Designers use dashboards to represent raw data in a visual form that is helpful and supports immediate recognition and extraction of information that is most important.
The purpose of dashboards is to help users gain an understanding of what is going on within the area of their interest and how it relates to them. As such dashboards should be made to help save the intended audience from
- having to work through large amounts of data
- carry out calculations
- carry out other time consuming operations
Without this every individual user is forced to investigate the raw data themselves
this is more
- time consuming
- error prone
The reasons dashboards should be employed are that they are a more efficient alternative compared to using the raw data (quantitative and qualitative) that is derived form research. The better the design, the better the understanding of the information.
