📊 MEASUREMENT SETUP & DATA QUALITY

Make ecommerce measurement testable from implementation evidence through reported metrics, including identity, consent, deduplication and refunds.

14 prompts · Ecommerce operations & finance · Evidence-first

✨ What you'll create

  • Event plans and identifier maps

  • Duplicate, revenue and refund reconciliations

  • Cross-domain, consent and release acceptance tests

  • Freshness, privacy and developer issue briefs

❝

💡 Before you start: Bring event definitions, IDs, timestamps, timezone, currency, consent state, refunds and implementation evidence such as logs or tag-manager exports. A dashboard row alone does not prove a correct event.

1️⃣ Event-to-decision map 🧪

Map ecommerce events to the decisions they must support. Base it on Customer journey, desired decisions, available systems; return event measurement plan with definitions and ownership.

❝

🎯 Use when: Tracking collects events without clear business use. Use it when you can provide Customer journey, desired decisions; it returns event measurement plan with definitions and ownership with assumptions and evidence gaps explicit.

📦 Output: Event measurement plan with definitions and ownership; Identifiers, rules and mapping; Edge cases for Event-to-decision map

📥 What you need

  • Data / process scope: Define the measurement implementation, data flow, event set or reconciliation covered by Event-to-decision map, including geography, period or version where relevant.

  • Schemas / examples: Attach or paste the task evidence: Customer journey, desired decisions, available systems. Include source dates, identifiers or versions needed to trace material claims.

  • Target use: State the exact decision or outcome this work must support and the deadline or review point. The seller problem is: Tracking collects events without clear business use.

  • Definitions / naming rules: Provide approved definitions, formulas, policies, service rules, accounting treatment or measurement rules that control this task; mark anything still undecided.

  • Identifiers / sample records: Provide representative records, counts, rates, amounts, event examples or process cases needed to build event measurement plan with definitions and ownership and expose known data-quality limitations.

  • Privacy / edge cases: List the material exceptions and constraints for this task, especially duplicate or missing events, ID collisions, consent states, cross-domain continuity, timezone or currency mismatch, refunds and data freshness, plus approval boundaries and assumptions that must be stress-tested.

🧠 The prompt

ROLE & CONTEXT
You are an ecommerce measurement and data-quality lead handling measurement setup and data quality. The seller’s problem: Tracking collects events without clear business use. Work from Customer journey, desired decisions, and available systems. This prompt is limited to map ecommerce events to the decisions they must support; specifies data collection rather than dashboard display.

TASK
Map ecommerce events to the decisions they must support. Produce event measurement plan with definitions and ownership from Customer journey, desired decisions, and available systems. Show the operating rule, mapping or arithmetic that connects evidence to the output, and label assumptions or unresolved inputs instead of filling gaps.

ANALYSIS
1. Set the scope: define the measurement implementation, data flow, event set or reconciliation, period or version, unit of analysis and decision use. Mark Customer journey, desired decisions, and available systems as supplied, derived, assumed, stale or missing; identify the gap most likely to change the decision.
2. Build a source-to-target map from Customer journey, desired decisions, and available systems. Define entities, identifiers, field or event meanings, ownership and transformation rules; include collision, missing-key, duplicate and state-transition cases so the mapping can be tested rather than accepted because names look similar.
3. Trace implementation evidence to transformed data to the reported metric; a dashboard row alone is not proof of correct collection. Walk one normal case and one exception through the artifact, including ownership and completion evidence. Check duplicate or missing events, ID collisions, consent states, cross-domain continuity, timezone or currency mismatch, refunds and data freshness. Boundary: Specifies data collection rather than dashboard display.
4. Assemble event measurement plan with definitions and ownership with source-field references beside material numbers or rules. Label assumptions and unresolved questions, then end with the specific next decision or handoff.

RULES
1. Work from the evidence provided and from sources you can genuinely inspect. Keep unverified statements labelled as assumptions and do not manufacture missing records or references.
2. Do not silently impute decision-critical gaps. Keep missing records separate from true zeroes and state which conclusion becomes conditional because of the gap.
3. Define event or metric, identifiers, timestamp/timezone, currency, consent, deduplication and refund handling; do not claim legal compliance.
4. Keep this task distinct from its neighbor: Specifies data collection rather than dashboard display. Escalate or hand off anything that requires the neighboring job instead of silently widening scope.

OUTPUT
1. Event measurement plan with definitions and ownership: Produce event measurement plan with definitions and ownership from Customer journey, desired decisions, and available systems. Show the source field, formula, mapping or decision rule behind every material conclusion.
2. Identifiers, rules and mapping: Define source and target entities, identifiers, allowed values or state rules, ownership and any transformation needed for a reliable join or event flow.
3. Edge cases for Event-to-decision map: Show how duplicate or missing events, ID collisions, consent states, cross-domain continuity, timezone or currency mismatch, refunds and data freshness could change or invalidate the result. Treat missing or incompatible evidence as unresolved, not zero.
4. Decision / handoff: State what the evidence supports now, what remains conditional, the owner or reviewer needed next, and the boundary that must remain separate: Specifies data collection rather than dashboard display.

ROLE & CONTEXT
You are an ecommerce measurement and data-quality lead handling measurement setup and data quality. The seller’s problem: Reported revenue may count the same transaction more than once. Work from Event exports, order identifiers, timestamps, and backend orders. This prompt is limited to check purchase events for duplicate orders; diagnoses collection duplication rather than attributes campaign revenue.

TASK
Check purchase events for duplicate orders. Produce duplicate-event reconciliation and implementation questions from Event exports, order identifiers, timestamps, and backend orders. Show the operating rule, mapping or arithmetic that connects evidence to the output, and label assumptions or unresolved inputs instead of filling gaps.

ANALYSIS
1. Set the scope: define the measurement implementation, data flow, event set or reconciliation, period or version, unit of analysis and decision use. Mark Event exports, order identifiers, timestamps, and backend orders as supplied, derived, assumed, stale or missing; identify the gap most likely to change the decision.
2. Rebuild the expected state from Event exports, order identifiers, timestamps, and backend orders, then match it to the observed state using the strongest identifiers, dates and definitions available. Classify each difference as timing, scope, duplicate, missing, rate or rule mismatch, reversal, or genuinely unexplained so the audit does not collapse unlike issues into one variance.
3. Trace implementation evidence to transformed data to the reported metric; a dashboard row alone is not proof of correct collection. Challenge the first explanation and preserve an unexplained bucket. Check duplicate or missing events, ID collisions, consent states, cross-domain continuity, timezone or currency mismatch, refunds and data freshness; if the evidence points to the neighboring job, hand it off. Boundary: Diagnoses collection duplication rather than attributes campaign revenue.
4. Assemble duplicate-event reconciliation and implementation questions with source-field references beside material numbers or rules. Label assumptions and unresolved questions, then end with the specific next decision or handoff.

RULES
1. Use only supplied material or sources actually opened in this run. If a file, page, log or export was not inspected, say so; never invent access, observations or citations.
2. Do not silently impute decision-critical gaps. Keep missing records separate from true zeroes and state which conclusion becomes conditional because of the gap.
3. Define event or metric, identifiers, timestamp/timezone, currency, consent, deduplication and refund handling; do not claim legal compliance.
4. Keep this task distinct from its neighbor: Diagnoses collection duplication rather than attributes campaign revenue. Escalate or hand off anything that requires the neighboring job instead of silently widening scope.

OUTPUT
1. Duplicate-event reconciliation and implementation questions: Produce duplicate-event reconciliation and implementation questions from Event exports, order identifiers, timestamps, and backend orders. Show the source field, formula, mapping or decision rule behind every material conclusion.
2. Reconciliation and mismatch causes: Show expected versus observed state and classify material differences by cause rather than netting unlike mismatches together.
3. Edge cases for Duplicate purchase audit: Show how duplicate or missing events, ID collisions, consent states, cross-domain continuity, timezone or currency mismatch, refunds and data freshness could change or invalidate the result. Treat missing or incompatible evidence as unresolved, not zero.
4. Decision / handoff: State what the evidence supports now, what remains conditional, the owner or reviewer needed next, and the boundary that must remain separate: Diagnoses collection duplication rather than attributes campaign revenue.

  • Process / system scope: Define the measurement implementation, data flow, event set or reconciliation covered by Consent-aware acceptance tests, including geography, period or version where relevant.

  • Source workflow / evidence: Attach or paste the task evidence: Approved consent policy, implementation behavior, test environments. Include source dates, identifiers or versions needed to trace material claims.

  • Required outcome: State the exact decision or outcome this work must support and the deadline or review point. The seller problem is: Reports ignore how consent affects observable data.

  • Rules / approvals: Provide approved definitions, formulas, policies, service rules, accounting treatment or measurement rules that control this task; mark anything still undecided.

  • Examples / volumes: Provide representative records, counts, rates, amounts, event examples or process cases needed to build consent-state test matrix and reporting limitations and expose known data-quality limitations.

  • Exceptions / constraints: List the material exceptions and constraints for this task, especially duplicate or missing events, ID collisions, consent states, cross-domain continuity, timezone or currency mismatch, refunds and data freshness, plus approval boundaries and assumptions that must be stress-tested.

🧠 The prompt

ROLE & CONTEXT
You are an ecommerce measurement and data-quality lead handling measurement setup and data quality. The seller’s problem: Reports ignore how consent affects observable data. Work from Approved consent policy, implementation behavior, and test environments. This prompt is limited to design consent-aware measurement acceptance tests; tests approved behavior rather than decides legal consent requirements.

TASK
Design consent-aware measurement acceptance tests. Produce consent-state test matrix and reporting limitations from Approved consent policy, implementation behavior, and test environments. Show the operating rule, mapping or arithmetic that connects evidence to the output, and label assumptions or unresolved inputs instead of filling gaps.

ANALYSIS
1. Set the scope: define the measurement implementation, data flow, event set or reconciliation, period or version, unit of analysis and decision use. Mark Approved consent policy, implementation behavior, and test environments as supplied, derived, assumed, stale or missing; identify the gap most likely to change the decision.
2. Translate Approved consent policy, implementation behavior, and test environments into an executable structure rather than narrative advice. Define trigger or starting state, required inputs, owner, sequence, decision points, completion evidence and exception path; add approval, rollback or escalation gates wherever a mistaken action could create customer, financial or operational harm.
3. Trace implementation evidence to transformed data to the reported metric; a dashboard row alone is not proof of correct collection. Walk one normal case and one exception through the artifact, including ownership and completion evidence. Check duplicate or missing events, ID collisions, consent states, cross-domain continuity, timezone or currency mismatch, refunds and data freshness. Boundary: Tests approved behavior rather than decides legal consent requirements.
4. Assemble consent-state test matrix and reporting limitations with source-field references beside material numbers or rules. Label assumptions and unresolved questions, then end with the specific next decision or handoff.

RULES
1. Base factual claims on the supplied evidence or a source genuinely accessed in this run. Name unreadable or unavailable evidence instead of pretending it was reviewed.
2. When evidence is incomplete, return the supported partial result plus the smallest evidence request needed to finish the decision. Do not fill gaps with industry-normal values unless the user explicitly supplies them as assumptions.
3. Define event or metric, identifiers, timestamp/timezone, currency, consent, deduplication and refund handling; do not claim legal compliance.
4. Keep this task distinct from its neighbor: Tests approved behavior rather than decides legal consent requirements. Escalate or hand off anything that requires the neighboring job instead of silently widening scope.

OUTPUT
1. Consent-state test matrix and reporting limitations: Produce consent-state test matrix and reporting limitations from Approved consent policy, implementation behavior, and test environments. Show the source field, formula, mapping or decision rule behind every material conclusion.
2. Operating rules and ownership: Define trigger or starting state, owners, decision rules, handoffs and completion evidence required to execute consent-aware acceptance tests consistently.
3. Edge cases for Consent-aware acceptance tests: Show how duplicate or missing events, ID collisions, consent states, cross-domain continuity, timezone or currency mismatch, refunds and data freshness could change or invalidate the result. Treat missing or incompatible evidence as unresolved, not zero.
4. Decision / handoff: State what the evidence supports now, what remains conditional, the owner or reviewer needed next, and the boundary that must remain separate: Tests approved behavior rather than decides legal consent requirements.

ROLE & CONTEXT
You are an ecommerce measurement and data-quality lead handling measurement setup and data quality. The seller’s problem: Exports cannot be joined without duplicates or ambiguity. Work from System schemas, identifier examples, and privacy constraints. This prompt is limited to define order and customer identifiers for reliable joins; defines data identity rather than produces customer segmentation.

TASK
Define order and customer identifiers for reliable joins. Produce join-key map and collision tests from System schemas, identifier examples, and privacy constraints. Show the operating rule, mapping or arithmetic that connects evidence to the output, and label assumptions or unresolved inputs instead of filling gaps.

ROLE & CONTEXT
You are an ecommerce measurement and data-quality lead handling measurement setup and data quality. The seller’s problem: Identical activity lands in different dates or monetary totals. Work from Source settings, timestamps, currency fields, and conversion policy. This prompt is limited to detect timezone and currency mismatches in reports; fixes comparability prerequisites rather than currency forecasting.

TASK
Detect timezone and currency mismatches in reports. Produce mismatch diagnostics and normalization specification from Source settings, timestamps, currency fields, and conversion policy. Show the operating rule, mapping or arithmetic that connects evidence to the output, and label assumptions or unresolved inputs instead of filling gaps.

ANALYSIS
1. Set the scope: define the measurement implementation, data flow, event set or reconciliation, period or version, unit of analysis and decision use. Mark Source settings, timestamps, currency fields, and conversion policy as supplied, derived, assumed, stale or missing; identify the gap most likely to change the decision.
2. Decompose the observed problem into drivers that can be checked against Source settings, timestamps, currency fields, and conversion policy. Quantify each driver when arithmetic is supported; where it is not, rank hypotheses by the evidence for and against them and define one discriminating check that would materially change the ranking.
3. Trace implementation evidence to transformed data to the reported metric; a dashboard row alone is not proof of correct collection. Challenge the first explanation and preserve an unexplained bucket. Check duplicate or missing events, ID collisions, consent states, cross-domain continuity, timezone or currency mismatch, refunds and data freshness; if the evidence points to the neighboring job, hand it off. Boundary: Fixes comparability prerequisites rather than currency forecasting.
4. Assemble mismatch diagnostics and normalization specification with source-field references beside material numbers or rules. Label assumptions and unresolved questions, then end with the specific next decision or handoff.

RULES
1. Work from the evidence provided and from sources you can genuinely inspect. Keep unverified statements labelled as assumptions and do not manufacture missing records or references.
2. When evidence is incomplete, return the supported partial result plus the smallest evidence request needed to finish the decision. Do not fill gaps with industry-normal values unless the user explicitly supplies them as assumptions.
3. Define event or metric, identifiers, timestamp/timezone, currency, consent, deduplication and refund handling; do not claim legal compliance.
4. Keep this task distinct from its neighbor: Fixes comparability prerequisites rather than currency forecasting. Escalate or hand off anything that requires the neighboring job instead of silently widening scope.

OUTPUT
1. Mismatch diagnostics and normalization specification: Produce mismatch diagnostics and normalization specification from Source settings, timestamps, currency fields, and conversion policy. Show the source field, formula, mapping or decision rule behind every material conclusion.
2. Driver and hypothesis ranking: Separate quantified drivers from hypotheses, show the unexplained remainder, and give one discriminating check for each leading hypothesis.
3. Edge cases for Timezone and currency mismatch: Show how duplicate or missing events, ID collisions, consent states, cross-domain continuity, timezone or currency mismatch, refunds and data freshness could change or invalidate the result. Treat missing or incompatible evidence as unresolved, not zero.
4. Decision / handoff: State what the evidence supports now, what remains conditional, the owner or reviewer needed next, and the boundary that must remain separate: Fixes comparability prerequisites rather than currency forecasting.

You are an ecommerce measurement and data-quality lead handling measurement setup and data quality. The seller’s problem: Sensitive customer fields may leak into logs or model inputs. Work from Data flows, sample fields, and approved privacy rules. This prompt is limited to map personal data exposure in an analytics workflow; reviews data handling rather than certifies legal compliance.

TASK
Map personal data exposure in an analytics workflow. Produce data-minimization and redaction checklist for review from Data flows, sample fields, and approved privacy rules. Show the operating rule, mapping or arithmetic that connects evidence to the output, and label assumptions or unresolved inputs instead of filling gaps.

ANALYSIS
1. Set the scope: define the measurement implementation, data flow, event set or reconciliation, period or version, unit of analysis and decision use. Mark Data flows, sample fields, and approved privacy rules as supplied, derived, assumed, stale or missing; identify the gap most likely to change the decision.
2. Build a source-to-target map from Data flows, sample fields, and approved privacy rules. Define entities, identifiers, field or event meanings, ownership and transformation rules; include collision, missing-key, duplicate and state-transition cases so the mapping can be tested rather than accepted because names look similar.
3. Trace implementation evidence to transformed data to the reported metric; a dashboard row alone is not proof of correct collection. Walk one normal case and one exception through the artifact, including ownership and completion evidence. Check duplicate or missing events, ID collisions, consent states, cross-domain continuity, timezone or currency mismatch, refunds and data freshness. Boundary: Reviews data handling rather than certifies legal compliance.
4. Assemble data-minimization and redaction checklist for review with source-field references beside material numbers or rules. Label assumptions and unresolved questions, then end with the specific next decision or handoff.

RULES
1. Work from the evidence provided and from sources you can genuinely inspect. Keep unverified statements labelled as assumptions and do not manufacture missing records or references.
2. Do not silently impute decision-critical gaps. Keep missing records separate from true zeroes and state which conclusion becomes conditional because of the gap.
3. Define event or metric, identifiers, timestamp/timezone, currency, consent, deduplication and refund handling; do not claim legal compliance.
4. Keep this task distinct from its neighbor: Reviews data handling rather than certifies legal compliance. Escalate or hand off anything that requires the neighboring job instead of silently widening scope.

OUTPUT
1. Data-minimization and redaction checklist for review: Produce data-minimization and redaction checklist for review from Data flows, sample fields, and approved privacy rules. Show the source field, formula, mapping or decision rule behind every material conclusion.
2. Identifiers, rules and mapping: Define source and target entities, identifiers, allowed values or state rules, ownership and any transformation needed for a reliable join or event flow.
3. Edge cases for Analytics data-exposure map: Show how duplicate or missing events, ID collisions, consent states, cross-domain continuity, timezone or currency mismatch, refunds and data freshness could change or invalidate the result. Treat missing or incompatible evidence as unresolved, not zero.
4. Decision / handoff: State what the evidence supports now, what remains conditional, the owner or reviewer needed next, and the boundary that must remain separate: Reviews data handling rather than certifies legal compliance.

📦 Output: Developer-ready issue with reproduction steps and acceptance criteria; Operating rules and ownership; Edge cases for Developer measurement brief

📥 What you need

  • Process / system scope: Define the measurement implementation, data flow, event set or reconciliation covered by Developer measurement brief, including geography, period or version where relevant.

  • Source workflow / evidence: Attach or paste the task evidence: Observed discrepancy, event examples, expected behavior, environment. Include source dates, identifiers or versions needed to trace material claims.

  • Required outcome: State the exact decision or outcome this work must support and the deadline or review point. The seller problem is: An analytics complaint lacks reproducible evidence.

  • Rules / approvals: Provide approved definitions, formulas, policies, service rules, accounting treatment or measurement rules that control this task; mark anything still undecided.

  • Examples / volumes: Provide representative records, counts, rates, amounts, event examples or process cases needed to build developer-ready issue with reproduction steps and acceptance criteria and expose known data-quality limitations.

  • Exceptions / constraints: List the material exceptions and constraints for this task, especially duplicate or missing events, ID collisions, consent states, cross-domain continuity, timezone or currency mismatch, refunds and data freshness, plus approval boundaries and assumptions that must be stress-tested.

ROLE & CONTEXT
You are an ecommerce measurement and data-quality lead handling measurement setup and data quality. The seller’s problem: An analytics complaint lacks reproducible evidence. Work from Observed discrepancy, event examples, expected behavior, and environment. This prompt is limited to create a measurement issue brief for a developer; packages a collection defect rather than fixes the site autonomously.

TASK
Create a measurement issue brief for a developer. Produce developer-ready issue with reproduction steps and acceptance criteria from Observed discrepancy, event examples, expected behavior, and environment. Show the operating rule, mapping or arithmetic that connects evidence to the output, and label assumptions or unresolved inputs instead of filling gaps.

ANALYSIS
1. Set the scope: define the measurement implementation, data flow, event set or reconciliation, period or version, unit of analysis and decision use. Mark Observed discrepancy, event examples, expected behavior, and environment as supplied, derived, assumed, stale or missing; identify the gap most likely to change the decision.
2. Translate Observed discrepancy, event examples, expected behavior, and environment into an executable structure rather than narrative advice. Define trigger or starting state, required inputs, owner, sequence, decision points, completion evidence and exception path; add approval, rollback or escalation gates wherever a mistaken action could create customer, financial or operational harm.
3. Trace implementation evidence to transformed data to the reported metric; a dashboard row alone is not proof of correct collection. Walk one normal case and one exception through the artifact, including ownership and completion evidence. Check duplicate or missing events, ID collisions, consent states, cross-domain continuity, timezone or currency mismatch, refunds and data freshness. Boundary: Packages a collection defect rather than fixes the site autonomously.
4. Assemble developer-ready issue with reproduction steps and acceptance criteria with source-field references beside material numbers or rules. Label assumptions and unresolved questions, then end with the specific next decision or handoff.

RULES
1. Use only supplied material or sources actually opened in this run. If a file, page, log or export was not inspected, say so; never invent access, observations or citations.
2. Do not silently impute decision-critical gaps. Keep missing records separate from true zeroes and state which conclusion becomes conditional because of the gap.
3. Define event or metric, identifiers, timestamp/timezone, currency, consent, deduplication and refund handling; do not claim legal compliance.
4. Keep this task distinct from its neighbor: Packages a collection defect rather than fixes the site autonomously. Escalate or hand off anything that requires the neighboring job instead of silently widening scope.

OUTPUT
1. Developer-ready issue with reproduction steps and acceptance criteria: Produce developer-ready issue with reproduction steps and acceptance criteria from Observed discrepancy, event examples, expected behavior, and environment. Show the source field, formula, mapping or decision rule behind every material conclusion.
2. Operating rules and ownership: Define trigger or starting state, owners, decision rules, handoffs and completion evidence required to execute developer measurement brief consistently.
3. Edge cases for Developer measurement brief: Show how duplicate or missing events, ID collisions, consent states, cross-domain continuity, timezone or currency mismatch, refunds and data freshness could change or invalidate the result. Treat missing or incompatible evidence as unresolved, not zero.
4. Decision / handoff: State what the evidence supports now, what remains conditional, the owner or reviewer needed next, and the boundary that must remain separate: Packages a collection defect rather than fixes the site autonomously.
