2
Try the "lazy prompt" first
1 minute
Type this exact prompt and see what you get:
Write an email to a vendor about an invoice.
Notice: The output is generic. The AI doesn't know who you are, who the vendor is, or what happened. This is why most people's first AI experience is underwhelming — the prompt is the problem, not the tool.
3
Try the structured prompt
2 minutes
Now paste this into the same conversation:
You are an experienced Accounts Payable Coordinator at a North Carolina community college.
Draft a professional follow-up email to a vendor who has mistakenly sent us a past-due notice.
Context:
- Vendor: Harborline Office Solutions
- Contact: Marcus Delgado, Accounts Receivable
- Invoice #HOS-4471 for $3,842.16, dated March 15, 2026
- We approved payment on March 22 and processed via ACH on April 1 (transaction #NC-882910)
- Harborline sent a second past-due notice on April 18
- We've been a customer for 7+ years with no prior billing disputes
Tone: Professional, firm but friendly. Do not admit fault. Preserve the relationship.
Constraints: Under 150 words. Request they verify their records against our ACH confirmation before escalating. Ask for written confirmation of receipt.
Sign it from: Pat Taylor, Accounts Payable Coordinator, Blueridge Coastal Community College.
Notice the difference: Same AI, completely different output. The AI didn't get smarter — the prompt got clearer.
4
Iterate — talk back to the AI
2 minutes
Revise the draft by typing this follow-up message in the same conversation:
That's good, but make it slightly warmer in the opening — we value this relationship. Also add a sentence offering to hop on a quick call if needed to resolve it.
Notice: You didn't start over. You talked back to the AI like you would to a colleague drafting on your behalf. Revisions are free.
5
Try a tone shift
2 minutes
Now try:
Now give me a firmer version — we've been patient, but we need Harborline to resolve this quickly before it affects our credit standing with them.
Notice: One prompt. Different tone. Same core facts. You now have three versions to choose from.
6
Reflect with your table
2 minutes
Discuss with your table:
Which version would you actually send?
What would you change before sending it?
What surprised you about the iteration process?
What You Just Learned
The first prompt is rarely the best one. Iteration is where quality lives.
Giving AI a role ("You are a...") changes the output completely.
Context is king. The more you tell AI about the situation, the more useful the draft.
Tone is a prompt, not a rewrite. Ask for warmer, firmer, more diplomatic — the AI adjusts.
Talk back to the AI. Don't start over. Revise like you would with a human colleague.
