New to small fleet ops: how do you actually keep track of Day To Day tasks?

Hi there, I’m new to the maritime industry and trying to understand how things are handled in practice. I feel that full fleet management software would be an overkill for me.

For those working with small fleets, how do you usually keep track of: recurring tasks (maintenance, inspections, checks), who’s responsible for what, what is overdue,…?

Is this mostly done through: spreadsheets, paper logs, Outlook / calendar reminders, …?

One post on this enough.
