# Product Data Stewardship

> The operational role of maintaining product data to agreed standards day to day, applying governance rules, resolving exceptions and monitoring quality.

## Definition

The operational discipline of maintaining product data to the standards that governance has set.
Stewards apply agreed rules, create and maintain records, resolve exceptions and conflicts between
sources, monitor quality against defined measures, and escalate issues that require a governance
decision.

## Expanded Explanation

Stewardship is where governance meets daily work. A steward is typically embedded in the function
that produces the data rather than in a central technology team, because judgement about whether a
composition value is plausible belongs with the people who understand the product. Stewardship is a
role rather than a job title; in many organisations it is a defined portion of an existing role.

Typical responsibilities include onboarding new products to the agreed standard, reviewing values
that fail validation, arbitrating between systems that disagree, chasing missing supplier
declarations, maintaining reference lists and classifications, and reporting quality trends to the
governance forum.

The distinction from governance matters. Governance decides who is authoritative for recycled
content and what approval a change requires. Stewardship makes sure the value is actually present,
plausible, current and approved for the products being published this month. Neither works without
the other.

## Why It Matters

Passport obligations are continuous rather than one-off. Products change specification, suppliers
change, and published information must remain accurate for as long as the obligation lasts. Without
named stewards, quality achieved during a launch project decays quietly until a market surveillance
enquiry or a customer complaint reveals it.

## Common Misconceptions

#### Stewardship is data entry

Entry is a small part of it. The substantive work is judgement: deciding which conflicting value
is correct, whether evidence is adequate, and when to escalate.

#### A central team can steward all product data

Central teams can coordinate and measure, but the domain knowledge needed to judge specification,
composition and conformity data sits in the originating functions.
