Which attribute refers to the extent to which outcomes can be seen?

• A. Relative advantage
• B. Observability
• C. Compatibility
• D. Complexity

Answer: (B)

Observability is the extent to which the outcomes of an innovation are visible to others. When the benefits are easy to see, staff and decision-makers can observe tangible improvements—like lower infection rates, better patient outcomes, or shorter hospital stays—which makes the value of adopting the change more obvious and speeds diffusion. This stands in contrast to other attributes: relative advantage is about whether the new approach is better overall, compatibility is about fit with values and workflows, and complexity concerns how hard the new method is to use. Because this option specifically captures how visible the results are, it best explains the question.
