Phase 5: Audit and Explain — Prove Your Ledger Is Reliable

Technical Check + Explain Which Control Matters Most

Demonstrate your understanding of self-auditing formulas and explain why they matter for Sarah's investor presentation.

Technical Check: Self-Auditing Formula Mastery
Answer all questions to show you understand how Sarah's ledger catches errors automatically.

1. What does the formula =SUMIF(LedgerTable[Account], "Cash", Ledger LedgerTable[Debit]) calculate?

2. Sarah adds a new transaction to her ledger. What happens if she used structured references in her formulas?

3. A trial balance that shows 'Balanced' proves what about Sarah's ledger?

4. Why is conditional formatting that highlights 'Out of Balance' important for Sarah?

5. Which audit check would matter most to an investor reviewing Sarah's ledger?

Brief Artifact Task: Which Check Matters Most?

Task: Write a 2-3 sentence explanation for an investor audience. Answer this question:

"Which self-audit control in Sarah's ledger matters most for proving reliability to investors, and why?"

Example Answer Structure:

"The trial balance verification matters most because it proves that Sarah's ledger follows double-entry bookkeeping rules—total debits always equal total credits. This mathematical proof gives investors confidence that the financial data is accurate before they make investment decisions."

Key Point: Focus on reliability and investor trust. Explain how the control catches errors—don't just describe the formula syntax. Investors care about risk reduction, not Excel mechanics.
