Responder Approval to move to CFCComments
Laura Carlson Agree
Todd Libby Agree
Sarah Horton Agree Note that resolution at the Aug 17 meeting was, RESOLUTION: Move amended Error Prevention Guideline to CFC for addition to the next update of WCAG 3.

This survey appears to be about the editorial changes we made in response to the Aug 17 survey: https://www.w3.org/2002/09/wbs/35422/wcag3-error-prevention-pre-cfc/results. You can see those edits here: https://github.com/w3c/silver/pull/548/files.

The editorial changes are not all reflected in the linked documents. Also, the text above mentions new methods, but that may be a leftover from the Aug 17 survey. There are no new methods, just a few editorial changes.
Shawn Lauriat Agree
Jake Abma Disagree for the following reason 1: ------------------

I don't think the guideline serves as a good example for preventing errors. The work done by the group has so much more information not reflected yet.

Short version: the outcome basically is a synonym for the guideline (Error prevention = Input instructions provided = Error prevention) and doesn't cover the true meaning of what the outcomes should be.

2: ------------------

There are more outcomes for intructions and the outcomes should have an AND relationship or are not applicable (N/A)

The Methods under the outcome right now do NOT have an "OR" relationship and must have one (this is what has already been discussed before).
Scoring an outcome based on methods while there is no "OR" relationship is not possible or very strange / difficult.

3: ------------------

People present at last Friday call have seen my proposal for a framework structure based on User Needs / User Functions and User Outcomes and as an example I've been busy with merging Error Prevention / Instructions provided.

The results for the Outcomes is the following:

4: ------------------

Spreadsheet info available at row 43/44:

User Need / (= Guideline): => Users get instructions for interaction

User Outcomes:

- Provide editorial instructions for complete tasks

- Provide format instructions for completing inputs (example: mm/dd/yyyy)

- Provide conditional instructions (example: required, dimmed, etc.)

- Provide identifiable attributes (example: purpose / icons)

- Instructions are present when needed (example: persistent or appear, in the viewport?!)

- Instructions are connected to UIC (example: proximity, programmatic relationship, editorial text?)

User Functions: => Each outcome might be applicable to one of the User Functions defined IF there's an imbalance in accessibility for that function (like the SC Acceptance Criteria).

The formula is: User needs <-- intersection --> User Function = User Outcome (requirements)

5: ------------------

The methods are not worked out but this work can be done later, just like we do with techniques in WCAG 2.x

Janina Sajka Agree I think it important to publish good work, even if it's not the eventual language we think we will adopt
when we finalize and take WCAG 3 through the CR/PR/TR process. So, I favor this publication
because it moves us forward in a good way.
Michael Gower I'm getting a 404 on the Error Prevention Guideline link.

I'm concerned with the method 'Instructions for completing tasks' including the following example: "Providing simple instructions within labels". Typically labels that include instructions are wordy and often counterproductive. The example you give "(required)" is not so much an instruction as an indicator. If this is specifically meant to address required inputs, why not make it something like "Identifying inputs that must be completed"

I'm not sure the User need section is really addressing in the way intended? I thought they were supposed to align with Functional needs?

I don't think your test procedure really captures checking for Required fields.

Okay, so given there is a separate method for required inputs, why is that appearing in the prior input? Removing references to required inputs from instructions resolves most of my prior concerns.

I think there are 2 scenarios that are legitimate ways to meet this which don't align with some of your guidance. They are: 1) Scenario: all fields are required. Solution: "All questions must be answered" is stated once at the start of the form. Fields are still programmatically marked as required, but no additional visual indicator is provided. 2) Almost all fields are required.Solution: "Responses are required, except where noted." appears at top of form. Fields that are not required are marked "(optional)"


"Instructions provided using the placeholder attribute are not persistent and therefore do not meet this requirement." I was a little surprised by this, which appears in the Detailed description section, because I didn't think a Method was considered a "requirement". It also seemed a little technology specific. Finally, I think it needs the word "only" as in "Instructions provided using only the placeholder..."
Bruce Bailey Agree
Jeanne F Spellman Agree
