7.1 · Lesson 1 of 3
Diagnose Underperforming Outputs
What you need to know
Domain 7 is Troubleshooting and Optimization (10%). Lesson 7.1: before rewriting a prompt, work out what is actually wrong. Move from symptom to cause to first fix. Generic output, wrong facts, ignored instructions, and drift each point to a different cause and a different first remedy.
Symptom → cause → first fix
Generic / bland
Likely cause: Missing context, audience, or purpose
First fix: Add specifics and an example of what good looks like
Wrong facts
Likely cause: Source missing or stale
First fix: Supply or update the source and verify
Ignored instructions
Likely cause: Buried, contradictory, or too-long rules
First fix: Simplify and restate the key rule
Drift / contradiction
Likely cause: Context overload in a long chat
First fix: Summarise and restart; persist standing facts in a Project
Wrong format
Likely cause: Format never specified
First fix: State the structure explicitly; give a small example
Worked example
Four weak outputs: generic, wrong format, wrong facts, inconsistent across runs. For each, write the likely cause, check what changed (prompt, files, Project, model), apply the smallest fix that targets the cause, and rerun on the same input. Fill a table of symptom, cause, first fix, and result — that is the exam habit.
Exam traps
Rewrite the whole prompt immediately
Diagnose what changed and match the first fix to the symptom.
Use the strongest model to fix every problem
Fix the cause first — missing context, stale source, buried rule, or overload.
Treat every symptom as the same failure
Bland output, wrong facts, ignored instructions, drift, and wrong format each have different first remedies.
Skip asking what changed since the last good result
A new file, edited instruction, different model, or new input type is often the cause.
Practice scenario
A long chat that used to follow the brief now contradicts earlier decisions and forgets constraints. What is the best first fix?
