Agile development, characterized by its iterative and incremental approach, is widely adopted by software teams, but the question of what will follow agile remains. Agile methodologies, such as Scrum, are rooted in historical iterative processes like the Shewhart and Deming Cycles, which emphasize planning, executing, studying, and acting to foster continual improvement. The Deming Cycle, in particular, has been a cornerstone in quality improvement for nearly a century and influences modern practices like Lean and Jobs to be Done. Despite the potential for new methodologies to emerge after agile, the enduring utility and philosophical depth of the Deming Cycle suggest it will continue to play a fundamental role in future development paradigms. As teams strive to enhance both their processes and products, a deeper understanding of the Deming Cycle could facilitate this advancement.
