Which analysis technique identifies interfaces and interactions between solutions or solution components?

The analysis technique that focuses on identifying interfaces and interactions between solutions or solution components is interface analysis. This technique is crucial in understanding how different elements of a system communicate and interact with one another. By examining the points of connection, interface analysis helps to clarify the roles and responsibilities of each component and ensures that there is coherence in how solutions integrate with each other.

Interface analysis is particularly important in complex systems where multiple components need to work together seamlessly. It helps stakeholders understand potential dependencies, data exchanges, and the overall flow of information, which is essential for effective system design and ensuring that user needs are met without conflicts between different system parts.

In contrast, process analysis primarily looks at the workflows and procedures within a system rather than the interactions between components. Requirement analysis focuses on gathering and defining the needs of stakeholders and does not specifically address the interfaces themselves. Impact analysis assesses the potential effects of changes within the system but does not concentrate on the identification of interfaces. Thus, interface analysis is the most fitting choice for identifying the interactions between solutions or solution components.
