A dashboard can be thought of as an executive information system designed so users can easily comprehend and interpret the impact of business data on an organization. Dashboards provide quick insight into an organization's Key Performance Indicators (KPIs) that represent defined company objectives or business processes such as sales, marketing, human resources, and production. They help users rapidly understand whether their company is performing well or not. Nevertheless there are limitations since dashboards usually show summaries, key trends, and exceptions but do not present the details.
Though they are both data visualization tools that display the status of metrics and KPIs, the terms "scorecard" and "dashboard" are not interchangable. Scorecards are more qualitative in nature and rely on internal and external benchmarks to help achieve individual and corporate goals and objectives. Dashboards are more quantitative - they're all about numbers, charts and graphs that are easy to understand at a glance.
