Which framework is used to manage complex software development projects through iterative and incremental practices?

The framework that is most commonly used to manage complex software development projects through iterative and incremental practices is Scrum. Scrum is designed to facilitate teams in adapting to changing requirements while ensuring ongoing delivery of high-quality software.

This framework promotes regular reflection and adaptation, breaking the project into manageable units called sprints, typically lasting 2-4 weeks. Each sprint aims to produce a potentially shippable product increment, allowing teams to assess progress frequently and make adjustments as necessary based on stakeholder feedback or changing priorities.

In contrast, Waterfall is a linear project management approach where the project flows sequentially through distinct phases, making it less adaptable to changes once a phase is completed. Lean focuses on maximizing value by minimizing waste, while Kansei is a concept linked more to emotional design in product development than to software project management. These differences highlight why Scrum is the preferred framework for managing complex projects in a dynamic software development environment.
