Put your review packet to the test

Close the worked answers and examine what you produced. A useful review lets another engineer follow your decision, challenge an assumption and test the proposed control. Use the prompts below to find the part that still needs work.

Check the artifacts

  1. Decision and fixture contract

    Have you named the required event, authorized scope and actual observation point? Does the fixture retain the permission check and state needed to test that event?

  2. Observer and reference audit

    Can you distinguish a target failure from a collection or scoring mistake? Are unresolved effects and reference disagreements still visible?

  3. Estimate and comparison record

    Have you retained selection weights, case-level pairs, useful-work outcomes and the assumptions behind any zero-event bound?

  4. Assessment and correction note

    Can you trace each recommendation to its evidence, revise an affected claim without erasing history, and name the owner and verification needed next?

For each prompt, point to a decision in your own work. If you can only repeat the lesson's wording, revisit its exercise and explain what would change your answer.

TRY A CHANGED REQUIREMENT

Can the reasoning travel?

A fictional team adds a new language and a delayed publication worker to an evaluated assistant. Identify which case selection, observation and comparison assumptions change. Write a revised study plan and state which earlier evidence remains useful before recommending the next assessment step.

Write the revision before checking the course examples. Name the changed boundary, a justified decision, a remaining uncertainty and a test that could disprove your conclusion. Use fictional data or work you are authorized to review.

Choose your next step

If the decision still feels uncertain, return to the project and compare your revised memo with its worked feedback. Check your reasoning about scope, metrics, evidence, release decisions and incident uncertainty.
