• One controlled specification per raw material, intermediate and finished product.
• Versions with approval, effective dates and a record of who changed what.
• Test methods and limits linked to the specification, not copied into each certificate.
• Supplier specifications compared against your own, with differences flagged.
• Customer specifications held against the products you supply them.
• Incoming results checked against the current specification automatically.
• Changes that show every product, formula and customer affected before approval.
• Specifications that feed certificates of analysis and batch release directly.

A spec in a PDF can't tell you which formulas use the material, which suppliers are approved against it, or which customer agreements quote it. So a tightened limit is often discovered at goods-in, or by a customer.

Specs are data: parameters, limits, methods and versions. Changes go through approval with a clear view of what's affected, and quality checks use the current limits automatically.

Worldover links each specification to the material, its suppliers, the formulas using it and the tests that release it. When a supplier proposes a change, Willow shows the formulas and customers affected and drafts the review for a person to approve.

A cosmetics brand tells its ingredient supplier that the heavy metals limit for an emollient is tightening from 10 ppm to 5 ppm. The technical manager opens the customer specification, updates the limit and sees immediately that the last six batches all tested below 5 ppm, but one raw material supplier's own specification allows up to 8 ppm.

The change is approved with an effective date. From then on, incoming lots from that supplier are checked against the new limit, and the certificate of analysis for this customer shows the tighter value. Willow drafts a note to the supplier asking whether they can commit to the new limit, for the buyer to review and send.

Most teams begin with specifications scattered across Word files, spreadsheets and supplier PDFs. Bringing them into one controlled record is the first job, and Willow can help extract limits from existing documents for a person to check.

Worldover manages specifications for chemicals and cosmetics companies. It isn't a laboratory instrument system, although results from your lab can be brought in to check against specification.
