The PPM data model is built around four core concepts — Projects, Work Items, Milestones, and Baselines — with work items connected to each other through parent–child hierarchy, links, and dependencies. Understanding how these relate is the key to understanding how Raytio's project tracking works.
PPM lets you plan, track, and deliver projects inside Raytio. You can create projects, break work down into epics, issues, tasks, bugs, and sub-tasks, organise them into milestones, and assign team members.
A Project is the top-level organisational unit in the PPM module. Work items can be grouped under a project, though this is optional — standalone and cross-project work items are also supported. Each project carries its own metadata, membership, and configuration.
