| UI guidance | Render version history as a durable snapshot browser with the current version, previous version list, author, timestamp, named version labels, autosaved version labels, changed summary, retention status, compare affordance, preview, and restore action. | Render activity logs as evidence-oriented records with event time, actor, action, object, source system, scope, result, and technical context such as IP address or location when available. | Render the timeline as a labelled chronological sequence where each event has a visible date or time, event title, actor or system source when known, status or type, and a short summary. | Show a named recovery affordance after the completed action, such as Undo delete for a specific task, near the result or in a consistent status region. | Label the current version explicitly as Draft, Unpublished changes, Published, Active, Locked, or Unavailable, and place that label near the object title, list row, editor header, and publish actions. | Render publish workflow as a readiness and release surface with content identity, current status, target destination, affected pages or entries, preview, validation, permission, schedule, publish, unpublish, rollback, and live verification. | Render comments as anchored contributions with author identity, timestamp, body, optional attachment or selection context, edited state, reply target, and state labels such as open, resolved, hidden, deleted, or assigned. | Show the blocked object or action, current account, permission level, required role, owner, and request path when revealing that information is allowed. |
| UX guidance | Use version history when users need to find a known good state, understand what changed between saved states, recover from bad edits, cite a prior version, name a meaningful milestone, or restore content without guessing. | Use activity log when users need to investigate, audit, verify, or troubleshoot actions across accounts, objects, systems, settings, or security boundaries. | Use timeline when users need to understand what happened, where they are now, and what may happen next in a case, claim, application, order, incident, or process. | Let users move quickly through frequent reversible actions, then recover from mistakes after seeing the result. | Use draft state when users need to pause work on an object, return later, and decide whether to publish, activate, discard, or keep editing an unpublished version. | Use publish workflow when a user is moving content, product data, site changes, configuration, release notes, or campaign material from draft, staged, scheduled, or approved state to a selected live or public target. | Use comments when users need to discuss, question, annotate, review, or leave follow-up notes on a specific object, selection, file line, record, document, or task without changing the primary content directly. | Use permission denied state when the system knows the user is authenticated but their role, group, share, license, policy, or approval status blocks a specific object or action. |
| Good UI | A document side panel marks v42 as Current, lists v41, v38 named Pre-launch copy, and v35 autosaved, and opens a compare preview before Restore this version. | An organization audit log table shows timestamp, actor, action, target object, app, IP address, result, and a Details drawer with before and after fields. | A benefits application timeline groups events by date and shows Application submitted, Evidence requested, Evidence received, Decision pending, and Next review, with actor, timestamp, and status marker. | Deleting Quarterly report removes it from the list and shows a recovery panel saying Quarterly report deleted with an Undo task button. | A knowledge article header says Draft saved today, shows the currently published title, and offers Resume draft, Compare with published, Discard draft, and Publish. | A CMS publish panel shows Draft article, production site, English and French locales, validation complete, preview URL, scheduled time, affected entries, and actions to Publish now, Schedule, or Keep draft. | A document margin comment shows the selected paragraph, author, timestamp, body text, Reply, Resolve, Assign, and Copy link actions with the composer focused on that selection. | A report page says Quarterly revenue report requires Finance viewer access, shows the current account, names the report owner, and offers Request access and Switch account. |
| Bad UI | A History panel lists Edited, Edited, Edited with no version number, author, content preview, compare result, or restore consequence. | A page titled Activity shows vague entries such as Changed settings with no actor, target, timestamp, or source. | A vertical line lists Approved, More, Update, and Done with no dates, actors, status, or explanation. | A tiny x removes an item with no object-specific recovery label. | An editor opens directly into draft text but the header only says Saved, so users cannot tell whether viewers see the changes. | A Publish button sends changes live to every domain with no staging/production target, preview, validation, or affected-page list. | A Notes textarea sits under a record and calls itself comments even though every user overwrites the same field. | A denial page says Something went wrong and shows Retry even though the user lacks a required group. |
| Good UX | A designer names the last approved file version, compares it against the current version, confirms restore, and sees that the restore created v43 while keeping v42 available. | An admin filters to failed SSO events, expands one entry, copies the event ID, exports the filtered range, and sees that records older than 180 days require a different archive. | A caseworker filters the timeline to System events, sees two date groups hidden, restores all events, and the event order and current marker stay stable. | Undo restores the deleted task to the list and reports Quarterly report restored. | A user opens a published article that has an unpublished version, chooses Resume draft, reviews a change summary, publishes, and sees the page become visible to viewers. | A content editor previews a campaign page, fixes a missing hero image, schedules publication and retirement times, sees the job queued, and later verifies the live URL and scheduled unpublish state. | A reviewer comments on a selected line, adds an action item for Dana, receives a reply, resolves the comment, and can reopen it from the resolved filter. | A user opens a restricted report, sees which account is signed in, requests viewer access with a reason, then sees that the request is pending with the owner. |
| Bad UX | A user tries to recover yesterday's copy but only sees a chronological activity log with no previewable previous version. | A user marks a notification read and the corresponding activity evidence disappears from the only log. | A user sees a future appointment marker styled like completed history and assumes the appointment already happened. | A second delete overwrites the first recoverable item without explaining which action Undo affects. | A user closes an editor after seeing Saved, later discovers the page was never published, and cannot find the draft in the content list. | A user clicks Save and assumes the page is live because the interface uses Save, Submit, Schedule, and Publish interchangeably. | A user writes a long comment, loses network connection, and the draft disappears when the page reloads. | The app returns a blank screen for a restricted file, so the user cannot tell whether the file is gone, private, or opened with the wrong account. |
| Best fit | Users edit documents, files, pages, design files, records, configurations, or published content over time. | Users need to inspect recorded user, admin, system, security, or integration events. | Users need a chronological record of important events for one object, case, order, application, or process. | The action is common and mistakes are likely. | Users create or edit objects that should not become visible, active, submitted, or externally effective until a later action. | Users need to make content, products, pages, releases, site changes, campaigns, or configuration visible to an audience. | Users need object-attached discussion without changing the primary object content directly. | A signed-in user lacks permission to view, edit, publish, export, delete, approve, share, administer, or configure a resource. |
| Avoid when | The product only has an event log with no saved content snapshots. | The goal is only to show a readable milestone history for one case or process. | The surface is a live stream whose content keeps arriving and must preserve reader position. | The action has external side effects that cannot be recalled. | The change is a small one-field edit that should be saved or canceled immediately. | The user is only saving unfinished work. | The user is simply entering a long answer into a form field. | The user is not signed in and the next step is authentication rather than authorization. |
| Required state | Default state with current version, previous version list, author, timestamp, and change summary. | Default log state with event records, result count, visible timezone, retention window, and permission scope. | Default timeline with heading, order label, date or phase groups, and event markers. | Normal state before the user action. | Published or active state with no draft. | Draft or edited but unpublished state | Empty comment list and first-comment composer. | Whole-object access denied state. |
| Accessibility burden | Use structured list, table, or tab semantics so version number, current status, author, timestamp, and label are read together. | Use table or structured list semantics so actor, action, object, timestamp, result, and scope are perceivable together. | Use semantic list or ordered-list structure with date-group headings and text event labels. | Make the undo control keyboard reachable and programmatically identifiable. | Expose Draft, Published, Unpublished changes, Locked, and Unavailable as text in the page title area and list rows, not only by color or icon. | Use labelled controls for status, target, preview, schedule date and time, timezone, validation, publish, unpublish, rollback, and live URL. | Label the comments region with the object or selection being discussed. | Use a heading that identifies the access boundary and a text description that does not rely on lock icons or red color alone. |
| Common misuse | Calling an activity log or audit trail version history when it has no previous content snapshots. | Calling a social feed or notification drawer an activity log without event evidence. | Using timeline as decorative chrome around a normal list with no meaningful time sequence. | Offering undo for an action that cannot actually be reversed. | Using Saved to mean both saved draft and published content. | Using Save, Submit, Schedule, and Publish interchangeably. | Using one shared Notes field as a comment system and overwriting prior contributors. | Treating authorization denial as a generic retryable error. |
