Completed more rapidly than systems developed with conventional tools.
The disadvantages of end-user development are cannot handle large numbers of transactions, extensive procedural logic. Often lead to higher level of user involvement and satisfaction with system.

1. scope- The project's scope defines its boundaries. If the project represents an engineering design, for example, the scope will identify the features and functionality that must be included.
2.time- Actual process has to match planned progress.
3. cost- the project must be completed without exceeding authorized expenditure
4. Quality-the end result of a project must fit the purpose for which it was intended.

can directly

produce functional parts in small production quantities.

Parts produced in this way usually have an accuracy and surface finish inferior to those

made by machining.The disadvantages of prototyping are that it may not be suitable for large sized applications.

The producer may produce an inadequate system that is unable to meet the overall demands of the organization. Too much involvement of the user might hamper the optimization of the program.

Question 2        The user experience for mobile device interaction is fundamentally different from using a desktop or laptop PC. Saving resources, bandwidth, screen space, memory, processing, data entry, and user gestures are top priorities for mobile app design. Rather than designing three different Web sites for three different types of computing devices, responsive Web design allows developers to design one Web site that automatically changes layouts according to the user’s screen resolution, whether on a desktop, tablet or smartphone.

Formal review at the end of each phase allows maximum management control. This approach creates considerable system documentation. creates considerable system documentation. The disadvantage are major problem - end-user does not see the solution until the system is nearly complete. Users get a system that meets the need as understood by the developers; this may noy be what was really needed.
