Use when Phase 1 context and handoff exist, and business questions are vague, duplicated, unprioritized, unmapped to consumers, or needed before KPI and data product design.
des-business-questions
Purpose
Use this skill to create and validate the Business Question Catalog for any data engineering project.
This skill helps the agent understand the business problem, target consumers, downstream use cases, decision context, maturity level, constraints, risks, and initial success criteria before technical design or implementation begins.
In the Phase-Orchestrated Support Model, this phase is not Done when the Business Question Catalog is first written.
Phase 02 is Done only when:
Business Question Catalog exists
+ Phase 01 artifact and handoff are reviewed
+ required question validation work is identified
+ question evidence is collected or waived with reason
+ artifact is revised from evidence
+ Phase 02 Done Gate passes
+ Phase 02 to Phase 03 handoff exists
When To Use
Use this skill when:
Phase 01 Business Discovery is complete or available as a draft with accepted risk;
Phase 01 handoff exists or the user explicitly accepts the risk of continuing without it;
stakeholders, consumers, target decisions, or expected value are known enough to derive questions;
the user wants dashboards, reports, APIs, ML datasets, data products, or analytics but the exact questions are unclear;
existing questions are vague, duplicated, unprioritized, or not mapped to consumers;
the workflow router selects Phase 02.
Do not use this skill to define final KPI formulas, design tables, choose data sources, write SQL, design dashboards, create data contracts, or implement pipelines.
Identify output_file, template_file, checklist_file, status_file, and required upstream artifacts.
Identify Phase-Orchestrated Support files:
phase_support_plan_file;
phase_evidence_pack_file;
phase_artifact_revision_file;
phase_done_gate_file;
phase_handoff_file.
Load only steps/step-01-context-and-readiness.md.
Do not load step-02 or step-03 until the current step explicitly instructs you to continue.
Stop at every HALT point and wait for user input.
Do not invent stakeholder priorities, consumer needs, target decisions, or business questions without evidence.
Do not define final KPI formulas in this phase.
Do not design tables, pipelines, contracts, dashboards, semantic models, APIs, ML models, or code.
Before marking Phase 02 as Done, create or update the support plan, evidence pack, artifact revision notes, Done Gate, handoff, and workflow status.
Process Overview
The detailed execution procedure lives in steps/.
At a high level, this skill will:
Confirm Phase 01 context and handoff are available.
Extract consumers, target decisions, expected value, scope, and constraints.
Generate candidate business questions.
Rewrite vague asks into answerable questions.
Classify and prioritize questions.
Map questions to consumers and decisions.
Identify dependencies, freshness expectations, grain hints, and candidate answer formats.
Mark candidate metrics as candidates only.
Ask HALT questions for priority, ambiguity, unsupported questions, and scope conflicts.
Draft the Business Question Catalog.
Create the Phase 02 Support Plan.
Collect or reference Phase 02 evidence.
Revise the Business Question Catalog using evidence.
Run the Phase 02 Done Gate.
Create the Phase 02 to Phase 03 Handoff.
Update workflow status.
Recommend the next skill.
Do not execute this overview directly. Follow the step files.
Phase-Orchestrated Support Model
Phase 02 uses business-question validation support work.
The purpose is not technical implementation. The purpose is to prevent downstream phases from designing KPIs, sources, marts, and contracts from vague or unprioritized questions.
Required Support Work
Support Work
Purpose
Output
Phase 01 Handoff Review
Check that questions are derived from validated Phase 01 context.
Evidence pack section
Question Quality Review
Ensure questions are answerable, useful, scoped, and business-readable.
Evidence pack section
Consumer Mapping Check
Ensure each P1 question maps to a consumer.
Evidence pack section
Decision Mapping Check
Ensure each P1 question maps to a decision or use case.
Evidence pack section
Scope Alignment Check
Ensure questions fit Phase 01 MVP scope or are marked future/out-of-scope.
Evidence pack section
Priority Validation
Ensure top questions are prioritized or marked Draft.
Evidence pack section
Answerability Risk Check
Flag questions that may not be answerable with plausible data.
Evidence pack section
Phase 02 Done Gate
Decide whether Phase 02 is Done, Done with risks, or Blocked.
phase-02-done-gate.md
Phase 02 Handoff
Tell Phase 03 what can safely be used.
phase-02-to-03-handoff.md
Optional Support Skills
Existing support or learning skills may be used when helpful:
Phase 05 source assessment needs to know which questions may be hard to answer
Handoff To The Next Skill
Recommend des-requirements-and-kpis only after:
Business Question Catalog exists
+ Phase 02 support plan exists or is waived with reason
+ Phase 02 evidence pack exists or evidence is waived with reason
+ Phase 02 Done Gate is Pass or Pass with risks
+ Phase 02 to Phase 03 handoff is Ready or Ready with Risks
If the phase is Draft or Blocked, recommend one of:
continue des-business-questions
return to Step 02 prioritization
resolve HALT question
route back to des-business-discovery
des-wise
des-correct-course
