# Design Disciplines
Consistency
Feedback
Efficiency
Controllability
## Consistency
- **Consistent with real life:** in line with the process and logic of real life,
and comply with languages and habits that the users are used to.
- **Consistent within interface:** all elements should be consistent, such as:
design style, icons and texts, position of elements, etc.
## Feedback
- **Operation feedback:** enable the users to clearly perceive their operations
by style updates and interactive effects.
- **Visual feedback:** reflect current state by updating or
rearranging elements of the page.
## Efficiency
- **Simplify the process:** keep operating process simple and intuitive.
- **Definite and clear:** enunciate your intentions clearly so
that the users can quickly understand and make decisions.
- **Easy to identify:** the interface should be straightforward,
which helps the users to identify and frees them from memorizing and recalling.
## Controllability
- **Decision making:** giving advice about operations is acceptable, but do not
make decisions for the users.
- **Controlled consequences:** users should be granted the freedom to operate,
including canceling, aborting or terminating current operation.
