About Lean

Origin of Lean: Lean principles stem from the manufacturing industry, specifically from the Toyota Production System (TPS) developed by Toyota in the 1950s. Toyota aimed to optimize production processes by minimizing waste, increasing efficiency, and improving overall value. The essence of lean is to deliver maximum value to customers while minimizing resources, time and effort.

In the context of software development and IT, lean principles have been adapted and applied to improve processes, reduce inefficiencies and deliver better results. Lean software development focuses on delivering high-quality software products through a set of principles that emphasize customer value, continuous improvement and waste reduction. In concrete terms, this can mean understanding customer needs and focusing development efforts on features and functionalities that directly contribute to customer satisfaction.

Lean identifies various forms of waste, such as overproduction, waiting times, unnecessary processes, defects, etc. In software development, waste can manifest itself as unnecessary features, excessive documentation, and inefficient workflows. By eliminating such waste, teams can streamline development and increase productivity.

Lean promotes the concept of continuous improvement, where teams regularly evaluate processes and practices to identify areas for improvement. In software development, this means iterative development, frequent feedback, and adapting to changing requirements to create better software products over time.

Lean encourages empowered and cross-functional teams. It involves individuals with different skills (developers, testers, designers) working together to deliver complete and high-quality features.

Lean emphasizes a pull-based system, where work is initiated based on actual demand. In practice, this means developing features when they are really needed, reducing unnecessary work and potential rework.

Lean encourages the delivery of smaller, incremental improvements rather than large, complex solutions all at once. This approach leads to faster releases, faster feedback loops and easier adaptation to changing requirements.

Lean places great emphasis on respecting people's skills, input and well-being, fostering a culture of collaboration, open communication and continuous learning.
