The FOSS-Powered Playbook for Remote Onboarding
New remote hires are often thrown into a digital void—given access to tools and a pile of documents, but no clear path. This fragmented, impersonal experience leads to isolation, slow ramp-up times, and a disconnect from your company's culture, increasing the risk of early turnover.
This playbook guides you in building a cost-effective, self-hosted onboarding system that fosters connection and clarity. By combining a structured knowledge base in Outline with a dedicated communication channel in Mattermost, you create a welcoming community for new hires. A simple Google Sheet orchestrates the process, ensuring every new team member has a clear path, a dedicated buddy, and feels like part of the team from day one.

- Dramatically reduce new hire isolation and foster a sense of belonging from day one.

- Embed company culture and unwritten norms through a community-driven process.
- Increase employee retention by building strong cross-functional relationships early.

The Workflow
Integration Logic
-
OnboardSync Bridge
This integration automates the employee onboarding workflow. When a new row representing a new hire is added to a designated Google Sheet, it triggers a sequence of actions. First, it uses the Mattermost API to create a new user account for the hire and adds them to a specific 'Onboarding' channel. Subsequently, it posts a customized welcome message in that channel, tagging the new user and including a direct link to their personal onboarding collection in Outline. Finally, it leverages the Outline API to create a new, personalized onboarding checklist page for the employee, typically cloned from a master template.
