Challenges of component-based development paper

In this paper the authors discuss the issues and challenges encountered when developing and using an evolving component-based software system.

The authors presents the ABB Advant control systems (OCS) as a successful example of the development of component-based system.

Different reuse challenges

Component generality and efficiency Sufficiently general to cover the different

aspects of their use. Concrete and simple enough to serve a

particular requirement in an efficient way.

Different reuse challenges

System evolution Long-life products are most often affected by

evolution of different kinds: Evolution of system requirements, functional and non-

functional. Evolution of technology related to different domains. Evolution of technology used in software products. Evolution of technology used for the product

development. Evolution of society. Business changes. Organizational changes.

Different reuse challenges

Evolution of functional requirements

Different reuse challenges

Migration between different platforms Compatibility Development environment

Support for development of components on different platforms.

Support for development of different variants of components for different products.

Support for development and maintenance of different versions of components for different product versions.

Independent development of components and products.

Different reuse challenges

Independent component development Advantages

The functions are broken down into smaller entities that are easier to construct, develop and maintain.

Problems The component and product test become more

difficult. Integration and configuration.

Different reuse challenges

The maintenance process System level Product level Component level

Risks and Challenges of component-based development paper

Influenced by the literature, that does not clearly identify the risks for the various CBSD stakeholders, in this paper the author identifies key CBSD risks and challenges encountered by each category of stakeholder.

Stakeholders

Component developers Application assemblers Customers

Component Developers

Encounters certain risks and challenges in developing components, managing component-development projects, and subsequently marketing the components.

Generally fabricate components under two scenarios: Survey the overall software industry and build

components for the mass market; Develop components for a specific client or

assembler.

Component Developers

Challenges and risks Identify business areas or domains that would generate

enough yield to justify component development. Component repositories become obsolete due to poor

planning or unfavorable industry trends. Well-defined interfaces specifying how components work,

along with their inputs, outputs, and exception-handling procedures.

Choose suitable methodologies and tools for constructing components.

Quality of the component that requires a comprehensive testing program.

Application Assemblers

Risks and challenges primarily concern the assembly of components in applications, the management of component-based application assembly projects, and the uncertainties of the component market.

Application Assemblers

Challenges and risks Matching system requirement

specifications. Demarcating the requirements document

into smaller subsets. Confirming the overall selected

component set. Having to depend on a developer offering

components in the mass market.

Customers

Face both risks and challenges in using component-based applications to meet their enterprise requirements, as well as in managing their component-based and legacy application systems and in achieving and sustaining strategic competitive advantage over their rivals.

Customers

Challenges and risks Whether a system is actually capable of

satisfying customer requirements. Application quality based on component

quality. New component-based applications not

interoperating with their existing legacy software.

Stakeholder risks and challenges

Key CBSD stakeholder risks and challenges and their cascading effects

Conclusion

Development component-based system envolve risks and challenges.

The new paradigm in the development process and marketing strategy has introduced new problems and raised new questions.
