Component-based software is a promising tecnology for increasing developer productivity and software quality. The promises of component-based software engineering are cost reduction and increased quality through reuse of proven components, as well as better maintainability through flexible software architectures.

Possible pitfalls for establishing component-based software engineering are performance issues, security, safety, trust in third-party components, and configuration management of complex componentized.

Besides various technological deficiencies, there are many decisions to take such as:
 

• Which component architecture to take?
• Which components are most appropriate?
• Which infrastructure/middleware is needed to develop, deploy, and maintain component-based software systems?
• How to develop components, if no reusable components are available?
• ...
