Agile Manifesto is a set of guiding principles that revolutionized the world of software development and product management. It emphasizes collaboration, adaptability, and iterative development. Instead of following strict plans and processes, Agile Manifesto encourages teams to be flexible and responsive to change. It values individuals and interactions over processes and tools, working software over comprehensive documentation, customer collaboration over contract negotiation, and responding to change over following a plan. Adopting Agile Manifesto helps product managers and software teams to deliver high-quality products that meet customer needs efficiently.
