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...

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 key team member should be named in system development.
Is it feasible for the engineers and other designers on your team to
implement your ideas with the aid of sufficient documentation?
The standard Software Development Life Cycle (SDLC) has been around for a long time and has been utilized effectively for many system development projects. This is why it is referred to be "traditional." There are, however, certain downsides to this option. What are the pros and cons of using the SDLC approach?

- You and your team have been hired to perform a system investigation for a fast food restaurant that wants to implement new tools and processes to improve its customer service. Currently, the restaurant has a poor reputation for not correctly filling customers orders and for taking too long to do it. Perform a functional decomposition to define the scope and basic requirements of such a system. Brainstorm some ideas to improve the situation, and choose one to pursue based on its technical, economic, legal, operational, and schedule feasibility.arrow_forwardAn organization has selected and is now implementing a software package. Identify three key factors that will determine the cost and time required for implementation.arrow_forwardThe CRUD approach should be described and explained. What is it actually, and how does it connect to use cases? The Software Development Life Cycle (SDLC) is divided into six major stages.arrow_forward

At what stage do you think incorporating feedback from customers will help the system mature with little changes to demand? Provide an illustration to back up your claim.arrow_forward
- Congratulations! Your team has been selected from a pool of numerous competitors, to take over the software development project for a complex electronic system to be used by many organizations around the globe. The current team has made a good start on the project, up to and including a Preliminary Design Review. There is a significant bonus available, if your team can take over the project and complete it ahead of schedule! The only catch is that the current team is soon to be relocating to Antarctica, will no longer be reachable, and will be taking all of their stuff with them. So your team needs to request whatever they need in before the current team's departure. Also, there are severe penalties and consequences should things not go well. :-( Initial Post: Prior to the departure of the current team • What details do you need? Why?
