Problem

Qualtrics wanted to improve developer productivity while protecting proprietary code. Writing tests and understanding existing code consumed engineering time.

Approach

Its developer-experience team evaluated AI coding assistants in summer 2023 and selected Cody. The tool worked with its self-hosted GitLab setup and offered a choice of language models. Engineers used it to explain code and generate tests.

Results

25%faster code understanding reported by engineers, per SourcegraphVendor case study[1]

roughly 10 minutesreported unit-test writing time, previously a full day, per SourcegraphVendor case study[1]

Takeaway

Compatibility with the existing code-hosting environment helped the rollout. The productivity figures came from engineer reports.
