Software development has undergone a dramatic shift from the rigid, siloed Waterfall model to the agile, collaborative realm of DevSecOps. Although Waterfall offered predictability in a less connected world, its large teams and sequential phases became impractical in the fast-paced environment fostered by globalization and the internet boom of the 90s.
The demand for responsive, incremental, and iterative approaches gave rise to agile methodologies in the early 2000s, gaining momentum alongside disruptions like mobile, social media, and cloud computing. Agile replaced Waterfall’s rigidity with short, iterative cycles, focusing on rapid feedback and adapting to changing requirements. This shift empowered teams to deliver usable software sooner, refining it based on real-world user experience.
Today, the evolution continues with DevSecOps, blurring the boundaries among software development, security, and IT operations.
Innovations in how the teams are organized
With small, cross-functional teams as the cornerstone of agile, the quest for the right fit has sparked a wave of innovations. Innovations have so far focused on enhancing communication, collaboration, agility in adapting to changing business requirements, and continuous integration and delivery. These innovations have also extended beyond software development to encompass application maintenance, enhancements, and proactive embedding of security requirements.
