# Concepts

> This section explains the core ideas behind Nextedy PLANNINGBOARD — how it models Plans and work items as cards, how swimlanes organize the board, and how capacity tracking and prioritization support planning decisions.

## Board structure and Plans

[**Introduction to Planningboard**](/planningboard/concepts/introduction) — What the board is, how it fits into Polarion, and the relationship between Plans and the board view.

[**Board Structure**](/planningboard/concepts/board-structure) — The anatomy of the board: swimlanes, cards, columns, and how work items and Plans appear on the board surface.

[**Plans Modes**](/planningboard/concepts/plans-modes) — How the board selects and displays Plans using a Plan query, and the different modes in which Plans can be presented.

## Swimlanes

[**Swimlane Assignment Modes**](/planningboard/concepts/assignment-modes) — The available swimlane assignment types that control how work items are grouped into swimlane rows.

## Capacity

[**Capacity Tracking**](/planningboard/concepts/capacity-tracking) — How the capacity bar reflects effort against available capacity per swimlane, and how the board surfaces overloaded and underloaded swimlanes.

[**Normalization**](/planningboard/concepts/normalization) — How capacity normalization adjusts effort values so that swimlanes with different team sizes or sprint lengths can be compared consistently.

## Planning workflows

[**Prioritization**](/planningboard/concepts/prioritization) — How the board's ordering mechanism controls the priority of work items within and across swimlanes.

[**Dependencies and Links**](/planningboard/concepts/dependencies) — How work-item link roles surface as dependency indicators on cards.

[**SAFe Integration**](/planningboard/concepts/safe-integration) — How Planningboard supports Scaled Agile Framework planning structures within Polarion.

[**Teams Service**](/planningboard/concepts/teams-service) — How the Teams Service provides team membership and capacity data consumed by the board.

<Tip>
  If you are new to Planningboard, read [Introduction to Planningboard](/planningboard/concepts/introduction) first, then [Board Structure](/planningboard/concepts/board-structure). For capacity planning, continue with [Capacity Tracking](/planningboard/concepts/capacity-tracking) and [Normalization](/planningboard/concepts/normalization).
