"Is this good?" gives a reader little guidance about the feedback you need. A more useful request is, "Could you read the opening paragraph and tell me what you think the main claim is?" The answer will show whether the intended message is visible.
Name the stage of the work: "This is an early outline, so I am checking the order of ideas rather than individual spelling mistakes." This helps the reviewer spend effort where you can use it.
Choose an observable question
For instructions, ask, "Which step would you do after opening the form?" For a story, ask, "Was it clear why the character left?" These questions invite evidence about understanding instead of a general polite judgment.
If you need the response by a certain time, ask whether that is possible: "Would you have time to comment before Thursday?" Include only the necessary material and make access easy through the appropriate channel.
Practice receiving an answer without immediately defending your wording. You can ask, "Which sentence gave you that impression?" before deciding how to revise. Thank the reviewer and make your own final decision about the text. Focused feedback does not require accepting every suggestion; it gives you better information about the reader's experience so you can improve a specific part of the message.
