Use human approval gate for pausing AI or automation before a high-impact step can run; approval workflow for routed request approval over time; review queue for triaging many items; review before submit for a requester's final editable check; and recommended next action for optional context-sensitive guidance.

Human approval gate

Use it when: An AI agent, workflow, deployment, or automation is ready to perform a high-impact step and must pause for human authorization.

Make this state clear: Paused gate state with proposed action, payload snapshot, reason for gate, and run context.

Observe the result: A billing lead opens the paused refund gate, sees that the amount is under policy but source grounding is partial, edits the refund to the verified amount, approves, and the agent resumes only that step.

Approval workflow

Use it when: A submitted request needs authorized approval before a deployment, purchase, access grant, publication, content change, policy exception, financial action, or workflow step can proceed.

Make this state clear: Draft or submit-ready request handoff state

Observe the result: A finance approval requires both manager and controller approval; the first approval advances the sequence, a rejection stops downstream processing, and the requester sees the exact rejection reason and revise action.

Study the full pattern →

Review queue

Use it when: A team or individual repeatedly reviews many independently queued items.

Make this state clear: Queue loading and count state

Observe the result: A reviewer claims the oldest SLA-at-risk ticket, opens a preview, assigns it to Billing, returns to the queue with the row removed, and lands on the next oldest item.

Study the full pattern →

Review before submit

Use it when: A user has provided multiple answers and should verify them before a consequential submit action.

Make this state clear: Initial review state with grouped captured answers, relevant sections, and explicit submit action.

Observe the result: A user changes their phone number from review, lands on the phone page with the old value pre-filled, saves, and returns directly to review with other answers preserved.

Study the full pattern →

Recommended next action

Use it when: Users are working in a record, case, conversation, or workflow where choosing the next action is costly or error-prone.

Make this state clear: Recommended action state with action title, reason, evidence, trigger, consequence, and accept or review path.

Observe the result: A representative reviews the suggested reply, sees that it was triggered by customer intent and a matching knowledge article, edits the draft, and sends it.

Practice the judgment: Imagine this situation: Automation says waiting for approval but hides the exact tool call, payload, risk, approver, or resume behavior. Write the person's goal, choose one of these patterns, and show the state that helps the person continue. Use the decision rules and source trail below to explain your choice.

UI guidance Render a human approval gate as a paused automation checkpoint with the proposed action, tool or workflow step, triggering rule, risk level, payload snapshot, requester or agent, approver eligibility, timeout, and explicit approve, reject, edit, cancel, or bypass controls.Render approval workflow as a routed request record with requester, object, requested action, approver eligibility, required rule, current gate, due date, decision controls, comment history, and outcome consequences.Render review queue as an actionable worklist with queue scope, counts, filters, sort order, row reason, owner, priority, age or SLA, status, preview context, selection, and row actions.Render a single review page immediately before commit with a clear title, grouped answer sections, readable key/value rows, per-answer or per-section Change actions, skipped optional answers when meaningful, and a primary button whose label names the committed action.Render the recommended next action as a bounded suggestion card or action slot that names the action, trigger context, expected outcome, owner, due time or urgency, eligibility status, and why the system is suggesting it now.
UX guidance Use human approval gate when automation is ready to act but policy, risk, confidence, cost, access, publication, deployment, customer impact, or legal consequence requires a human decision before execution continues.Make the approval route understandable over time: who has the request, what decision is needed, what happens on approval or rejection, what blocks self-review, and where the requester can revise or withdraw.Use review queue when a team repeatedly processes a changing set of tickets, comments, pull requests, content items, cases, requests, or records that require human inspection and action.Use review before submit to give users one final chance to verify and correct captured answers before a transaction is sent, paid, published, applied, or otherwise committed.Keep recommended next action separate from broad recommendations, task lists, primary buttons, assignments, approvals, and review queues because it is optional, contextual, explainable, and directly tied to the current work state.
Good UI An AI support agent pauses before issuing a refund, shows the proposed amount, customer, policy match, confidence, source grounding, approver role, timeout, Approve refund, Edit amount, Reject, and Stop run controls.A production deployment request shows requester, service, environment, change summary, required reviewer group, self-review restriction, wait timer, Approve and Reject with reason controls, and a timeline of route changes.A moderation queue has Held, Likely spam, Reported, and Escalated tabs, row evidence, policy reason, reviewer claim state, approve/remove/escalate actions, and bulk-action preview.A claim review page has Applicant, Contact details, Evidence, and Declaration sections; each row shows the captured answer and a Change link with hidden context such as Change email address.A support case sidebar recommends Send refund-policy article because the customer asked about a refund twice, shows confidence, source snippets, and opens a draft for review.
Bad UI A reviewer can approve an automation run after the action already executed, making the gate only decorative audit text.A stale email approval applies to a request version that has changed.The most urgent or oldest item is buried by default sort.Change links lack context, so assistive technology users hear a list of identical Change links.Required onboarding tasks and optional suggestions are mixed in one list labelled Next best actions.

Human approval gate

UI or UX
UI + UX - Runtime checkpoint that pauses AI or automation until an eligible human authorizes the next step
UI guidance
Render a human approval gate as a paused automation checkpoint with the proposed action, tool or workflow step, triggering rule, risk level, payload snapshot, requester or agent, approver eligibility, timeout, and explicit approve, reject, edit, cancel, or bypass controls.
UX guidance
Use human approval gate when automation is ready to act but policy, risk, confidence, cost, access, publication, deployment, customer impact, or legal consequence requires a human decision before execution continues.
Good UI
An AI support agent pauses before issuing a refund, shows the proposed amount, customer, policy match, confidence, source grounding, approver role, timeout, Approve refund, Edit amount, Reject, and Stop run controls.
Bad UI
A reviewer can approve an automation run after the action already executed, making the gate only decorative audit text.
Good UX
A billing lead opens the paused refund gate, sees that the amount is under policy but source grounding is partial, edits the refund to the verified amount, approves, and the agent resumes only that step.
Bad UX
A human approves a stale agent action from email and the agent applies it to a different customer state.
Best fit
An AI agent, workflow, deployment, or automation is ready to perform a high-impact step and must pause for human authorization.
Avoid when
The action has already happened and users only need an audit log.
Required state
Paused gate state with proposed action, payload snapshot, reason for gate, and run context.
Accessibility burden
Expose gate status, proposed action, target, payload summary, risk, approver rule, timeout, and current run state as text.
Common misuse
Using a post-action audit record as if it were a pre-action human gate.

Approval workflow

UI or UX
UI + UX - Routed decision workflow for requests that require authorized approval
UI guidance
Render approval workflow as a routed request record with requester, object, requested action, approver eligibility, required rule, current gate, due date, decision controls, comment history, and outcome consequences.
UX guidance
Make the approval route understandable over time: who has the request, what decision is needed, what happens on approval or rejection, what blocks self-review, and where the requester can revise or withdraw.
Good UI
A production deployment request shows requester, service, environment, change summary, required reviewer group, self-review restriction, wait timer, Approve and Reject with reason controls, and a timeline of route changes.
Bad UI
A stale email approval applies to a request version that has changed.
Good UX
A finance approval requires both manager and controller approval; the first approval advances the sequence, a rejection stops downstream processing, and the requester sees the exact rejection reason and revise action.
Bad UX
The first approver clicks Approve and the system marks the whole request approved even though policy required everyone to approve.
Best fit
A submitted request needs authorized approval before a deployment, purchase, access grant, publication, content change, policy exception, financial action, or workflow step can proceed.
Avoid when
The user only needs to check their own answers before submission.
Required state
Draft or submit-ready request handoff state
Accessibility burden
Use labelled request summary, approver, status, due date, decision, comment, and history regions.
Common misuse
Treating the first approval as final when the rule requires more approvers.

Review queue

UI or UX
UI + UX - Actionable queue for triaging many items that need human review
UI guidance
Render review queue as an actionable worklist with queue scope, counts, filters, sort order, row reason, owner, priority, age or SLA, status, preview context, selection, and row actions.
UX guidance
Use review queue when a team repeatedly processes a changing set of tickets, comments, pull requests, content items, cases, requests, or records that require human inspection and action.
Good UI
A moderation queue has Held, Likely spam, Reported, and Escalated tabs, row evidence, policy reason, reviewer claim state, approve/remove/escalate actions, and bulk-action preview.
Bad UI
The most urgent or oldest item is buried by default sort.
Good UX
A reviewer claims the oldest SLA-at-risk ticket, opens a preview, assigns it to Billing, returns to the queue with the row removed, and lands on the next oldest item.
Bad UX
A reviewer marks a pull request reviewed from an old queue row after the author pushed new commits and re-requested review.
Best fit
A team or individual repeatedly reviews many independently queued items.
Avoid when
The task is a single request moving through a governed approval route.
Required state
Queue loading and count state
Accessibility burden
Use labelled queue name, count, filters, sort, group, row status, selection, preview, and action controls.
Common misuse
Treating review queue as approval workflow and hiding many-item workload controls.

Review before submit

UI or UX
UI + UX - Final editable answer summary before committing a transaction
UI guidance
Render a single review page immediately before commit with a clear title, grouped answer sections, readable key/value rows, per-answer or per-section Change actions, skipped optional answers when meaningful, and a primary button whose label names the committed action.
UX guidance
Use review before submit to give users one final chance to verify and correct captured answers before a transaction is sent, paid, published, applied, or otherwise committed.
Good UI
A claim review page has Applicant, Contact details, Evidence, and Declaration sections; each row shows the captured answer and a Change link with hidden context such as Change email address.
Bad UI
Change links lack context, so assistive technology users hear a list of identical Change links.
Good UX
A user changes their phone number from review, lands on the phone page with the old value pre-filled, saves, and returns directly to review with other answers preserved.
Bad UX
A user selects Change address, edits one field, then has to repeat every later page before finding the review page again.
Best fit
A user has provided multiple answers and should verify them before a consequential submit action.
Avoid when
The task is a single low-risk field with clear inline validation and an obvious submit action.
Required state
Initial review state with grouped captured answers, relevant sections, and explicit submit action.
Accessibility burden
Use headings that make the review task explicit, such as Check your answers before sending your application.
Common misuse
Labelling the final commit button Continue.

Recommended next action

UI or UX
UI + UX - Context-sensitive workflow action suggested for the user's current record, case, conversation, or task
UI guidance
Render the recommended next action as a bounded suggestion card or action slot that names the action, trigger context, expected outcome, owner, due time or urgency, eligibility status, and why the system is suggesting it now.
UX guidance
Keep recommended next action separate from broad recommendations, task lists, primary buttons, assignments, approvals, and review queues because it is optional, contextual, explainable, and directly tied to the current work state.
Good UI
A support case sidebar recommends Send refund-policy article because the customer asked about a refund twice, shows confidence, source snippets, and opens a draft for review.
Bad UI
Required onboarding tasks and optional suggestions are mixed in one list labelled Next best actions.
Good UX
A representative reviews the suggested reply, sees that it was triggered by customer intent and a matching knowledge article, edits the draft, and sends it.
Bad UX
A user accepts a suggested discount and only afterward learns it changed contract terms.
Best fit
Users are working in a record, case, conversation, or workflow where choosing the next action is costly or error-prone.
Avoid when
The action is always required and should be a task, validation, or workflow gate.
Required state
Recommended action state with action title, reason, evidence, trigger, consequence, and accept or review path.
Accessibility burden
Use a labelled region or card heading that identifies the suggestion as recommended, optional, and scoped to the current work object.
Common misuse
Hiding why the action was suggested, what evidence was used, or what will change.
Decision rules
  • Choose human approval gate when an AI agent, automation, deployment, workflow, or model-driven action must pause at a named checkpoint until an eligible human approves, rejects, edits, or overrides before execution continues.
  • Choose approval workflow when the primary object is a submitted request record moving through one or more approver routes, comments, reassignments, changes, and final outcomes over time.
  • Choose review queue when reviewers triage many independent items, claim rows, preserve queue position, and handle stale rows or bulk scope.
  • Choose review before submit when the same user is checking their own captured answers before committing a form or transaction.
  • Choose recommended next action when the system proposes an optional workflow step; use human approval gate when policy says automation cannot continue without human authorization.
  • A human approval gate must show the paused automation step, proposed action, triggering rule, risk or impact, input snapshot, model or workflow version, approver eligibility, timeout, and what happens on approve, reject, edit, expire, or bypass.
  • Approval at the gate must resume only the gated automation step and must revalidate version, scope, permissions, threshold, and freshness before execution so stale decisions cannot resume unsafe automation.
  • Rejection, edit-before-approve, timeout, bypass, and emergency stop are different gate outcomes and should not collapse into one vague failed automation state.
  • Do not replace the gate with a passive audit log, post-hoc audit, notification, confidence score, or review queue row when the next automated step is still armed.
  • When several approvals are needed over days, use approval workflow around the gate; when one runtime checkpoint blocks an agent or automation run, use human approval gate.

Failure modes
  • Automation says waiting for approval but hides the exact tool call, payload, risk, approver, or resume behavior.
  • A human clicks Approve on an old notification and the agent resumes against a changed input or stale model state.
  • The approval UI lets any viewer approve even though the gate requires a specific role or separation of duties.
  • Rejecting a gate leaves the automation suspended forever with no cancel, revise, retry, or fallback path.
  • A review queue row marks an item reviewed but the actual armed automation step remains unclear.
  • The system logs a human approval after the action has already run, turning the gate into post-hoc audit and allowing stale decisions to look valid.
