Trello – Visual Project Management & Kanban Boards

What is Trello?

Trello has become synonymous with visual project management, offering an intuitive kanban-style interface that transforms how individuals and teams organize work, track progress, and collaborate on projects of any scale. Since its launch, Trello’s deceptively simple board-and-card system has attracted millions of users who discovered that dragging cards across columns provides a more natural and satisfying way to manage tasks than traditional to-do lists or complex project management software.

The application’s genius lies in its flexibility. While Trello provides structure through boards, lists, and cards, it imposes minimal constraints on how users employ these elements. A board might track a software development sprint, plan a wedding, manage a content calendar, or organize a home renovation. The same fundamental mechanics adapt to virtually any workflow, which explains Trello’s adoption across industries, team sizes, and use cases.

Core Concepts

Understanding Trello’s building blocks unlocks its organizational potential.

Boards

Boards serve as top-level containers representing projects, workflows, or any collection of related work. Each board provides an independent workspace with its own lists, cards, members, and settings.

Board backgrounds customize visual identity through colors, images, or custom uploads. This personalization helps distinguish different projects at a glance and can reinforce team or project branding.

Board visibility controls determine who can see and access content. Private boards restrict access to invited members, workspace-visible boards open to all workspace members, and public boards allow anyone to view content.

Lists

Lists organize cards into vertical columns representing stages, categories, or any grouping meaningful to the workflow. The classic kanban approach uses lists like “To Do,” “In Progress,” and “Done,” but users create whatever structure suits their needs.

Lists can be reordered by dragging, enabling workflow adjustments as processes evolve. Copying lists duplicates entire column structures for recurring workflows.

List actions include archiving completed work, moving all cards, and sorting cards by various criteria.

Cards

Cards represent individual items—tasks, ideas, issues, or any discrete unit of work. Cards move between lists by dragging, visually representing progress through workflow stages.

Card fronts display titles and key information like due dates, labels, and member assignments. Opening cards reveals full details including descriptions, checklists, attachments, comments, and activity history.

Cards can be copied, moved between boards, archived, or converted to templates for recurring item types.

Card Features

Cards contain rich functionality beyond simple task representation.

Descriptions

Markdown-formatted descriptions provide detailed information about card contents. Links, formatting, and embedded content create comprehensive documentation within cards.

Descriptions serve as the primary location for requirements, specifications, meeting notes, or any context needed to understand and complete the work.

Checklists

Checklists break cards into subtasks with completion tracking. Progress bars show checklist completion percentage on card fronts, providing quick status visibility.

Multiple checklists per card enable organizing subtasks into categories. Checklist templates save common item sets for reuse across cards.

Labels

Color-coded labels tag cards with categories, priorities, or any classification scheme. Labels appear on card fronts, enabling visual scanning for specific types across boards.

Custom label names clarify meanings beyond color alone. Filtering by labels shows only matching cards, focusing attention on specific categories.

Due Dates

Due dates establish deadlines with optional reminder notifications. Cards approaching or past due dates display visual warnings, preventing overlooked deadlines.

Start dates complement due dates for time-boxed work. Calendar views display cards by date, revealing schedule patterns and conflicts.

Attachments

File attachments store relevant documents directly on cards. Cloud service integrations attach files from Google Drive, Dropbox, OneDrive, and other sources without downloading and re-uploading.

Cover images display selected attachments as card backgrounds, adding visual identification beyond text titles.

Comments

Comment threads enable discussion within card context. Mentions notify specific members about relevant comments. Emoji reactions provide quick feedback without full replies.

Activity feeds record all card changes, creating audit trails of who changed what and when.

Collaboration Features

Trello facilitates team collaboration through shared workspaces and communication tools.

Member Assignment

Assigning members to cards establishes responsibility and filters cards by assignee. Member avatars on card fronts show ownership at a glance.

Multiple members per card support shared responsibilities or team awareness. Assignment notifications alert members to new responsibilities.

Workspaces

Workspaces (formerly Teams) group related boards and members into organizational units. Workspace-level settings control permissions, visibility defaults, and available Power-Ups.

Members join workspaces with various permission levels from observers through administrators. Permission tiers balance access needs with security requirements.

Activity Notifications

Configurable notifications alert members to relevant board activity. Notification preferences balance staying informed against notification overload.

Watching boards, lists, or cards subscribes to updates on specific content. Watch settings enable focused attention on priority items.

Power-Ups

Power-Ups extend Trello’s functionality through integrations and feature additions.

Built-in Power-Ups

Calendar view displays cards with due dates in calendar format. Map view shows cards with location data geographically. Custom fields add structured data beyond Trello’s standard properties.

Dashboard view aggregates board statistics and charts. Card repeater automates recurring card creation.

Integration Power-Ups

Slack integration posts Trello activity to channels and creates cards from messages. Google Drive attachment integration browses and attaches files without leaving Trello.

Jira integration links cards to Jira issues for teams using both tools. GitHub and GitLab integrations connect cards to code repositories and pull requests.

Automation Power-Ups

Butler automation creates rules, scheduled commands, and buttons that automate repetitive actions. When cards move, Butler can update fields, add comments, or trigger additional actions automatically.

Third-party automation through Zapier, Make, or similar platforms connects Trello to hundreds of additional services.

Butler Automation

Butler deserves special attention as Trello’s built-in automation engine.

Rules

Rules trigger actions automatically when specified conditions occur. Moving a card to the “Done” list might mark due dates complete and add a completion comment.

Rule triggers include card movements, due date arrivals, label changes, checklist completions, and numerous other events. Actions span the full range of Trello operations.

Scheduled Commands

Scheduled commands execute at specified times—daily, weekly, or on custom schedules. Automatic archiving of old cards, report generation, or periodic card creation run without manual intervention.

Card and Board Buttons

Custom buttons execute multiple actions with single clicks. A “Start Working” button might move a card, assign the current user, set a due date, and add a checklist simultaneously.

Board buttons apply actions across multiple cards matching criteria. Bulk operations that would require many clicks become single-button actions.

Views

Multiple view options present board content in different formats.

Board View

The classic board view displays lists as columns with cards as draggable items. This primary interface suits active work management and quick status updates.

Timeline View

Timeline view displays cards as bars across a time axis, visualizing schedules and dependencies. This Gantt-style presentation suits project planning and deadline management.

Table View

Table view presents cards as spreadsheet rows with properties as columns. Sorting, filtering, and bulk editing suit data-heavy workflows and reporting needs.

Calendar View

Calendar view shows cards with due dates in day, week, or month formats. Date-based planning and schedule visualization benefit from this temporal presentation.

Dashboard View

Dashboard view aggregates board statistics into charts and widgets. Status overviews, completion trends, and member workloads appear in visual summaries.

Mobile Applications

Mobile apps extend Trello access to smartphones and tablets.

Full Functionality

iOS and Android applications provide complete Trello functionality adapted for touch interfaces. Board management, card editing, and collaboration work seamlessly on mobile devices.
