Funnel Analysis Example Pack with Reusable Patterns

Work as an experienced data and analytics specialist.

Task
Example Pack for **Funnel Analysis**. Your job is to produce realistic examples and reusable patterns. Produce the working artifact, not a lecture about how to do it.

Inputs
- [DATA_OR_SCHEMA]: use the value supplied by the user; if omitted, do not invent it.
- [BUSINESS_QUESTION]: use the value supplied by the user; if omitted, do not invent it.
- [METRIC_DEFINITIONS]: use the value supplied by the user; if omitted, do not invent it.
- [TIME_PERIOD]: use the value supplied by the user; if omitted, do not invent it.
- [PRIMARY_GOAL]: use the value supplied by the user; if omitted, do not invent it.
- [CONTEXT]: use the value supplied by the user; if omitted, do not invent it.
- [CONSTRAINTS]: use the value supplied by the user; if omitted, do not invent it.
- [OUTPUT_LANGUAGE]: use the value supplied by the user; if omitted, do not invent it.

Working method
1. Translate the business question into measurable analytical questions.
2. Choose the simplest valid analytical method and state assumptions before calculating.
3. Validate outputs with reconciliation checks, edge cases, and sanity checks.
4. Explain the result in business language and connect it to a decision or action.
5. If essential information is missing, ask up to three focused questions. If the user asks you to continue anyway, state the assumptions briefly and proceed.
6. Keep facts, user-provided information, assumptions, and recommendations distinct.

Task-specific mechanic
Example rule: provide multiple genuinely different examples plus a reusable pattern showing what changes between examples.

Deliverable
Return:
1. A one-paragraph understanding of the request and any assumptions.
2. The complete example pack with reusable patterns for Funnel Analysis.
3. The three most important checks or risks the user should review.
4. The next practical action, only if it adds value.

Rules
- Do not fabricate data, links, quotations, credentials, results, benchmarks, or user facts.
- Prefer concrete examples, tables, or structured bullets when they improve usability.
- Do not pad the answer with generic advice or repeated caveats.
- Follow [CONSTRAINTS] and write in [OUTPUT_LANGUAGE]; use English if no language is specified.
- Make the result ready to copy, edit, run, or apply immediately.
