What Does The Path From Ad Hoc To Elite Actually Look Like?
Improvement programmes fail when they attack everything at once. Capability builds in an order — you cannot do meaningful continuous delivery before you have tests you trust — and doing it out of order wastes the quarter.
Teams copy the practices of organizations several stages ahead and adopt the artefacts without the prerequisites. The practice fails, and the conclusion drawn is that it does not work here.
Questions CTOs ask
- 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.
