# Project Management {attribution="[Principles behind the Agile Manifesto](https://agilemanifesto.org/principles.html)"} > Our highest priority is to satisfy the customer through early and > continuous delivery of valuable software. Agile project management methodologies, including [Kanban](wiki:Kanban_(development)), [Scrum](wiki:Scrum_(software_development)), and [SAFe](wiki:Scaled_Agile_Framework), facilitate the incremental delivery of complex products or services with indeterminate (or changing) requirements by shortening and interleaving enterprise performance life cycle phases. :::{figure} ../_static/project-management.svg :align: center The Project Life Cycle Cadenced agile ceremonies work like a reduction drive---represented here using belts---with annual contract awards or strategic plans propelling quarterly program increments (SAFe), semi-monthly sprints (scrum), and daily tasks (kanban). Agile projects end only when product development and service operation cease. ::: ```{toctree} :hidden: kanban charter backlog sprints ```
