Explanation / Answer

4.1.3

Phases of prototyping model

4.2.1

Advantages of component based model

Reusibility:

The components should be designed in a way that enables them to be used in different applications and different scenarios. This saves a lot of cost and is much more productive since time has to be spent only on customizing an already existing component.

Replacability:

Each component should be able to be replaced by a similar one, thus if slightly different functionality is required or the current component is obsolete or no longer suitable, it can be quickly substituted.

Lack of context specification

The components need to be designed to be integrated into different environments and contexts.

Extensibility:

Each of the components can be further adjusted to provide additional functionality.

Encapsulation:

The components can interact using only their interfaces, therefore hiding the local details such as state, processes or variables.

Independence:

The components should be appropriate for deployment into any suitable environments, thus they should possess minimal dependencies related to other components. This ensures that the deployment of a particular component do not affect the whole system in any way.
