Lab and exercises
Lab
MID-065-LAB1 · Owner's pack
Outcomes: 1–4 · Time: ~2 h
- Choose one Shop service and create its ownership page: purpose, owners, SLOs, dashboards, runbooks, dependencies, known risks.
- List the top three technical debts with evidence, cost, effort, and a decision.
- Run the production readiness checklist and record evidence.
- Write a short health and trade-off note for product.
Acceptance: passes the readiness checklist.
Exercises (assessment: readiness review; five exercises)
| ID | Outcome | Task |
|---|---|---|
| MID-065-EX01 | 1 | List ten items an ownership page for inventory must contain and say why each matters. |
| MID-065-EX02 | 2 | Given a spent error budget, a feature request, and three debt items, make a prioritization with evidence. |
| MID-065-EX03 | 1 | Review a noisy alert list (twelve alerts) and decide which should page, which should ticket, and which should be deleted. |
| MID-065-EX04 | 3 | Run the readiness checklist for one service and list failed items with risk. |
| MID-065-EX05 | 4 | Write a one-paragraph note to product explaining a reliability-first quarter and its trade-offs. |
Show solutions
- EX01 Purpose, owners and contacts, SLOs, dashboards, alerts, runbooks, dependencies, data stores, cost, known risks and debt: each lets another person operate or change the service.
- EX02 Reliability first while the budget is spent; show evidence (incidents, lost hours); schedule the debt item with the highest cost per effort; give product a date for resuming features.
- EX03 Page only on user-visible symptoms or SLO burn with a runbook; ticket for slow-burn issues; delete alerts nobody acts on.
- EX04 Evidence per item (link or test result); failed items ranked by impact and likelihood, with owners and dates.
- EX05 Start with the decision; state SLO performance, the cost of staying the course, what is delayed, and the date to review.

Practical part
Five exercises MID-065-EX01 to EX05 plus the lab. Pass: at least four exercises correct and an owner's pack that passes the readiness checklist.
Common mistakes
Ownership as "I wrote it"; debt listed but never prioritized.
Assessment
Readiness review.
