Sanlam improves user experience and productivity by empowering engineers with GitHub Copilot

“I feel five times more productive!” or “The quality of my work has improved even further”—these are all things that engineers at Sanlam have said about GitHub Copilot. Now, Sanlam’s engineers have a helpful virtual colleague in Copilot, which offers suggestions, code optimization, refactoring into modern languages and generation of unit test data sets on the go. Engineers have saved up to 30% of their time while also improving code quality.

Why it matters

Coding agents are moving from autocomplete to doing whole tasks: reading a codebase, making a plan and changing many files. This case is a concrete example of where that works in practice. It is one of 221 sightings filed under Software Development on Agent Sightings (number 61 by interest), and one of 47 involving GitHub Copilot.

How you could try it

Here is a reusable prompt, written by us in our own words, that captures the task. Paste it into GitHub Copilot or any similar agent and adjust the details to your situation.

I want a coding agent to plan first, work on a branch, and show me the diff before anything is merged. The tool in the source case was GitHub Copilot.

Saved

Tip: Work on a fresh branch, ask for a plan before edits, and review the diff and test results before merging.
