considering processing speed, response time, resource consumption, throughput, and efficiency

Effective interfaces are visually apparent and forgiving, instilling in their users a sense of control. Users quickly see the breadth of their options, grasp how to achieve their goals, and do their work.

A well-designed WebApp interface provides “the illusion that users are in the same place, with the work brought to them.”

the interface “look and feel” coupled with supporting information that describe interface syntax and semantics

A WebApp interface should be designed to minimize learning time, and once learned, to minimize relearning required when the WebApp is revisited.

the amount of time required for a person to move a pointer (e.g., mouse cursor) to a target area is a function of the distance to the target divided by the size of the target. Thus, the longer the distance and the smaller the target’s size, the longer it takes.

The WebApp should use multi-tasking in a way that lets the user proceed with work as if the operation has been completed.
