Practise vocabulary for postmortem action items: corrective actions, preventive actions, owners, due dates, and follow-up tracking.

A ___ action addresses the immediate cause of an incident — for example, patching the vulnerability that was exploited.
Corrective actions fix the immediate, specific failure — patching, reverting a config, adding a missing validation. They address 'this specific incident' rather than 'the class of incidents this represents'.
2 / 10
A ___ action addresses the underlying systemic condition — for example, adding automated config validation to prevent the class of errors.
Preventive actions target root causes to prevent recurrence of similar incidents. 'Add automated config validation to all deployment pipelines' prevents the class of 'config error deployed' incidents, not just this one.
3 / 10
Good action items in a postmortem should be ___ — specific, measurable, and assigned to a named owner with a due date.
Actionable items are specific ('Add a circuit breaker to the payment service API client'), measurable (testable completion), and assigned with a due date. Vague items like 'improve monitoring' never get done.
4 / 10
The postmortem facilitator should track action items for ___, following up in the next retrospective or incident review cycle.
Action items without follow-up rarely get completed. The facilitator (or their manager) should track progress in the next sprint review, incident review meeting, or via a dedicated incident tracking board to ensure items close.
5 / 10
When an action item from a previous postmortem was not completed, the appropriate response is to ___.
Incomplete action items should be re-evaluated: was it the right action? Does it still apply? If yes, re-assign with a new due date and potentially a different owner or more resources. Closing without completion signals the actions aren't valued.

Code Review Comment: 'This function doesn't handle the edge case where the input string is empty. It should return an error or a default value.' Which of the following best describes the action item derived from this comment?
// TODO: Handle empty string input
This comment highlights a specific defect – the lack of handling for empty strings. The correct action item is to implement error handling to address this edge case. Ignoring the comment or refactoring the entire codebase are unnecessary and distract from the immediate problem. A unit test is useful but doesn't solve the underlying issue.

Slack Message: '@john.doe – Can you please investigate why the API endpoint /users is intermittently returning a 502 Bad Gateway error? We've seen it spike over 10% in the last hour.' Which action item should John immediately focus on?
// Investigate API Endpoint Errors
The Slack message clearly indicates an ongoing issue with a specific API endpoint. John needs to investigate the root cause of the error, which involves examining server logs for relevant information. Deploying a new version or contacting DevOps without understanding the problem is premature and inefficient. Ignoring the message delays crucial troubleshooting.

PR Description: 'This PR adds support for OAuth 2.0 authentication to our mobile app. It includes the necessary API calls and UI components.' The following action item is most relevant based on this description?
// Implement OAuth 2.0 Integration
While encryption, rate limiting, and dependency management are important, the primary action item based on adding OAuth 2.0 is to perform comprehensive security testing. This includes verifying the flow's integrity and identifying potential vulnerabilities like authorization bypass or session hijacking. The other options represent good practices but aren't directly tied to the core change.
9 / 10
Standup Update: 'I spent yesterday investigating the slow database queries. I identified a missing index on the users table, which is causing performance degradation.' Which of the following represents a suitable action item derived from this update?
// Add Index to Users Table
The core action item is to implement the solution – adding the index. Monitoring the query performance after implementation is crucial to verify that the change has indeed resolved the slow queries and doesn't introduce any new issues. While documentation and migration are important steps, they follow from successful implementation.

Postmortem Discussion: 'The team discussed the recent outage caused by a misconfigured load balancer. The action item to prevent recurrence was assigned to Sarah.' How should the facilitator track this action item?
// Track Action Item - Sarah
Tracking action items requires proactive monitoring and accountability. Scheduling regular check-ins ensures that Sarah remains on track and that any roadblocks are identified and addressed promptly. Simply assigning responsibility without follow-up risks the action item falling through the cracks. High priority is appropriate to ensure timely resolution.
What will I practice in "Action Items Tracking Language"?
This is a Post Incident Facilitation exercise set. It walks through 10 scenario-based multiple-choice questions built around real usage of post incident facilitation terminology that IT professionals encounter on the job.
Is this exercise free to use?
Yes. Every exercise on CoderSlingo, including this one, is free to complete with no account, sign-up, or paywall.
How many questions are in this exercise?
This set contains 10 questions. Each one shows immediate feedback and a detailed explanation after you answer, so you learn the correct usage right away rather than waiting for a final score.
Do I need prior experience to complete this exercise?
No prior experience is required. Each question includes a full explanation covering the reasoning behind the correct answer, so the exercise itself teaches the post incident facilitation vocabulary as you go.
Can I retry the exercise if I get questions wrong?
Yes — use the "Try again" button on the results screen to reset your answers and go through all the questions again. There is no limit on attempts.
Is my progress saved?
Your answers and score for the current session are tracked in the browser as you go. No account or login is needed, and there is nothing to install.
What if I don't understand a term used in a question?
Read the explanation shown after you answer each question — it breaks down the correct term in plain English with a real-world example. You can also check the site Glossary for quick definitions.
How is this different from reading a blog article on the topic?
Exercises like this one are interactive drills that test and reinforce specific vocabulary through multiple-choice questions, while blog articles explain concepts in prose. Practising here after reading builds active recall, not just passive recognition.
