ATS Implementation Checklist for HR Teams

An ATS implementation checklist helps HR teams plan, configure, test, launch, and maintain a new applicant tracking system. Use these steps to manage requirements, workflows, integrations, data migration, permissions, user training, and post-launch reviews.

Use this checklist when: implementing a new ATS, replacing an existing ATS, migrating candidate data, or upgrading recruitment workflows.

Who this is for: HR teams, recruitment managers, and people operations leads planning an ATS rollout or upgrade.

Value: Follow the checklist to achieve a documented plan, compliant configuration, reliable data migration, trained users, and consistent hiring workflows.

What Is ATS Implementation?

ATS implementation is the process of selecting, configuring, testing, launching, and maintaining an applicant tracking system for an organisation. It typically includes workflow configuration, user permissions, candidate data migration, integrations, testing, training, and post-launch support.
