Difference between Lean Development Model and Agile Development Model

In this article, we will understand the difference between the lean development model and the agile development model, but before that, we are going to comprehend the meaning of the lean development model and the agile development model.

Lean Development Model

The lean development model is a software development method that focuses on lean manufacturing principles and the Toyota Production System. The primary goal of this method is to remove waste and increase the efficiency of the product by continuously providing small & high-quality increments of the software.

The concept of Lean focuses on constantly improving a company's process and making products as efficient as possible. It delivers the product to the customer, takes feedback from the customers, and improves the efficiency of the product. It encourages a culture of collaboration, transparency, and experimentation. It allows the team to adapt to changing needs and market conditions.

Principles of lean development model:

• It focuses on eliminating waste such as redundant work, unwanted features, errors, etc. It primarily removes any activity that does not benefit the finished product.
• It works on the basis of insights gained from customer feedback.
• It promotes continuous learning and improvement throughout the entire process of development. It empowers the team to collaborate, innovate and constantly improve their work.
• It provides working software in small, incremental releases, permitting faster feedback loops and the capability to respond to changing customer needs.
• It optimizes the entire system instead of optimizing individual parts alone.
• It focuses on the importance of building quality into the development process from the start using practices such as automated testing, continuous integration, and continuous deployment to make sure high quality throughout the development lifecycle.
• It promotes creating and sharing knowledge within the team and the organization.
• It respects the people working on the project and provides the resources they require to create a valuable and effective project successfully.

Agile Development Model

The agile development model is a software development method focusing on collaboration, flexibility, and iterative delivery. It values customer satisfaction through the quick and continued delivery of valuable software and strives to adjust to varying conditions during the development process.g

The agile model implicates breaking down the development process into smaller iterations called sprints, with each sprint providing a functional enhancement of the software. It encourages teamwork and frequent communication, which improves software quality and quick delivery times.

Principles of agile development model:

• It focuses on people working together on the project and communicating effectively.
• It focuses on delivering small, useful increments over weeks rather than months or years, often to get initial feedback and iterate based on it.
• It encourages close collaboration with customers, users, and other stakeholders to get their feedback and work on the project accordingly.
• It focuses on face-to-face communication as it is more effective than written communication.
• It measures progress primarily through working software,
• It focuses on the importance of technical excellence and good design to ensure that software is scalable, maintainable, and of high quality.
• It recognizes that requirements and solutions may change during the development process and encourages teams to adjust and adapt modifications.

The main differences between Lean development model and Agile development model

Conclusion:

In this article, you have discovered the difference between lean development model and agile development model. We have concluded that the lean development model is a software development methodology primarily focusing on reducing waste and optimizing efficiency throughout the development process. In contrast, the agile development model is a software development methodology primarily focusing on flexibility, adaptability, and customer feedback. Both models have their strengths and can be effective, depending on the software development project's particular needs and preferences.
