## Use this to eliminate, not crown

Start with a real localization leaders and product teams selecting a translation management system workflow. Eliminate candidates that fail a deployment, format, locale, accessibility, or exit requirement; then test the survivors with your own content.

- Write three non-negotiable gates before opening the table.
- Choose the view that matches the decision in front of you.
- Open the linked documentation for any field that changes the shortlist.
- Run one representative import, production, review, and export cycle.

## Proof-of-work protocol



```
1. Import a representative source with placeholders, markup, plurals, and right-to-left text.
2. Route it through translation, review, QA, and correction.
3. Exercise automation or integration under realistic permissions.
4. Export every asset and target file needed to leave.
5. Record defects, manual steps, plan dependencies, and owner responses.
```

## Frequently asked questions

### Which TMS is best?

There is no context-free winner. The decisive differences usually appear in the real repository or connector path, reviewer experience, supported source formats, permission model, linguistic-asset handling, and the completeness of an exit export.

### What should a TMS proof of concept include?

Use one representative release: import difficult source content, run translation and review, exercise automation with production-like permissions, fix a defect, and export targets, TM, terminology, comments, and any history you must retain.

### Does self-hosting guarantee data control?

No. Data can still leave through MT or AI providers, connectors, logging, backups, support access, or misconfiguration. Map those flows and test the deployed configuration.

## Methodology

Admas reviewed current first-party product documentation against criteria specific to this tool category. A missing claim is recorded as not established, not scored as a failure. Entries describe documented product capabilities, not plan entitlement, implementation quality, security posture, or suitability for a particular organization. Re-run the proposed proof-of-work and export test before procurement.
