Interview is most flexible and direct tool for eliciting requirements. It also more prone to misunderstanding and failure than any other technique. Early interviews in the requirements gathering process have a broad scope, while the later ones are defined by more focus on detail. Interviews fall between two extremes: structured, where we can control the flow, and focused, where we must go deeper with the flow. Since interviews are a finite and expensive resource, they must be planned carefully in advance to derive maximum benefit.
Questionnaires are the second choice for requirements elicitation and the first choice for requirements verification. The structure of questionnaires as elicitation tools are generally the same as in interviews, but the flow is inflexible. As a verification tool, questionnaires are the most traceable.
Elicitation workshops are the most powerful, but also the most expensive tool for requirements elicitation. Since they are very expensive, you must select participants carefully and help them to help the workshop.
Field trips and observation provide valuable requirements where workflow is rich in action and interaction. But you must be aware that the value of observing a workflow also depends on the goal of the observation.
Models can be used to verify requirements. These models need not be formal blueprints for the construction of the system, but can be any drawing or word chart that the stakeholders can understand. Mock-ups are one such modeling technique; they are approximations of the system's user interface to elicit comments and requirements.

The Web was invented between 1989 and 1991 when Dr. Tim Berners-Lee and his associates at CERN Laboratories built on the ideas of several earlier researchers and developed the initial versions of HTML, HTTP, a web server, and a web browser, the four essential components of the Web. Information being shared on the Web remained text-based until Marc Andreessen and others at NCSA (National Center for Supercomputing Applications) created a web browser with a graphical user interface. This made it possible to view documents on the Web that included colored backgrounds, images, and primitive animations. In 1994 Andreessen and Jim Clark founded Netscape, which created the first commercial browser. In 1995 Microsoft released the first version of Internet Explorer and the Web began to take off.

Answer 16

There are four approaches to reuse: ad-hoc, facilitated, managed, and designed. The ad hoc approach to reuse is not really an approach at all. With this approach, individuals are free to find or develop reusable assets on their own, and there are few, if any, organizational rewards for reusing assets. With facilitated reuse developers are not required to practice reuse, but they are encouraged to do so. The organization makes available some tools and techniques that enable the development and sharing of reusable assets, and one or more employees may be assigned the role of evangelist to publicize and promote the program. With managed reuse, the development, sharing, and adoption of reusable assets is mandated The most expensive and extensive approach to reuse is designed reuse.

A software application is a dynamic entity. Consequently, its usability depends on how well it flows and how successfully it can control and direct its building blocks toward goals that the application must help its users to achieve. Objects that control the flow of the application, direct the sequencing of events, manage the interaction among objects, and encapsulate the behavior specified by use cases are called control objects.
