The article discusses a new method for creating adaptable software components using top-down analysis. This approach aims to improve the quality of reusable components in software development. By analyzing the domain of an application, functional and data components are identified for potential reuse. The study shows that using top-down analysis can lead to better quality components. This method tailors strategies and models specifically for each domain, ensuring the components are suitable for their intended use. By focusing on domain analysis, developers can build more effective and efficient reusable software components.
