How can I convince upper management not to use GitHub metrics for employee evaluations?

Help! Our higher-ups want to bring in software to monitor every GitHub action and use it for promotion and firing decisions. As someone with coding experience, I know this is a horrible way to judge engineers’ performance.

I’m looking for solid reasons to explain why this is a bad idea before it becomes our new reality. Has anyone dealt with something like this before? What arguments can I use to show leadership they’re making a big mistake?

I’d really appreciate any advice, personal stories, or facts that could help me make a strong case against this plan. I’m worried about how it might affect our team and work environment if it goes through.

// Example of why GitHub metrics are misleading
function codeQualityVsQuantity() {
  let lineCount = 1000; // Lots of code
  let bugCount = 50; // But many bugs
  
  let smallerCodeBase = 200; // Less code
  let fewerBugs = 5; // Fewer issues
  
  console.log("More code doesn't mean better code");
}

How can I get this point across to management effectively?

oof, that sounds rough. i’ve been there before. maybe try showing them some real-world examples of how github metrics can be gamed? like, ppl can just make tons of tiny commits to boost their numbers. or point out how diff coding styles affect metrics. good luck convincing the higher-ups, hope it works out!
