Question

Why does usability engineering not necessarily guarantee usability for real people?

a.

It relies on measurements of very specific user actions.

b.

It does not provide a predictive design process for usability.

c.

It does not take into account the reasons behind specific usability metrics.

d.

It assumes the availability of specific features without understanding user needs.

Posted under Human Computer Interaction

Answer: (c).It does not take into account the reasons behind specific usability metrics. Explanation:Usability engineering may not guarantee usability for real people because it does not necessarily take into account the reasons behind specific usability metrics, such as the assumption that fewer explicit actions make the undo operation easier.
