Investigate plausible root causes of an observed anomaly

A metric moved outside its usual range and the merchant needs to know which recent change explains it. In this case, the immediate task is to investigate plausible root causes of an observed anomaly. The workflow should produce the most plausible cause with the evidence used and the next check that would confirm it.

ai-prompt.txt
Act as a Shopify operations specialist.
Help me investigate plausible root causes of an observed anomaly.
My store context is [describe the business, products and target audience].

My scope is [specify the affected products, pages, customers or reporting period]. Use these inputs: [the affected metric, its first observed timestamp in the merchant's reporting timezone, the expected range, the segments affected, and the change log covering campaigns, catalogue edits, pricing updates, theme or app changes and deployments in the preceding window]. Test each candidate cause against the timing, direction and segment shape of the movement, keeping only those the evidence supports and discarding any whose earliest possible effect postdates the start or that cannot explain why unaffected segments stayed flat.
Return the most plausible cause with the evidence used and the next check that would confirm it for the specified task.
Show the relevant evidence or before-and-after examples and explain how I can verify the result.
If essential data is missing, ask for it and mark unsupported conclusions as unknown.
Do not invent metrics, product claims or customer facts.
For any publication, message, account or store change, use only connected tools within my explicitly authorized scope and report success only after verification; otherwise provide the draft or proposed steps.

How to solve

A recommended resolution workflow

Split the work into input, judgment, and deliverable phases. Verify each step's output before moving to the next.

01

Step 1

Pin down the anomaly by naming the affected metric, the first timestamp at which it appears in the merchant's reporting timezone, its expected range and the segments affected, then pull the change log for campaigns, catalogue edits, pricing updates, theme or app changes and integration deployments covering the window before that first timestamp.

02

Step 2

Test each candidate cause against the timing, direction and segment shape of the movement, keeping only those the evidence supports and discarding any whose earliest possible effect postdates the start or that cannot explain why unaffected segments stayed flat.

03

Step 3

Deliver the most plausible cause with the evidence it rests on, the alternatives ruled out and the reason each failed, and one decisive follow-up check naming the record to inspect and the pattern that would confirm the cause.

FAQ

Common questions when running this scenario

Cover decision rules, frequent misunderstandings, and required inputs so the team aligns on prerequisites before execution.

Why fix the first observed timestamp before hypothesising?

The start moment narrows candidates to changes landing just before it, while anything shipped after the movement began cannot have caused it, which eliminates a large share of superficially plausible explanations before any testing.

Is the first explanation usually the right one?

Seldom. Candidates are listed from the change log and eliminated one by one against timing, direction and segment shape, so what remains is the only cause the supplied records cannot contradict.

When does a root cause count as confirmed?

When the alternatives are ruled out on the record and a follow-up check reproduces the same pattern, ideally by reverting the suspected change inside a controlled window and watching the metric return to its expected range.
