This is a template I have used for an internship during my studies.
Its purpose is to track a consulting agency's projects, highlighting their different stages, as well as their financial impact.
Software used: Google Sheets (Microsoft Excel can work as an alternative, but since this dashboard is focused on the collaboration of consultants, Spreadsheets is best recommended).
Techniques used: Formulas (DATEDIF, IFS, SPARKLINE, IFERROR).
The "Darkboard" version shows the same information as the Dashboard, but its user interface is focused on reducing eye strain and battery consumption.
