Vantaggi
Project managers know what they're doing and champion work. Working on an internal knowledgebase.
Svantaggi
Shareholders and upper management have no concept of providing consistent expectations. Codebase is a mess with no prioritization of tackling tech debt. New versions of products don't address any code smells, anti patterns, known issues, or tech debt - just slap a few extra features on it and charge customers for the upgrade. Also waaaaay too enthusiastic about slapping AI on everything with no clear direction.
