to make frequent adjustments to meet fluctuating demand? Give an illustration to support your claim.arrow_forwardCindy Winslow liked her new job as lead systems analyst at Yorktown Industries. She was pleased that her development team completed the new human resources system ahead of schedule and under budget. Cindy looked forward to receiving the post-implementation evaluation because she was confident that both the system and the development team would receive high marks from users and manager. After the system operated for one month, Cindy received a call from her supervisor, Ted Haines. Ted told her that she would have to handle the evaluation, even though she headed the development effort. Cindy told Ted that she did not feel comfortable evaluating her own team’s work. She explained that someone who was not involved in its development should do an independent evaluation. Ted responded that he had full confidence in Cindy’s ability to be objective. He explained that no one else was available and he needed the evaluation quickly so he could move forward with the next stage in the corporate…arrow_forwardIn the process of designing a system, why would you find it necessary to use the concept of prototyping?arrow_forward
