Effective software project management is crucial for the success of any project. However, with different methodologies available, it can be confusing to choose the right one for your project. Kanban, Lean and Six Sigma are three such popular software project management methodologies you can use today in your business.
This article aims to explain the differences between Kanban vs Lean vs Six Sigma, their advantages, disadvantages and how to choose the right methodology for your project. Check out our previous article on Waterfall Vs Agile Vs Scrum if you want to learn more about them instead.
Without any further ado, let’s dive right into it, starting with Kanban.
Kanban is a visual management system that helps teams manage and improve their workflow. It originated from the manufacturing industry but has since been adapted for software development. Kanban uses a board that visualises the work process and limits the amount of work in progress (WIP). Teams use cards or sticky notes to represent work items and move them across the board as they progress through the workflow.
The Kanban software project development methodology is based on a set of principles that guide how work is managed and delivered. Below are the six principles of Kanban.
Kanban’s reliance on visual management tools helps improve transparency, collaboration, and communication. Its flexibility allows teams to respond quickly to changing requirements and priorities. It seeks to identify and eliminate waste, reduce cycle time, and improve quality continuously. This helps improve efficiency and reduce costs. Additionally, its focus on customer needs and expectations allows you to deliver maximum value to your customers.
However, it can be seen as lacking in structure and planning. Its focus on the software development process means it can fail to address other aspects of software engineering, such as system architecture, user experience design, and testing. Its heavy reliance on individual expertise and knowledge can be a challenge when team members leave or are unavailable.
Also, it doesn’t provide a mechanism for prioritising tasks, potentially resulting in teams focusing on less important tasks and neglecting critical ones. Finally, since Kanban doesn’t limit the amount of work in progress, your team members may be overloaded and unable to complete tasks effectively.
Lean is a methodology that focuses on maximising customer value while minimising waste. It originated from the manufacturing industry but has since been adapted for software development. Lean aims to optimise the entire value stream, from ideation to delivery. It emphasises continuous improvement and the elimination of waste, such as unnecessary work, defects and delays.
Lean software project management is a methodology that aims to streamline the software development process, eliminate waste and maximise value to customers. The principles of this methodology include the following.
Lean software project management puts the customer’s needs and expectations at the centre of the development process, helping ensure that the end product delivers maximum value to the customer. It seeks to identify and eliminate waste, reduce cycle time, and improve quality continuously.
It allows teams to experiment, learn from failures, and continuously improve their processes, empowering them to learn and grow. Since it’s focused on delivering maximum value to the customer in the shortest possible time, time to market is also reduced.
However, it can be seen as lacking in structure and planning. This can make it difficult to manage complex projects and ensure that all aspects of the project are considered. There’s also a learning curve involved, which can take a while to get over for teams used to traditional project management methods. Additionally, the focus on delivering short-term results can sometimes result in a lack of attention to long-term goals and sustainability.
Another challenge is the prioritisation of working software over documentation, which can make it difficult to maintain and support the software over time. Finally, a potential con is that it doesn’t address other aspects of software engineering, such as system architecture, user experience design, and testing.
Six Sigma is a methodology that focuses on reducing defects and improving quality. It originated from the manufacturing industry but has since been adapted for software development. Six Sigma uses statistical analysis to measure and improve processes. It aims to achieve a defect rate of 3.4 defects per million opportunities (DPMO), which is equivalent to 99.99966% quality.
Six Sigma is a data-driven methodology that seeks to improve the quality of software products and services by reducing defects and variability in the software development process. The following are the main principles of Six Sigma software project management.
Six Sigma can help standardise processes and promote consistency across different projects. The reliance on data analysis to identify areas for improvement and make informed decisions is great because it can help reduce the likelihood of errors caused by human bias or subjective opinions.
Plus, by improving the quality of project outputs, Six Sigma helps increase customer satisfaction and build a reputation for delivering high-quality products or services. Finally, by reducing the occurrence of defects and errors, Six Sigma helps minimise rework and other costs associated with poor-quality outputs, leading to cost savings.
On the flip side, Six Sigma can be complex and require a significant amount of time and effort to implement effectively. Project managers may need to invest in training and resources to ensure that staff are familiar with the methodology and have access to the necessary tools and techniques.
Its heavy reliance on metrics and data analysis through solutions such as Pendo can sometimes lead to a focus on meeting numerical targets rather than addressing underlying issues or meeting customer needs. Also, Six Sigma may not be suitable for all types of software projects, particularly those that involve significant creativity or innovation.
Kanban, Lean, and Six Sigma are all effective methodologies for software project management. Choosing the best one for your business depends on several factors, such as the nature of the project, the team’s skills and expertise, the business’s goals, and the resources available. It all comes down to what you want and which suits your specific business needs and situation.
Kanban is a good choice for projects that require a flexible approach, such as those involving continuous delivery and improvement. It is also ideal for projects that require a visual management approach, where teams can easily track progress and communicate information across teams. Kanban is a popular choice for Agile software development teams, and it promotes a culture of collaboration and continuous improvement.
Kanban software project management methodology can be useful for:
Lean is an ideal choice for projects that require a customer-centric approach and focus on delivering value. It is suitable for projects that involve complex processes and require continuous improvement. It is a data-driven approach that relies on metrics to identify inefficiencies and improve processes.
The Lean methodology can be useful for:
Six Sigma is great for projects that require a data-driven approach and focus on improving quality. It relies on data and statistical analysis to identify inefficiencies and improve processes. Six Sigma is suitable for projects that involve critical systems and processes and require a high degree of accuracy and precision.

Ultimately, the best software project management methodology for you depends on your specific project requirements and your team’s skills and experience. It’s essential to evaluate the strengths and weaknesses of each and choose the one that best aligns with your project goals and objectives. Plus, ensure you remain open to feedback and continuously evaluate the project’s progress and adjust the methodology as needed.
Yes, you can combine Kanban, Lean, and Six Sigma in your software project management approach, as well as mix and match as needed. Each methodology offers different benefits and can be applied to different aspects of the project management process.
For example, Kanban can be used to visualise the workflow and track progress in real-time, while Lean can be used to identify and eliminate waste in the process. Six Sigma can be used to ensure that the project meets the required quality standards and that any defects or errors are eliminated.
By combining them, businesses can create a customised project management approach that meets their specific needs and goals. It’s important to note that implementing multiple methodologies can be challenging and requires careful planning and coordination. The key is to identify the strengths of each and how they can be used to complement each other.
In conclusion, Kanban, Lean, and Six Sigma are all popular methodologies for software project management, each with its own unique strengths and weaknesses.
