Common mistakes that break translation workflow outcomes
Translation projects fail when tool capabilities are mismatched to workflow state management. Many issues come from underestimating setup complexity for automation or governance, or from assuming all tools support the same exchange and collaboration patterns.
The list below calls out concrete pitfalls tied to how each tool is built to work in a pipeline.
Assuming MT post-editing can be treated like TM-only editing without extra process steps
MateCat adds MT post-editing setup overhead versus pure TM-based work, so teams should plan process time for post-editing orchestration inside the editor.
Underestimating workflow configuration time before automation becomes efficient
Transifex requires time to configure workflow rules, so automation often stays brittle until file rules and endpoints are aligned with each release format.
Routing governed MT work without establishing disciplined approval and routing setup
Unbabel workflow setup requires governance discipline to avoid routing errors, and insufficient routing definitions can break traceability even when MT quality is strong.
Overlooking that desktop automation can depend on add-ons rather than a single built-in orchestration view
Trados Studio relies on add-ons and integrations for workflow automation, so automation plans should not assume one native orchestration screen covers every lifecycle step.
Expecting a web TMS to replace local desktop collaboration patterns
OmegaT has no native web-based collaboration for concurrent human review, so teams that need shared in-browser review should select a workflow-driven cloud tool like Crowdin or Unbabel.
