Ask a question about a step and keep the decision

Ask a named person about a step, answer with words or a link, and accept the answer as a decision kept beside the step and in Notes.

In short

Questions keep the "who decided this, and why?" with the design. Ask a person about a step or the whole design; they answer with words, a message of the discussion or a note. An editor then accepts the answer as a decision: it is shown beside the step, in each card's brief, and in the design's decision note.

Before you start

Who: asking a question needs View only. Answering needs the person asked to be able to open the design. Accepting a decision is for an editor (Edit).
Plan: Designer is part of every plan, Free included. The Free plan limits how many designs a workspace keeps; Plan & usage shows the limit and what you hold. Decisions are added to Notes, which is part of every plan.
First: nothing. Pick the person who knows; they must be able to open the design.

Steps

Open the design, choose "Review" and then "Questions and decisions" - or select a step and press "Ask about this step".
Press "Ask a question", choose what it is "About", write "Your question" and choose "Who you ask".
Press "Ask". They are told in their inbox.

Open the question and press "Answer".
Write the answer, or choose "Where it was answered": a message of the discussion or a note about this design.
Press "Send the answer".

On an answered question, press "Accept as decision" and adjust the words.
Choose the "Notebook of the decision note", or "Keep it on the question only".
Press "Accept as decision".

Result: "Decision accepted and added to the decision note", with "Open the decision note".

Good to know

The person you ask must be able to open the design.
On the canvas, a step or part with decisions wears a green chip with how many. Point at it to read the newest decision.
The notebook is chosen the first time; later decisions join the same note.
Removing a question takes it off the design and offers Undo. A decision already added to Notes stays there.
To talk about what the drawing shows, pin a comment to it instead. See /help/designer/design-comments.

If something goes wrong

"Decision accepted. It was not added to Notes: ..." - the decision is kept on the question; the reason says why Notes refused it.
"It points at something you cannot open." - the answer links a message or note you do not have access to.
