Lean vs Kanban: Understanding the Key Differences in These Agile Methodologies

Agile as a methodology has other frameworks and methodologies that are subsets to it. Think about them as various flavors of the methodology.

While methodologies all adhere to the Agile Manifesto, they each have their different nuances and method of application.

Lean and Kanban are two popular methodologies under the Agile approach umbrella that are used in the field of project management and software development.

While both of these methodologies aim to optimize processes and increase efficiency, they differ in their focus and application.

In this blog post, we will explore the key differences between Lean and Kanban, their advantages and disadvantages, and when each methodology is best suited for your project and team.

Introduction to Lean Methodology

Lean is a methodology that originated in Japan by Toyota in the 20th century. The methodology was originally used in the manufacturing industry but was later adapted for use in other fields over time.

The goal of Lean is to create a smooth and efficient process that delivers value to customers as quickly and effectively as possible.

This is achieved by identifying and eliminating waste and continuously improving the process based on feedback and data.

One of the key principles of Lean is the idea of “flow.” This means creating a process that allows work to flow smoothly and continuously, without bottlenecks or interruptions.

Teams using Lean aim to create a process that is “pull-based” rather than “push-based,” meaning that work is started only when there is a demand for it.

Another important aspect of Lean is visual management. Teams using this methodology use visual aids, such as boards or kanban systems, to see the flow of work and identify areas for improvement.

By using visual management, teams are able to see the big picture and make data-driven decisions to optimize their process.

Introduction to Kanban Methodology

Kanban is a visual system that is used for managing and optimizing work processes.

It originated in the manufacturing industry in Japan and has since been adopted by organizations across various industries for software development, marketing, HR, and more.

One distinguishing feature of this methodology that sets it apart from others is its focus on continuous delivery and improvement.

Rather than following a set timeline or rigid process, Kanban allows teams to adjust and improve their workflow as they go.

In a Kanban system, tasks are represented by cards on a board, and the board itself is used to visualize the flow of work.

The board is divided into columns that represent different stages of a task, such as “to do,” “in progress,” and “done.”

As tasks move from left to right, the team is able to see what’s been completed and what still needs to be done.

One of the key principles of Kanban is limiting work in progress. This means that teams only start on a new task once they’ve finished the one they’re currently working on.

By limiting the number of tasks being worked on at once, teams can reduce the risk of overload and ensure that each task is given the attention it needs.
