Vref+5, doesn’t sound good. When TSHTF in an organisation, the scene is as you described. People leave and aren’t replaced, the rest are head down, trying not to get noticed. They know there is big trouble coming, well before senior management does.
The information I thought I saw - about CASA doing some IT based “transformation”, if true, is a desperate attempt to stave off organisational disaster. An IT solution to perceived problems is often proposed by managers trying to buy time and fix serious issues and it always fails.
The reason it fails is that if a business process is paper driven but “broken” then trying to computerise it just makes it worse. If CASA regulations are unclear now, just wait until a software architect tries to turn them into machine logic.
