What do predictive, iterative, incremental, and Agile belong to?

A project life cycle is a framework of processes and phases used in delivering projects. It describes the high-level workflow of delivering a project and the steps you take to make things happen.
- Predictive project life cycles, such as Waterfall, follow a linear, sequential approach. Each phase of the project is completed before the next phase begins. This approach is often used for projects with well-defined requirements and a low risk of change.
- Iterative project life cycles, such as Agile, divide the project into smaller cycles, or sprints, and each sprint delivers a working product or feature that can be tested and evaluated by stakeholders. This feedback is then used to improve the product or feature in the next sprint. Agile is often used for projects where the requirements are likely to change or where there is a high degree of uncertainty.
- Incremental project life cycles deliver the project in stages, with each stage building on the previous one. This approach is often used for large, complex projects where it is difficult to define all of the requirements upfront.
