Disadvantages of component based software engineering

Component Update: This activity ensures the updation of reusable components. Sometimes, updates are complicated due to inclusion of third party the organization that developed the reusable component may be outside the immediate control of the software engineering organization accessing the component currently.

Reusable: The components should be designed in a way that enables them to be used in different applications and different scenarios. This way, we can reduce cost and become much more productive since we will spend time only on customizing an already existing component.

Replaceable: Each component should be able to be replaced by a similar one in case it is no longer suitable, different functionality is required or the current component is obsolete. Lack of context specification: Components should lack context specification. This way, they can be integrated into different environments and contexts. Extensible: Each of the components can be further adjusted to provide additional functionality.

Encapsulation: Components hide their local details such as processes and variables and interact with each other through their interfaces. Independence: Each component should possess minimal dependencies related to others. This way we are sure that the system is not affected by the deployment of a particular component.

Disadvantages of Component Based Software Development As everything else, using component-based software development has its own disadvantages too. Together they form a unique fingerprint.

These prototypes are then tested to determine whether the product will work as designed and whether the product satisfies the key customer needs.

Later beta porotypes are extensively evaluated internally and are also typically tested by customers in their own use environment. This is usually to answer questions about performance and reliability in order to identify necessary engineering changes for the final product. Software Testing is also used to provide the objective and independent view of the system and that view allow to realize and understand the risks that could be faced at the implementation of the software. Multiple test techniques are included in the process of executing a program or application that has to be implemented with the intention of finding software bugs and errors.

Testing is the process of finding, detecting, or discovering errors. Testing plays a important role in assuring that we have achieved the required set of quality and…. Software engineering means implementing the concepts and principles of engineering to the Software development. There are different models in the software development process, all are developed based on software engineering.

Software engineering involves in the system requirements, system specifications, the design and architecture. It also involves in project management, quality control, testing techniques and tools at different….

The concerns that at the design or implementation phases are spread over several modular units crossing the limits of these units are named crosscutting-concerns. This crosscutting complicates the development activities, the evolution, and the maintenance of the software.
