Frequently Asked Questions
What is a technology tree?
A technology tree (tech tree) is a visual progression map inspired by strategy games like Age of Empires. It shows capabilities organised by domain (columns) and maturity level (rows), with dependency lines showing what must be achieved before advancing. Each node includes effort estimates, actionable steps, and links to relevant tools.
How do I use the tech tree for my organisation?
Select an organisational tree (like Engineering Org Maturity or Security & Compliance), then mark nodes as completed based on your current state. The tree automatically highlights what is available to work on next based on prerequisites. Click any available node to see the concrete steps required to achieve it.
