The Fall of Agile: A Retrospective on Software Development

Agile, once hailed as a revolutionary approach to software development, has been criticized for its lack of clarity and practical application. Despite its widespread adoption, the Agile Manifesto offers little more than vague principles, leaving many to question its true value. The manifesto's emphasis on customer collaboration and adaptability often clashes with the realities of commercial software development. Agile's identity has been largely defined by what it opposes—namely, the Waterfall model, which was already recognized as flawed by the 1970s. Historical figures like Winston W. Royce had already proposed iterative development practices that Agile later claimed as its own innovations.

The article argues that the true innovations in software development predate Agile, with iterative and spec-driven development practices already in place. The rise of large language models (LLMs) has further shifted the focus back to comprehensive documentation, challenging Agile's dismissal of it. By emphasizing the importance of clear specifications, LLMs have inadvertently revived older, more structured development methodologies.

As the software industry evolves, it's time to reassess Agile's contributions and consider moving beyond it. The article suggests that Agile's vague promises have been overshadowed by more concrete and effective development strategies that were established long before Agile's inception.
