15.10 Glossary of Terms

  1. Analytical Dashboard: A dashboard designed for historical analysis and trend exploration, featuring interactive elements that allow users to filter, drill down, and compare data across dimensions.

  2. Balanced Scorecard: A strategic planning and management framework developed by Kaplan and Norton that organizes performance metrics across four perspectives: financial, customer, internal process, and learning and growth (Kaplan and Norton 1996).

  3. Dashboard: A visual display of the most important information needed to achieve one or more objectives, consolidated and arranged on a single screen so it can be monitored at a glance (Few 2006).

  4. Decision Support System: A computer-based information system that presents relevant data, models, and analysis to assist — but not replace — human decision-making.

  5. Drill-Down: The ability to navigate from a summary view to increasingly detailed data by clicking or selecting elements in a dashboard, enabling progressive exploration.

  6. flexdashboard: An R package that enables the creation of dashboards using R Markdown syntax, producing self-contained HTML output with support for value boxes, gauges, and multi-panel layouts (Iannone et al. 2024).

  7. Gauge: A visual dashboard element that displays a single metric relative to a defined range, often using a dial or arc metaphor with colored sectors indicating performance zones.

  8. Information Hierarchy: The arrangement of dashboard elements by importance, with the most critical information placed in the most prominent position — typically the upper-left quadrant.

  9. Key Performance Indicator (KPI): A measurable value that demonstrates how effectively an organization is achieving a key business objective. Effective KPIs meet the SMART criteria: Specific, Measurable, Actionable, Relevant, and Time-bound (see also Chapter 13 for KPIs in requirements specifications).

  10. Operational Dashboard: A dashboard designed for real-time or near-real-time monitoring of day-to-day operations, used by front-line managers who need to respond quickly to changing conditions.

  11. Progressive Disclosure: A design pattern that shows summary information at the top level and allows users to access increasingly detailed data on demand, reducing visual clutter while preserving access to detail.

  12. Quarto Dashboard: A dashboard format built on the Quarto publishing system, serving as the modern successor to flexdashboard with support for multiple programming languages and improved layout controls.

  13. Shiny: An R package for building interactive web applications that enables server-side reactivity — user inputs dynamically update the dashboard display in real time (Chang et al. 2024).

  14. Sparkline: A small, inline chart — typically a line graph — embedded within a dashboard panel or alongside a value box to show trends without consuming significant screen space.

  15. Static Report: A fixed document (PDF, HTML, or printed) generated at a specific point in time, presenting analysis results in a linear, narrative format suitable for archiving, compliance, or broad distribution.

  16. Strategic Dashboard: A high-level dashboard that tracks organization-wide KPIs aligned with long-term goals and targets, designed for executive leadership who need periodic performance summaries.

  17. Value Box: A dashboard component that prominently displays a single metric with an optional icon and color coding to indicate status, designed for at-a-glance KPI monitoring.

  18. Visual Information Seeking Mantra: Shneiderman’s principle for designing interactive visualizations: “Overview first, zoom and filter, then details on demand” — the foundation of progressive disclosure in dashboard design (Heer and Shneiderman 2012).
