The Complex Data Process is a strategy that is implemented through test automation technologies. Programmatic code functions help implement the process of breaking down and analyzing the data into small, manageable tasks. This creates opportunities to refine and improve it over time. Gains are also realized in reusability, leading to a greater return on investment (ROI).
