The Employee Capacity Survey.
Thrive measures capacity with an assessment — a structured, statement-level instrument, not a wellness check-in or a single self-rated score. Its 55 validated, behavior-anchored statements score four capacity domains (Energy, Recovery, Focus, Resilience) alongside four engagement domains, anonymously, in about 12 minutes per employee. Each person sees their own private result, and the findings lead to action plans and matched learning.
Why an assessment.
Capacity could, in principle, be inferred from wearables or biometric data. At organization scale, though, a validated, behavior-anchored assessment is the practical way to measure it consistently, anonymously and across every role, without new hardware or consent friction. The assessment is informed by biomarker and physiological research without collecting biomarker data, and its statements are research-grounded, not ad hoc — drawn from an underlying evidence base of peer-reviewed literature per domain.
Statement design, cadence and reporting thresholds: how to measure employee capacity.
The measurement cycle.
Measuring capacity isn’t a one-off exercise — the assessment runs as a repeating cycle: employees are invited, they answer anonymously, responses are scored into domain and index results, and those results route into action — for managers, for HR, and for the employee’s own learning.
Invite, answer, score, act — walked through step by step in How it works.
How it’s scored.
Each statement response rolls up into one of four capacity domains, each scored 0–100. The four domain scores combine into a single Capacity Index, which is then measured alongside the Engagement Index to place each result on the Thrive Matrix.
Cadence & tracking.
Capacity is measured on a recurring cycle — typically quarterly — specifically because it is designed to move. Employees and organizations see their scores change from one assessment to the next, which is what makes capacity an actionable metric rather than a one-time snapshot.
The assessment described here runs inside the wider assessment platform, which routes results into action plans and matched learning.
Method & sources.
This page describes the measurement method behind the Capacity Index: 55 statement-level items across four domains, anonymous, roughly 12 minutes to complete, scored 0–100 per domain and combined into an index.
Statements are grounded in peer-reviewed literature per domain; the underlying evidence base and validation study are documented separately.
