All engineering teams run into trouble from time to time. Alert fatigue, caused by technical debt or a failure to plan for growth, can quickly burn out SREs, overloading both development and operations with reactive work. Layer in the potential for communication problems between teams, and we can find ourselves in a place so troublesome we cannot easily see a path out. At times like this, our natural instinct as reliability engineers is to double down and fight through the issues. Often, however, we need to step back, assess the situation, and ask for help to put the team back on the road to success. We will look at the process for Code Yellow, the term we use for this process of “righting the ship”, and discuss how to identify teams that are struggling. Through a look at three separate experiences, we will examine some of the root causes, what steps were taken, and how the engineering organization as a whole supports the process.

- 12. Problem Statement Technical Debt • Written documentation needed improvement • Deployment infrastructure needed investment • Alert Fatigue Traffic-SRE
- 13. Problem Statement Resource Allocations • Backlog of work for clients • Staff shortage
- 16. Problem Statement Capacity Planning • Multi-tenant Infrastructure • No resource controls • Unclear resource ownership • Ad-hoc capacity planning • Sudden 100% increase in traffic
- 17. Problem Statement Alert Fatigue • Multiple applications overutilized • No time for proactive work • Most alerts non-actionable

- 20. Building a formula for success Define the areas that need attacking Problem Statement Communicate expectations with clients & partners Communication & Partnerships Define success criteria Exit Criteria Get the help that you require Resource Acquisition Plan for short-term & long-term Planning
- 21. Define the areas that need attacking Problem Statement • Admit there is a problem • Measure the problem • Understand the problem • Determines underlying causes that need to be fixed Building a formula for success
- 22. Define success criteria Exit Criteria • Define concrete goals • Define concrete success criteria • Measure via an operational metric • Measure via a project being completed • Define timelines for completion Building a formula for success
- 23. Get the help you require Resource Acquisition • Ask other teams for help • Get dedicated engineers/ project managers/ other roles as required • Set exit-date for resources Building a formula for success
- 24. Plan for the short-term & long-term Planning • Plan out short-term work • Plan out longer-term projects • Do they need to be rescheduled? • Prioritize work that will reduce toil & burnout (Automation + Measurement) Building a formula for success
- 25. Communicate expectations with clients & partners Communicatio n & Partnerships • Communicate problem statement & exit criteria • Send regular progress updates • Ensure that stakeholders understand delays & expected outcomes Building a formula for success
