Two of the most popular and widely used methodologies are Kanban and Agile. Both have their own strengths and weaknesses, and teams are often left wondering which one is better suited for their needs. In this article, we’ll delve into the world of Kanban and Agile, exploring their histories, core principles, and application in real-world scenarios. By the end of this article, you’ll have a clear understanding of which methodology is better for your team.
A Brief History of Kanban and Agile
Before we dive into the nitty-gritty of Kanban and Agile, let’s take a brief look at their origins.
The birth of Kanban
Kanban, a Japanese term meaning “visual board,” was first introduced in the 1940s by Toyota’s chief engineer, Taiichi Ohno. Ohno was tasked with improving the efficiency of Toyota’s production line and reducing waste. He created a system that relied on visual cues to manage the flow of production. This system, known as the “Toyota Production System,” was designed to be flexible and adaptable, with a focus on continuous improvement.
The Agile Revolution
In the early 2000s, a group of software developers gathered at a ski resort in Utah to discuss the challenges they faced in their industry. This meeting, known as the Agile Manifesto, marked the beginning of the Agile movement. Agile was designed to be a more flexible and iterative approach to software development, focusing on collaboration, customer satisfaction, and rapid delivery.
Core Principles of Kanban and Agile
Now that we’ve covered the history of both methodologies, let’s dive into their core principles.
Kanban Core Principles
Kanban is built around five core principles:
- Visualize the workflow: Kanban relies on a visual representation of the workflow to manage and track progress.
- Limit Work in Progress (WIP): Kanban emphasizes the importance of limiting the amount of work in progress to reduce waste and improve efficiency.
- Focus on flow: Kanban teams focus on the smooth flow of work, rather than individual tasks or projects.
- Continuous improvement: Kanban encourages continuous improvement through regular retrospectives and feedback loops.
- Pull-based workflow: Kanban teams work on a pull-based system, where work is pulled into the system as capacity allows.
Agile Core Principles
Agile is built around four core values and 12 principles:
- Individuals and Interactions: Agile prioritizes individuals and interactions over processes and tools.
- Working Software: Agile emphasizes the importance of working software over comprehensive documentation.
- Customer Collaboration: Agile involves customers throughout the development process to ensure their needs are met.
- Responding to Change: Agile teams are designed to respond quickly to change and adapt to new requirements.
The 12 Agile principles include:
- Our highest priority is to satisfy the customer.
- Welcome changing requirements.
- Deliver working software frequently.
- Close, daily cooperation between business people and developers.
- Projects are built around motivated individuals.
- Face-to-face conversation is the most efficient and effective method of communication.
- Working software is the primary measure of progress.
- Agile processes promote sustainable development.
- Continuous attention to technical excellence and good design.
- Simplicity – the art of maximizing the amount of work not done.
- The best architectures, requirements, and designs emerge from self-organizing teams.
- Regularly, the team reflects on how to become more agile and adjusts its behavior accordingly.
Key Differences between Kanban and Agile
While both Kanban and Agile are iterative and incremental approaches to project management, there are some key differences between the two.
Structure and Planning
Agile uses a structured approach to planning, with sprints, iterations, and milestones. Kanban, on the other hand, is more flexible and adaptable, with no set iterations or sprints. Agile teams typically plan and prioritize their work at the beginning of each sprint, while Kanban teams focus on the flow of work and adjust priorities as needed.
Roles and Responsibilities
Agile teams typically have defined roles, such as product owners, Scrum masters, and team members. Kanban teams, on the other hand, do not have defined roles, and responsibilities are often shared among team members.
Metrics and Goals
Agile teams often focus on velocity, burndown charts, and sprint goals. Kanban teams, on the other hand, focus on lead time, cycle time, and throughput. Agile teams also often have a clear definition of done, while Kanban teams may not.
Scalability
Agile is often more difficult to scale than Kanban, as it relies on cross-functional teams and can become cumbersome with large teams. Kanban, on the other hand, is more scalable, as it can be applied to teams of any size.

What is Kanban, and how does it differ from traditional project management methods?
Kanban is a visual system for managing work, emphasizing continuous flow and limiting work in progress. It originated in the manufacturing industry but has since been widely adopted in software development, IT, and other knowledge work domains. Kanban differs from traditional project management methods in that it doesn’t rely on predefined sprints or phases, instead focusing on continuous delivery and improvement.
In Kanban, teams work on a continuous flow of tasks, and the workflow is divided into columns representing different stages of work. The team then pulls work from the leftmost column, moving tasks through the workflow as they are completed. This visual approach helps teams identify bottlenecks, optimize processes, and respond quickly to changing priorities.
What is Agile, and how does it differ from Scrum?
Agile is an iterative and incremental approach to project management, emphasizing flexibility, customer satisfaction, and team collaboration. Agile is a broad framework, and Scrum is one of the many methodologies that fall under the Agile umbrella. Agile focuses on delivering working software in short iterations, called sprints, with continuous improvement and refinement.
Agile differs from Scrum in that Agile is a more general framework, providing a set of values and principles for guiding project management. Scrum, on the other hand, is a specific methodology that implements Agile principles. Scrum provides a more structured approach, with defined roles, ceremonies, and artifacts. While Agile is a mindset, Scrum is a particular way of implementing Agile.
How does Kanban handle prioritization, and is it as effective as Agile’s prioritization methods?
Kanban doesn’t provide a built-in prioritization method, unlike Agile, which emphasizes prioritization through prioritized backlogs and iterative planning. However, Kanban teams can adopt various prioritization techniques, such as using ranking, categorization, or cost-benefit analysis. Prioritization in Kanban often occurs through collaboration and discussion among team members, product owners, and stakeholders.
While Kanban’s lack of built-in prioritization might seem like a weakness, it also provides an opportunity for teams to adapt and evolve their prioritization approach as needed. Kanban teams can experiment with different methods and find what works best for them. In reality, both Kanban and Agile can be effective for prioritization, as long as the team is committed to continuous improvement and collaboration.
Can Kanban be used in combination with Agile, or are they mutually exclusive?
Kanban and Agile are not mutually exclusive, and many teams successfully combine elements of both approaches. Hybrid approaches, such as Agile-Kanban or Scrumban, integrate the strengths of both methodologies. These hybrids might use Agile’s iterative approach and Scrum’s ceremonies, while incorporating Kanban’s visual workflow and continuous flow principles.
Combining Kanban and Agile can help teams leverage the benefits of both methodologies, such as Kanban’s flexibility and Agile’s structured approach. By choosing the best elements of each framework, teams can create a customized approach that suits their unique needs and workflows.
Which methodology is better suited for teams with varying skill levels, Kanban or Agile?
Kanban is often better suited for teams with varying skill levels, as it focuses on visualizing the workflow and limiting work in progress. This approach helps team members understand the workflow and their role within it, regardless of their skills or experience. Kanban’s emphasis on continuous flow and immediate feedback also helps teams identify knowledge gaps and skill deficits, allowing for targeted training and development.
Agile, on the other hand, requires a higher level of collaboration, self-organization, and communication among team members. While Agile can be effective with diverse teams, it demands a certain level of maturity and expertise. Kanban’s more flexible and adaptive nature makes it a better fit for teams with varying skill levels, allowing them to grow and develop their skills over time.
How does Kanban handle change management and adapting to new requirements?
Kanban is well-suited for handling change management and adapting to new requirements, as it emphasizes flexibility and continuous flow. The visual workflow provides immediate feedback on changes and their impact on the team’s workload. Kanban teams can quickly respond to changing priorities by re-prioritizing tasks, adjusting WIP limits, or adding new columns to the board.
Kanban’s adaptive nature also encourages teams to reflect on their processes and make adjustments as needed. This mindset helps teams develop a culture of continuous improvement, where change is seen as an opportunity for growth and learning. By embracing change and uncertainty, Kanban teams can respond more effectively to new requirements and shifting priorities.
What are the key performance metrics for measuring the success of a Kanban or Agile team?
Key performance metrics for Kanban teams include lead time, cycle time, throughput, and flow efficiency. These metrics help teams understand the speed and efficiency of their workflow, identify bottlenecks, and make data-driven decisions. Additionally, Kanban teams might track metrics such as WIP, queue size, and blockers to gain a deeper understanding of their workflow.
Agile teams often focus on metrics such as sprint velocity, burn-down rate, and iteration success rate. These metrics provide insights into the team’s ability to deliver working software within the sprint, and help identify areas for improvement. Both Kanban and Agile teams should choose metrics that align with their goals and objectives, and use data to drive continuous improvement and refinement.
