Although heuristic Usability heuristics can uncover many major usability issues in a short period of time, a criticism that is often leveled is that results are highly influenced by the knowledge of the expert reviewer s.

Once there is a benchmark, other designs can be compared to it to determine the usability of the system. Allow users to tailor frequent actions. This will decrease information search time.
