You are the business analyst for your organization and are working on a solution that will connect several databases to a web application. You are concerned that the databases may not be operable…

Benchmarking compares an organization's processes or performance against industry peers or best practices, and does not assess the technical compatibility between software components.

Interviews gather stakeholder knowledge and perspectives verbally but cannot reveal the technical data formats, protocols, or integration constraints that determine system interoperability.

Interface analysis examines the boundaries between systems - including data formats, communication protocols, APIs, and integration points - to determine how they exchange information and whether they are compatible. By applying this technique, the business analyst can identify whether the recommended software solution can successfully communicate with the existing databases and web application, revealing any interoperability gaps. It is the elicitation technique directly purpose-built for discovering integration and compatibility requirements between disparate systems.

Usage considerations or usage scenarios describe how end users interact with a system from a behavioral perspective and do not address the underlying technical interoperability between software, databases, and web applications.
