Foundations of Kanban

Origins in Toyota’s manufacturing system

The Kanban system originated in Toyota’s manufacturing plants during the late 1940s. Taiichi Ohno, an industrial engineer, developed this method to optimise production efficiency. The system was inspired by supermarket restocking practices, where items are replenished only when needed.

Adaptation to software development and other industries

In the early 2000s, software development teams began adopting Kanban principles. David J. Anderson pioneered this adaptation, applying Kanban to knowledge work. Since then, various industries have embraced Kanban for its versatility and effectiveness in managing workflows.

Core principles of Kanban

Kanban is built on six fundamental principles:

1. Visualise the workflow: Create a visual representation of your work process using a Kanban board. This provides a clear overview of task progression and bottlenecks.
2. Limit work in progress (WIP): Set maximum limits for tasks in each workflow stage. This prevents overloading and improves focus and efficiency.
3. Manage flow: Monitor and optimise the smooth movement of work items through the system. Identify and address bottlenecks promptly.
4. Make process policies explicit: Clearly define and communicate rules and guidelines for how work should progress through the system.
5. Implement feedback loops: Establish regular review points to gather insights and make data-driven improvements to the workflow.
6. Improve collaboratively: Encourage team members to work together in identifying and implementing process enhancements continually.

By adhering to these principles, teams can create a flexible and efficient workflow management system. Kanban’s adaptability allows for gradual improvements without disrupting existing processes, making it an attractive option for various organisations.

Key components of a Kanban system

Kanban board

The Kanban board is the central element of any Kanban system. It provides a visual representation of your team’s workflow and task progress.

Physical vs digital boards

Teams can choose between physical and digital Kanban boards:

• Physical boards: Often use whiteboards or large wall spaces with sticky notes representing tasks.
• Digital boards: Utilise software platforms that offer virtual Kanban boards accessible from anywhere.

Both types have their merits, and the choice depends on team preferences and work environment.

Columns and workflow stages

Kanban boards are divided into columns representing different stages of work. A basic board might include:

• To Do
• In Progress
• Review
• Done.

Teams can customise these columns to reflect their specific workflow stages.

Kanban cards

Kanban cards represent individual work items or tasks on the board.

Purpose and information included

Each card typically contains:

• Task description
• Assignee
• Due date
• Priority level
• Additional relevant details.

This information helps team members quickly understand task requirements and status.

Movement through the workflow

As work progresses, team members move cards across the board’s columns. This visual movement allows for easy tracking of task progress and identification of bottlenecks.

Work in Progress (WIP) limits

WIP limits are crucial for maintaining an efficient workflow.

Definition and importance

WIP limits set the maximum number of tasks allowed in each workflow stage. They prevent overloading and encourage focus on completing current tasks before starting new ones.

Setting and adjusting WIP limits

To determine appropriate WIP limits:

• Start with a reasonable estimate based on team capacity.
• Monitor workflow and adjust limits as needed.
• Regularly review and optimise limits to improve efficiency.

Swimlanes and classes of service

Swimlanes and classes of service add another dimension to Kanban boards, enhancing organisation and prioritisation.

Purpose and implementation

Swimlanes are horizontal divisions on the board that can represent:

• Different projects
• Team members or departments
• Types of work

Classes of service categorise work items based on their urgency or impact:

• Expedite: Highest priority, bypass normal flow
• Fixed date: Time-sensitive items
• Standard: Regular work items
• Intangible: Low priority or improvement tasks.

Prioritisation and workflow management

Implementing swimlanes and classes of service helps teams:

• Visualise workload distribution
• Prioritise tasks effectively
• Manage different types of work simultaneously
• Ensure critical items receive appropriate attention.

By utilising these key components, teams can create a comprehensive Kanban system that promotes transparency, efficiency, and continuous improvement in their workflow management.

Implementing Kanban in project management

Getting started with Kanban

Implementing Kanban in project management begins with a thorough understanding of your current processes.

Mapping the current workflow

1. Gather your team to discuss the existing workflow.
2. Identify all stages a task goes through from inception to completion.
3. Document these stages and their sequence.

This exercise provides a clear picture of how work currently flows through your team.

Identifying bottlenecks and inefficiencies

With your workflow mapped, analyse it for:

• Bottlenecks: Stages where work consistently piles up.
• Inefficiencies: Unnecessary steps or redundant processes.
• Delays: Points where work often stalls.

Identifying these issues helps prioritise areas for improvement in your Kanban implementation.

Creating a Kanban board

The Kanban board is the visual representation of your workflow.

Choosing the right tool (physical or digital)

Consider these factors when selecting between physical and digital boards:

Benefits of Kanban project management

Implementing Kanban in project management offers numerous advantages that can significantly enhance team performance and project outcomes.

• The system evolves with the team’s needs and project requirements.

Reduced cycle times and faster delivery

By optimising workflow and reducing waste, Kanban can:

• Shorten the time from task initiation to completion
• Enable faster feedback loops and iterative improvements
• Facilitate quicker delivery of value to customers or stakeholders.

The benefits of Kanban extend beyond these key areas. Teams often report improved job satisfaction, reduced stress, and better-quality outputs. As organisations become more proficient with Kanban, they may see improvements in predictability, risk management, and overall project success rates.

Kanban metrics and analytics

Effective use of Kanban relies on data-driven decision-making. Key metrics and analytics tools help teams monitor performance and identify areas for improvement.

Cycle time

Cycle time measures the duration from when work begins on an item until it’s completed. This metric helps teams:

• Understand how long tasks typically take
• Identify process bottlenecks
• Set realistic expectations for task completion.

To calculate cycle time, track the time each task spends in the “In Progress” column.

Lead time

Lead time is the total time from when a task is requested to when it’s delivered. It includes both waiting time and cycle time. Lead time helps:

• Manage customer expectations
• Identify delays in starting work on new items
• Improve overall process efficiency.

Throughput

Throughput measures the number of items completed in a given time period. This metric provides insights into:

• Team productivity
• Capacity planning
• Identifying trends in work completion rates.

Track throughput weekly or monthly to gauge team performance over time.

Cumulative flow diagrams

Cumulative flow diagrams (CFDs) visually represent the status of tasks over time. They help teams:

• Identify bottlenecks and constraints
• Visualise work in progress (WIP) levels
• Understand how work flows through the system.

CFDs show the number of items in each workflow stage, with time on the x-axis and number of items on the y-axis.

Control charts

Control charts track cycle times for individual items and display them over time. They help teams:

• Identify outliers in task completion times
• Understand process stability
• Predict future performance.

Upper and lower control limits on these charts indicate expected cycle time ranges.

By regularly analysing these metrics, teams can gain valuable insights into their Kanban process. This data-driven approach enables continuous improvement and helps teams optimise their workflow for maximum efficiency and productivity.

Comparing Kanban to other project management methodologies

Understanding how Kanban differs from other methodologies can help teams choose the best approach for their needs.

Kanban vs Scrum

While both Kanban and Scrum are Agile methodologies, they have distinct differences:

Kanban offers more flexibility, while Scrum provides a structured framework with regular intervals.

Kanban vs traditional project management

Traditional project management, often associated with the Waterfall model, differs significantly from Kanban:

• Kanban focuses on continuous flow; traditional methods follow sequential phases
• Kanban allows for changes throughout; traditional methods resist mid-project changes
• Kanban emphasises visualisation; traditional methods rely more on documentation.

Hybrid approaches (e.g., Scrumban)

Recognising the strengths of different methodologies, some teams adopt hybrid approaches. Scrumban, for example, combines elements of Scrum and Kanban:

• Uses Scrum’s sprint structure with Kanban’s visual board
• Maintains Scrum roles but adopts Kanban’s focus on flow
• Allows for more flexibility in planning and execution than pure Scrum.

By understanding these comparisons, teams can select or adapt methodologies to best suit their project requirements and organisational culture.
