What is the Human Dependency Indicator (HDI)?

The Human Dependency Indicator (HDI) is a 0–100 score that measures how much an organisation's day-to-day operations depend on specific people, manual coordination and knowledge that exists only in someone's head. A low HDI means processes run on systems and documented rules; a high HDI means the operation quietly relies on a handful of individuals — and slows down, or stops, when they are unavailable. HDI was developed in pharma and life-sciences operations, where this kind of dependency carries regulatory and patient-impact risk, not just cost.

Unlike generic "digital maturity" scores, HDI measures a single, concrete thing: where work would break if the right person were away — and how many hours per month the organisation spends compensating for that dependency.

What does the HDI score mean?

HDI runs from 0 to 100, where higher means more human-dependent. The score maps to five bands:

• AI-Form (0–14). Processes are systemised and largely self-running. People supervise; systems execute.
• Managed (15–34). Documented processes with healthy backups. Dependency exists but is deliberate and controlled.
• Moderate (35–54). Noticeable reliance on key people and manual hand-offs. Growth will amplify it.
• High Risk (55–74). The operation depends on specific individuals in critical paths. Absences cause delays; scaling requires linear headcount growth.
• Critical (75–100). Systemic dependency on key operational nodes. A single unavailable person can stall regulated processes. Immediate intervention is warranted.

The score is not a grade of how "good" a team is. Strong teams often score high precisely because talented individuals are holding everything together personally — which is exactly the risk.

What are the three layers of HDI?

HDI breaks the overall score into three layers, because "dependency on people" hides three different mechanisms:

• Coordination dependency — how much day-to-day work moves only because people manually push it: approvals, hand-offs, status meetings, chasing. Measured by how tasks travel between people and what happens when a coordinator is away.
• Control dependency — how much problem detection and quality control lives in human vigilance rather than systems: who notices a deviation, how incidents surface, how long closure takes.
• Cognitive dependency — how much essential knowledge is undocumented: procedures people "just know", single experts for critical steps, onboarding that takes months because knowledge transfers only person-to-person.

The three layers matter because they call for different fixes. High coordination dependency points to workflow automation; high control dependency points to monitoring and alerting; high cognitive dependency points to knowledge capture and cross-training. One number would hide that.

What is the operational leak?

The operational leak is the number of working hours per month an organisation absorbs in manual coordination, hand-offs and compensating for dependency — expressed in hours and in full-time-equivalents (FTE). For example, a screening result of "≈1,100 hours/month ≈ 7 FTE" means the equivalent of seven full-time people's monthly capacity is being consumed by work that exists only because processes depend on people rather than systems. The free screening expresses the leak strictly in time, not money; converting it into financial terms is done in the full audit, on cost assumptions agreed with the client.

How is HDI measured?

HDI is measured in two phases. Phase 1 is a free 10-minute self-assessment: a structured questionnaire about how work actually moves through the organisation, plus a small set of industry-specific operational indicators. It produces the overall score, the three layers, a process-level heatmap and the operational leak in hours — a diagnosis of what is happening and where.

Phase 2 is the full audit. Its core is a structured workshop with the client's key people, run by an auditor against a calibrated instrument: every answer is scored against behavioural anchors, flagged patterns are recorded, and the client's Phase 1 self-assessment is triangulated against what the workshop reveals. Phase 2 explains why the dependency exists and what to do: decoded findings, prioritised automation entry points, the gap between leadership's picture and operational reality (the perception gap), cost quantification on agreed assumptions, and an implementation plan.

Who is HDI for?

HDI was built for operations in regulated life sciences: cell & gene therapy (CGT), ATMP manufacturing, CDMOs, conventional pharma, clinical research organisations and GDP-compliant medical logistics. In these environments human dependency is not an abstraction — it shows up as batch-record bottlenecks, deviation-closure delays, single-person release decisions and onboarding cycles measured in months. The methodology also applies to any operation that runs on approvals, hand-offs and expert knowledge; industry packs adapt the questions and benchmarks to each sector.
