This. I spent plenty of time making sure there is enough documentation and attempting to get feedback on it, the project roadmap, milestones/schedule etc with a team that had almost zero engagement. Once I left, they weren't able to put things together despite a clear todo list of rewiring services to finish the project. it doesn't matter what architecture, amount of documentation, testing, how clean the code is etc, if your team is not engaged and doesn't share the same vision of where the project should go, the project is doomed to fail once you leave.
