What are the advantages and disadvantages of prototyping? Describe the steps in prototyping. Give at ...

Ans. to #1

Prototyping is most useful when there is some uncertainty about requirements or design solutions. Because prototyping encourages intense end-user involvement throughout the process, it is more likely to produce systems that fulfill user requirements. Working prototype systems can be developed very rapidly and inexpensively.
Rapid prototyping can gloss over essential steps in systems development. If the completed prototype works reasonably well, management may not see the need for reprogramming, redesigned, full documentation in testing to build a polished production system. This can backfire later with large quantities of data or large numbers of users in a production environment.
The steps in prototyping are:
1. identify the user's basic requirements,
2. develop an initial prototype,
3. use the prototype,
4. revise and enhance the prototype.
Prototyping might be especially useful in designing end-user interfaces, or situations in which the users have no clear ideas of what their information requirements are.

Ans. to #2

1. Systems lifecycle is a sequential step-by-step formal process, written specification and approvals, limited role of users.
2. In prototyping, requirements are specified dynamically with experimental systems in a rapid, informal, and iterative process; users continually interact with the prototype.
3. An applications software package is commercial software that eliminates the need for internally developed software programs.
4. In end-user development, systems are created by end users using fourth-generation software tools, rapid and informal, minimal role of information systems specialists.
5. In outsourcing, systems are built and sometimes operated by an external vendor.

The Internet allows anyone connected to it to communicate and compute at any time, or anywhere. Satellite systems, digital cell phones, and personal communications services will make it even easier to coordinate work and information in many parts of the globe that cannot be reached by existing ground-based systems. Companies can use Internet technology to construct virtual private networks to reduce wide-area networking costs and staffing requirements. If it wishes, the company can outsource the virtual private network to an Internet service provider.
All global systems can't be based primarily on the Internet because currently not all countries have the same access to the Internet. Additionally, high-traffic volumes at certain times of the day in various regions may impede responsiveness.

Oh god, I was lost before coming here. Thanksss

Great, make sure you mark the topic solved, it hides it from other eyes
