Before Glean reaches every employee, connect the sources people search most and fix sharing. Pilot a few hundred users on seeded content. Set usage limits before company-wide seats.
When you need this
- A Glean contract is signed or close, and IT owns the first rollout wave.
- Employees search Slack, Drive, Confluence, and the CRM one at a time, and questions land on the same few colleagues.
- A first wave launched, and usage is flat or concentrated in a few people.
Evaluation criteria
Setup: connect the sources that answer most questions
Which five to ten apps hold most of what employees ask about?
Look forConnect those sources first. Check crawl status and rate, plus items synced, in the Admin console. Crawl time depends on content volume and each source's API rate limits.
Governance: sharing audited before launch
What would an employee find today in your most broadly shared folders and channels?
Look forSet inclusion and exclusion rules per connector. Review a one-time sensitive-content report. Fix missing department and manager fields, which reduce relevance and break the org chart. SSO is mandatory for Glean and is the first thing configured for a new Glean environment.
Rollout: a pilot of 100 to 300 users
Does the first wave span several departments, with a way to collect feedback?
Look forRecruit pilot users from several teams. Collect a pre-launch survey and deploy the browser extension. Run a kickoff session with office hours afterward. One support engineer recommends testing adoption across several groups during the trial before buying for everyone. Vendr reports that Glean minimums often start around 100 to 250 users, so agree the pilot size before the contract fixes it.
Content: authoritative answers seeded
Will the first searches return official content or casual chat?
Look forPublish ten or more Answers for repeated questions before launch. Add Go Links and Announcements, plus verified documents and pinned results. An engineer reported that Glean, connected to Slack, told a colleague a real fire alarm was a scheduled test.
Review practice: measure monthly use by team
Who is using Glean each month, for what, and who stopped?
Look forCompare monthly active use by department with the pilot baseline. A Pure Storage reviewer believes no one else on the team uses it regularly. Another company gives gift cards to its heaviest users.
Cost control: limits before company-wide seats
What happens to the bill when agents and Premium models spread?
Look forSet a company-wide monthly usage limit. Where needed, add tighter ones for departments and for single users or agents. Configure alerts and disable Premium models when Standard models suffice.
Questions to ask vendors
- Which of our sources have native connectors, and which rely on MCP tools or the Indexing API?
- What credit allowance or Model Hub commit does our contract include, and what does an extra FlexCredit pack cost?
- Which deployment model, Glean Hosted or Customer Hosted, and which region will our tenant use?
- What adoption data can we export by department during the pilot?
Red flags
- Connecting every source on day one without reviewing what each one overshares.
- Launching to the whole company before Answers, Go Links, and verified documents exist.
- Measuring the rollout by logins or seats assigned and never by monthly active use by team.
- No usage limit in place when agents start running on schedules.
