- Record only what the transcript shows was agreed as a decision.
- If people disagree and nobody settles it, put it under Open questions with each position and who holds it.
- Every action item needs an owner and a due date as stated; if none was stated, write "owner not assigned" or "no date set".
- Maximum 250 words. Do not add dates, amounts, names or commitments that are not in the transcript.

Teams meeting "New booking system — weekly check-in", 2026-10-21, fictional company Example Clinics Group. Priya (Project lead): Vendor says the build is on track. I'd like go-live on Monday November 16. Marco (Operations): November 16 is too tight for front-desk training. I want November 23. Priya: Let's not fix it today — I'll ask the vendor about a training sandbox first. Marco: Fine. Either way I'll book the large training room for front-desk staff. Priya: Good. I'll send the signed vendor contract to finance by October 28. Sam (Finance): And the extra licence budget — let's park that until finance replies on Friday. Marco: Someone also needs to update the patient FAQ page before go-live. Priya: Agreed, we need that. Let's figure out who next week. Sam: One more thing — we agreed to keep the old system read-only for 90 days after go-live, right? Priya: Yes, confirmed, 90 days read-only.

Explain a PivotTable to your manager in 150 words, with exact numbers

Turn a pasted PivotTable (region by quarter) into a short, accurate summary for a manager, flagging the (blank) row instead of hiding it.

ClaudeTested with claude-sonnet-5 · 5 of 5 criteria on average · 3 runs graded
You are helping an analyst explain an Excel PivotTable to a manager who will not open the file.

Write a summary of at most 150 words based ONLY on the PivotTable output below:
- Give the grand total and each region's full-year total exactly as shown.
- Say which quarter had the highest and which the lowest total.
- If something in the table looks like a data problem, say what it is and what to check.
- Do not calculate percentages or growth rates, and do not guess reasons (seasonality, campaigns, staffing…) for any number.

[Paste the PivotTable output as text: row labels, column labels, values and the Grand Total. Remove client names.]

XLOOKUP client names into an invoice list, with a clean "Not found"

Pull client names from a second sheet into your invoice list, show a readable message instead of #N/A, and total one client's invoices.

ClaudeTested with claude-sonnet-5 · 5 of 5 criteria on average · 3 runs graded
You are an Excel helper for a small-business bookkeeper. Work ONLY from the two tables below.

1. Write ONE formula for cell D2 of the Invoices sheet that returns the client name for the client ID in B2 and can be filled down to D13. When the client ID is not in the Clients sheet, the cell must show the text "Not found" instead of an error.
2. List every invoice row (row number and invoice number) that will show "Not found".
3. Write a formula that returns the total amount of all invoices for client ID C-104, and state the result it returns on this data.
4. Explain in plain English, in at most 120 words, how the lookup formula works.
5. End with a short "Check before using" note for anything in the data a person should verify.

Do not invent client names, IDs or amounts that are not in the tables.
