HR generates as much data as finance: headcount, recruiting, payroll, training, performance, engagement. Apache Superset is an open source alternative to proprietary tools (Tableau, Power BI) for steering this function. This guide details essential dashboards and KPIs for 2026.
1. Why Superset for HR?
- Data sensitivity: strict GDPR, EU hosting often mandatory;
- Multi-source: HRIS, payroll, ATS, training, surveys;
- Segmented dashboards by manager / department;
- Cost: HR Tableau licenses quickly cost several thousand €/year.
If you want an HR-ready instance, TVL Managed Superset is hosted in France and GDPR-compliant.
2. HR data sources
- HRIS: BambooHR, Lucca, PayFit, ADP, Workday;
- ATS: Greenhouse, Lever, Welcome to the Jungle;
- Payroll: Sage, ADP, Silae;
- Engagement: Officevibe, Glint, Culture Amp;
- Training: 360Learning, Workleap.
3. Dashboard 1 — Headcount overview
- Total FTE and monthly evolution;
- Distribution by department / country / function;
- Age and tenure pyramid;
- Manager / IC ratio;
- FTE / revenue if relevant.
4. Dashboard 2 — Recruiting
- Candidate pipeline by stage;
- Average time to hire;
- Cost per hire;
- Source of hire (LinkedIn, referrals, jobboards);
- Conversion by stage (apply → interview → offer → accept).
5. Dashboard 3 — Turnover and retention
- Annual turnover rate, global and per segment;
- Regrettable vs non-regrettable turnover;
- Median tenure per function;
- Hire cohorts and their 12/24-month retention;

This configuration is applied by default on TVL Managed Superset, which follows community best practices.
6. Dashboard 4 — Engagement and wellbeing
- eNPS (Employee Net Promoter Score);
- Pulse survey response rate;
- Engagement score evolution per department;
- Top 5 qualitative feedbacks;
- Flagged attrition risks.
7. Dashboard 5 — Diversity and inclusion

9. Security and GDPR
