Description: The practice of making a process more efficient by eliminating waste and improving flow is fundamental in software development, as it seeks to optimize the performance and quality of application development. This approach is based on identifying and removing elements that do not add value to the process, such as redundancies, inefficiencies, and bottlenecks. By improving flow, collaboration between teams is facilitated, delivery time is accelerated, and customer satisfaction is increased. Efficiency in software processes not only translates into a more effective use of resources but also allows for greater adaptability to changes and better risk management. In this context, various methodologies and tools are used, such as Lean, Agile, and DevOps, which promote continuous improvement and the integration of practices that foster quality and speed in development. The elimination of waste can encompass everything from simplifying software processes to automating testing and deployments, resulting in a more agile and efficient software lifecycle. In summary, this practice is essential for building robust and scalable systems that respond to the changing needs of the market and users.
