This document discusses different approaches to process organization using Kanban and Scrum. It describes how the Just In Time approach using a Kanban system can be effective at different stages of the product life cycle from research and development to post-launch support. At each stage, it outlines the appropriate context, roles, and approaches including using multiple synchronized Kanban boards and adjusting practices like planning and retrospectives based on needs. The key takeaway is that Kanban and Scrum can be combined effectively depending on circumstances rather than viewing them as separate options.
