Principles

How we keep the work credible in regulated and contractor-led environments.

Structure over free-text

Consistent records, repeatable outputs, and fewer "interpretation" gaps during audit and handover.

Operational-first UI

Designed for technicians on site, not slide decks; fast access, clear fields, and controlled editing.

Auditability by design

Evidence that can be reviewed, exported and relied upon, without turning the platform into "task management".
