How to delegate politely & respectfully?

We currently have a problem with test flakes happening very often.

Someone is currently working on a systemic fix, but in the meantime, I've taken it upon myself to be the leader in categorizing and assigning people to take on some of the existing flakes as they happen. I am assigning based on who has the most context or who wrote the original test.

My question is: How can I assign these in a way that doesn't cause people to dislike me? I ask as someone who needs to delegate in my role but also needs to get buy-in for various initiatives so its important that people like me.

A couple of things I've tried:

• Trying to be as helpful as possible, showing that as I'm assigning these I've done a little bit of investigation myself to try to fix it (even without much context) or give any info I can gather
• Asking in a polite way (maybe)? Here's a couple examples:
  • "@person, I saw this one flake a few times and noticed you were the original author. Would you be able to take a look when you get a chance?"
  • "@person it looks like we attempted to fix this here (link to github commit) but it seems to still be flaking. If it's ok, I'm gonna assign this one to you."

Any better wording of the "ask" or advice around this situation would be appreciated!
