Kanban

A method for managing and improving the flow of work using a visual board, explicit policies, and limits on work in progress, so that delivery becomes more predictable and bottlenecks become visible.

Related: Kanban Board, Work in Progress Limit, Flow
Kanban Board

A visual representation of the workflow in which work items are shown as cards moving through columns that represent process stages, making status, blockers, and queues easy to see.

Related: Card, Column, Kanban
Card

A single work item shown on a Kanban board, typically carrying information such as its type, age, owner, and blockers, and moved across columns as it progresses.

Related: Kanban Board, Work Item, Lead Time
Column

A vertical lane on a Kanban board representing one stage of the workflow or a queue between stages, used to show where each work item currently sits.

Related: Kanban Board, Workflow, Queue
Work Item

Any unit of value flowing through the system, such as a feature, defect, request, or service ticket, tracked from the moment it enters the workflow until it is delivered.

Related: Card, Work in Progress, Throughput
Workflow

The sequence of stages and activities that work passes through from initial request to delivery, including handoffs, queues, and decision points that shape how quickly value is created.

Related: Value Stream, Column, Kanban Board
Value Stream

The end-to-end set of activities, from customer request to delivery, that creates value for the customer, used to identify delays and waste outside a single team's workflow.

Related: Workflow, Lead Time, Flow
Work in Progress

Work that has been started but not yet finished, including items being actively worked on and items waiting in queues within the workflow.

Related: Work in Progress Limit, Little's Law, Queue
Work in Progress Limit

A maximum number of items allowed in a workflow stage or across the whole system at one time, used to expose bottlenecks, reduce multitasking, and improve flow.

Related: Work in Progress, Pull System, Bottleneck
Pull System

A way of working in which new work is started only when capacity becomes available downstream, rather than being pushed into the system regardless of whether it can be handled.

Related: Work in Progress Limit, Push System, Flow
Push System

A way of working in which work is assigned or released into the next stage according to a plan or schedule, regardless of whether downstream capacity is available, often creating queues.

Related: Pull System, Queue, Work in Progress
Flow

The smooth and continuous movement of work through the workflow with minimal waiting, rework, or handoffs, so that items move steadily toward delivery.

Related: Work in Progress Limit, Bottleneck, Little's Law
Bottleneck

The stage in a workflow that limits the overall rate of delivery because its capacity is lower than the demand placed on it, causing queues to build up in front of it.

Related: Constraint, Queue, Flow
Constraint

Any factor that limits the system from achieving more of its goal, most commonly the capacity of a particular stage, policy, or skill set within the workflow.

Related: Bottleneck, Theory of Constraints, Flow
Theory of Constraints

An improvement approach holding that every system has at least one limiting constraint, and that improvement efforts should focus on identifying and exploiting that constraint before raising capacity elsewhere.

Related: Constraint, Bottleneck, Improvement
Queue

A collection of work items waiting to be processed by the next stage, which adds to lead time without adding value and therefore deserves explicit visibility and management.

Related: Work in Progress, Lead Time, Bottleneck
Lead Time

The total elapsed time from the moment a work item is requested or enters the system until it is delivered to the customer, including all waiting and processing time.

Related: Cycle Time, Little's Law, Throughput
Cycle Time

The elapsed time from when work actively starts on an item until it is finished, excluding time spent waiting before work began.

Related: Lead Time, Throughput, Flow
Throughput

The number of work items completed per unit of time, used as a measure of how much value the system delivers and as an input to forecasting.

Related: Little's Law, Cycle Time, Flow
Little's Law

A mathematical relationship stating that average work in progress equals average throughput multiplied by average lead time, useful for predicting how limiting work affects delivery time.

Related: Work in Progress, Throughput, Lead Time
Cumulative Flow Diagram

A chart plotting the number of items in each workflow stage over time, whose band widths reveal work in progress, bottlenecks, and trends in lead time.

Related: Kanban Board, Work in Progress, Bottleneck
Control Chart

A chart of cycle time or lead time per completed item over time, with statistical limits that help distinguish normal variation from unusual signals worth investigating.

Related: Cycle Time, Lead Time, Variability
Variability

The natural fluctuation in arrival of work, processing times, and item sizes, which increases queues and unpredictability unless explicitly managed.

Related: Queue, Control Chart, Flow
Explicit Policies

Written, visible agreements about how work is handled, such as definitions of ready and done, entry criteria, and prioritization rules, so that behavior is consistent and discussable.

Related: Definition of Done, Kanban Board, Classes of Service
Definition of Done

An agreed checklist describing what must be true for a work item to be considered complete, helping prevent items from lingering unfinished or being handed on prematurely.

Related: Explicit Policies, Workflow, Quality
Classes of Service

Explicit categories of work, such as expedited, fixed date, standard, and intangible, each with its own policies for prioritization and handling so that urgency is managed transparently.

Related: Explicit Policies, Prioritization, Service Level Expectation
Service Level Expectation

A stated probability, based on historical data, that a work item will be completed within a given number of days, used to set realistic expectations with customers.

Related: Cycle Time, Classes of Service, Forecasting
Forecasting

Using historical throughput and cycle time data, often through Monte Carlo simulation, to predict how many items can be delivered by a given date or when a given item will finish.

Related: Throughput, Service Level Expectation, Cycle Time
Kanban System

The complete set of practices, board, policies, limits, and feedback loops that an organization uses to visualize work and manage flow in a given context.

Related: Kanban Board, Explicit Policies, Work in Progress Limit
STATIK

A structured approach for introducing Kanban that starts from understanding demand, capability, and sources of dissatisfaction, then designs a board and limits that fit the actual work.

Related: Kanban System, Work in Progress Limit, Value Stream
Change Management

The way a Kanban adoption is introduced and sustained, including starting with what exists, gaining agreement, and evolving the system incrementally rather than imposing a fixed model.

Related: STATIK, Improvement, Kanban System
Improvement

The deliberate, ongoing effort to raise the capability of the workflow by removing bottlenecks, adjusting policies and limits, and reducing delays, guided by data from the board.

Related: Constraint, Variability, Kanban System
Feedback Loop

A recurring review, such as a daily standup or service delivery review, in which the team examines flow data and policies and decides on adjustments to the Kanban system.

Related: Improvement, Cumulative Flow Diagram, Explicit Policies
Blocker

Anything preventing a work item from progressing, which should be made visible on the board, such as with a flag, so it can be resolved quickly.

Related: Card, Explicit Policies, Flow
Aging

The amount of time a work item has spent in its current stage, often shown on cards, used to spot items that are stalled and to prompt action before they breach expectations.

Related: Card, Cycle Time, Blocker
Swarming

A practice in which team members collaborate on a single item, often one at a bottleneck, rather than each starting new work, to finish items faster and reduce work in progress.

Related: Work in Progress Limit, Bottleneck, Flow
Definition of Ready

Agreed criteria that a work item must meet before it may enter a workflow stage, protecting downstream stages from unclear or incomplete input.

Related: Explicit Policies, Definition of Done, Workflow
Kanban Maturity

A staged view of how deeply an organization has embedded Kanban practices, from basic visualization and limits toward enterprise-wide flow optimization and customer-focused service delivery.
