The document describes how Lean and Agile project management techniques like Scrum and Kanban can be combined with a process engine. It provides an example story of a project going through the process. The story shows a project lead creating a new project and team. A product owner then adds tasks to the backlog. A team member discusses and completes tasks, moving them between backlog, todo list, in progress, and done states. The process engine allows tracking of roles, tasks, and conversations throughout the project lifecycle for accountability.
