Information dashboards aim to augment human cognitive abilities and aid in decision-making. Often users assume that it is enough to rely on the analytics provided separately by various business intelligence software or tools.
A good dashboard has a well thought out User Interface leading to a quality User Experience with the objective of providing an effective Business Value. Donald Norman, a computer scientist and researcher says "Two of the most important characteristics of good design are discoverability and understanding".
Since recognition memory is superior to absolute recall, the dashboard should provide all the information that a user needs for a specific analysis. By providing the end user with fewer, but thoughtful options, we are providing the user with a simpler experience and offering some best practices.
