Why it exists
Joshua tried hard at jobs where the process lived in someone else's head. He still forgot steps. When something went wrong, there was little proof of what he had been asked to do — or that he had done it. Managers got frustrated. He got frustrated. The jobs did not last.
EVIRAIL exists so that conversation has a fair record. Crews get a clear path to follow while the work is happening. Managers get proof of what happened afterward — not a debate about who remembers what.
