Which type of testing is less intensive compared to full-scale and functional tests?

Tabletop testing is a type of testing that involves discussion-based sessions where stakeholders come together to simulate a response to a scenario without the need for physical execution. It is less intensive because it does not require extensive resources or setups, making it more of a conceptual exercise rather than a rigorous testing process. This method focuses on analyzing workflows, processes, and roles in a low-pressure environment to identify potential gaps or improvements in emergency response, incident management, or business continuity plans.

In contrast, full-scale and functional tests generally involve comprehensive and detailed operational or performance evaluations that require significant planning, execution, and often real-time conditions to assess system reliability and effectiveness. The nature of these tests is to rigorously validate that systems perform as expected under various conditions, which can make them much more resource-intensive and complex compared to tabletop testing.
