One delivery email, practice three rounds of revisions

Use the same fictional task to practice adding facts, clarifying questions, and condensing text, and compare the effects of each round of revisions.

Classes and Methods

Supplement the facts first, then adjust the expression

The prompt word lessons practice discovering problems, modifying conditions, and checking again. Putting the results before and after the modification together, you can see which instruction played a role.

versionTasks given to AIWhat to check
first timeWrite a delivery follow-up email to the supplier.Did you write out the order number or arrival date out of thin air?
second timePlease write an email to the supplier according to the record: Order A, the supplier has not yet responded with a delivery time. Ask about the estimated delivery date and possible influencing factors in a calm tone and do not promise the arrival date.Keep unknowns? Is it easy for the other party to respond to the questions item by item?
third timeKeep the above facts and write them into three questions. The text should not exceed 150 words.Did you lose a key condition when shortening the text?

The above are fictitious classroom tasks and do not represent real orders.

Output comparison

With each revision, what specifically changed?

The following are output examples written for explanation and are not actual measurement records of a certain model. Check whether the newly added information is based on the previous instructions.

Round 1 · Lack of materials

It looks complete, but it adds up to the facts

Hello, Order A has been confirmed to be shipped this Friday. Please ensure it arrives next Monday and provide the logistics tracking number.

Check:The original instruction does not have an order number, shipping date and arrival date, and these contents cannot be used directly.

Round 2 · Adding known facts

Leave unknown information as questions

Hello, I would like to follow up on the shipping arrangements for order A. We have not yet received a delivery date. Please inform us of the estimated delivery date and factors that may affect the arrangement to facilitate our subsequent coordination. Thanks.

Check:Order A is from supplementary materials; shipping time is still to be confirmed, no delivery date has been promised for the supplier.

The third round·Let the other party reply item by item

Shorten text and keep key conditions

Hello, the delivery time of order A has yet to be confirmed, please help reply:
1. When is the product expected to be shipped?
2. What factors may affect the arrangement?
3. If it is not yet certain, when will the progress be updated?
Thank you.

Check:The three questions are easy to respond to, the text is less than 150 words, and the unknown date is still not written as a fact.

Classes and Methods

Keep a checklist for the next task

Reproducible mission statement

Task: What do I need to accomplish? Background: To whom, what is the current situation? Materials: What confirmed information will be used only? Boundaries: What facts cannot be filled in, and how to mark missing items? Output: What are the length, language and format requirements? Review: What numbers, sources and commitments must I check?
Do you need to memorize fixed formulas?

Memorization is not required. The key is to see what is missing in the results and then add the corresponding materials, restrictions or inspection requirements.

What is the difference from the basic course?

The basic course starts with first use and fact review; this course is suitable for people who have already used AI, but the output is unstable, and focuses on multiple rounds of modifications and comparisons.
