During this period, agile practice emphasized lightweight, people-centric collaboration, rapid feedback loops, and minimal overhead to adapt to evolving requirements and market pressures. Extreme Programming emerged as a central method, prompting debates, case studies, and considerations of integration with traditional maturity frameworks and engineering rigor. Efforts also explored blending lightweight agile with plan-driven governance, alongside empirical assessments of effectiveness and dissemination through education. Influential Works: The Manifesto for Agile Software Development crystallized agile values and principles, prioritizing individuals, collaboration, working software, and responsiveness. Scrum for small teams introduced a lightweight framework with sprints, roles, and artifacts enabling empirical process control and faster feedback. Embracing Change with Extreme Programming highlighted customer involvement, continuous feedback, test-driven development, and frequent releases as foundations of modern agile engineering.
