Explanation

Crystal Clear is a lightweight Agile methodology developed by Alistair Cockburn, designed for small co-located teams. It defines 'project safety' through properties that include efficiency (team members can be productive without excessive overhead) and habitability (the process is comfortable enough to sustain). Crystal Clear's seven properties include Frequent Delivery, Reflective Improvement, Osmotic Communication, Personal Safety, Focus, Easy Access to Expert Users, and a Technical Environment with Automated Tests. Scrum, Kanban, and XP do not use these specific 'project safety' properties.
