Overview
ISO/TS 30425:2021 - "Human resource management - Workforce availability metrics cluster" provides a standardized approach for measuring workforce availability. The technical specification defines measurement elements, formulas and reporting guidance to produce comparable internal and external metrics. It focuses on working capacity of permanent and temporary staff (not on allocated tasks, skills or suitability, which ISO 30409 covers) and explains interpretation issues when reporting to stakeholders such as regulators, investors and boards.
Key topics and requirements
- Core metrics covered
- Headcount: point-in-time count of people employed (includes full‑time, part‑time and zero‑hour employees).
- Full‑time equivalent (FTE): converts part‑time hours into equivalent full‑time employees using the formula D = A + (B/C) where A = full‑time employees, B = part‑time total hours, C = average weekly working hours.
- Contingent workforce: measurement of independent contractors and temporary or leased workers to capture effort and hours.
- Absenteeism: standardized approach to track and interpret absence data (including contextual and predictive factors).
- Measurement practice
- Align measurement points with the financial year or budgeting cycle; calculate at defined period ends (e.g., month, quarter, year).
- Maintain consistency and document chosen measurement points.
- Report comparisons over time (typical 3–5 year comparison) and compare actual vs budgeted figures.
- Interpretation & reporting
- Guidance on contextual factors and issues to consider when interpreting compliance data.
- Recommendations for granular reporting (team, department, location, organization) and aggregation for overall workforce availability insight.
Applications
- Workforce planning and capacity modelling
- HR analytics and people‑metrics dashboards
- Budget vs actual workforce reconciliation
- Contingent labour management and cost/effort comparisons
- Absence management interventions and predictive analysis
- External reporting to regulators, investors and governance bodies using comparable metrics
Who should use this standard
- HR professionals, people analytics teams and workforce planners
- HR leaders, CFOs and operational managers responsible for capacity planning
- Compliance officers and reporting teams preparing external disclosures
- Consultants and auditors benchmarking workforce availability across organizations
