Sacsayhuaman, a fortress-temple complex built in the 15th century near Cuzco, exemplifies the Inca's architectural brilliance with its precisely interlocked stone structures, illustrating the importance of trial and error in innovation. This historical context parallels modern product development, where perfection is often pursued at the expense of incremental progress. Emphasizing the value of experimentation, the article draws parallels with companies like Netflix and Airbnb, which use iterative testing and data-driven decision-making to enhance user experiences. By embracing small, continuous improvements and learning from each experiment, these companies demonstrate that incremental progress can lead to significant innovations. The article advocates for product teams to adopt a similar experimental approach, emphasizing the importance of creativity, rigorous testing, and adaptability in achieving high-quality outcomes.
