Ask HN: What tools or processes accelerate engineer onboarding?

I recall onboarding a US-based software engineer in 2018-19 was estimated at ~$80–120K (salary, lost productivity, and ramp time). A recent research publication from DX (AI-Assisted Engineering: Q4 Impact Report) [1] offers updated data that reframes how we think about onboarding.

Here are three relevant facts from the report:

1. Onboarding speed improvement:

Engineers using AI coding assistants daily reached their 10th merged pull request in about 49 days, compared to about 91 days for engineers not using new AI-powered tools.

2. Time savings per engineer:

Developers using AI tools report saving about 3.6 hours per week.

3. High adoption of AI tools

Over 90% of developers across the sample use AI tools at least monthly.

Curious how y'all feel about this info from where you're sitting.

Few immediate caveats:

- I definitely feel that DX has a biased sample because eng orgs that use them are surely forward thinking and the leadership value developer productivity. - The 10th merged PR is a DX metric, so it's possible that's not the best or there's a better metric design.

Questions for the community:

1. Call the BS, what's not true in your world?

2. What tools & processes do you swear by, what have you found that doesn't move the needle?

3. Is Onboarding even a problem to focus on and what's a definition of good enough for that process?
