Identify how failures are impacting stable branches and deployment pipelines

Problem Statement

So far in the Pipeline Stability track and in the MR Cycle Time project, we focused on most merge request pipelines and some of the default branch pipelines.

Optimizing for most of the merge requests pipelines might leave some engineers with unacceptably slow merge request pipelines. This seems to be the case for stable branch pipelines, sometimes taking around 3 hours to complete.

Having an overview of the post-merge deployment pipelines would also help us understand whether the work we are focusing on would improve those pipelines as well, or whether we would need a different approach for them.

Goal

Have a discussion with the groupdelivery-release group to understand their pain points when it comes to pipeline stability for stable branch pipelines and for deployment, post-merge pipelines.
