Profiles describe relevant features of a person without reducing the person to a single rank. They can include developed capacities, current availability, needs, responsibilities, preferences and the supports through which functioning is organized. Their content should be determined by a defined question rather than by an unrestricted attempt to capture the whole person.

A profile is useful when it helps distinguish what the person can contribute, what is currently accessible and what the surrounding configuration must provide. It should remain revisable as capacities, conditions and purposes change.

Assessments examine a defined situation or decision. They connect the profile of the person with environmental demands, supports, constraints, consequences and possible interventions. The purpose may be to understand present functioning, identify a mismatch, evaluate support or determine what evidence a performance can provide.

Validity depends on the question being asked. An assessment designed to identify independent retained knowledge is different from one designed to determine whether a person can participate effectively with appropriate support.

Indexes move the unit of analysis beyond the individual. They can show how a workplace, service, technology, policy or country requires, supports, develops, distributes or consumes human capacity. This makes visible effects that conventional institutional metrics often omit.

An organization may improve efficiency while transferring coordination to users, or increase output while concentrating fatigue and recovery costs in workers. Index design should identify whose capacity is affected, through which mechanism and over what period.

Standards translate validated knowledge into expectations for institutional design and practice. They may concern accessibility, demand, support, evidence, attribution, agency, reassessment or remedy. Standards should not freeze provisional research or assume that one configuration is appropriate for every person and context.

The sequence matters: concepts require operationalization, measures require validation and normative requirements require transparent justification and stakeholder scrutiny. The Initiative’s standards work is therefore developmental rather than a claim that a complete accredited system already exists.

The four layers become useful when their definitions, units, evidence and limitations are explicit. Registries, shared measures, linked datasets and reproducible methods can allow findings to accumulate across disciplines while preserving the distinctions among capacity, context, performance and outcome.

The goal is not measurement for its own sake. It is to support better decisions without making claims about people or institutions that the available evidence cannot sustain.
