A map of enterprise IT system classes: what each one does, who needs it, and what has to exist before it. The pyramid of IT systems, two implementation tracks and the order of work.

Five loops that serve employees rather than a business process: people, knowledge, IT support, data protection and the working environment. What each does and where AI fits.

Robots, app builders and language models: what each class does, who needs it, what has to exist first, and the mistakes that cost the most.
