I did some investigation on Jira board. There was a story in Oct to design solution for a problem and a senior engineer has commented saying it was done.

The same story opened again in December and another senior engineer has commented saying "canonical and solution is designed"

But FUCKING IDIOTS didn't do anything! Last sprint I got the development story for same and I have been fucking waiting for them to give me solution. But idiots are way too lazy to do any work!
