"I think it depends on if the person originally doing the task is still available for training or not. If they are, I would prefer to have the chance to sit with them and learn in person, watching their process and taking notes. If they are already gone, either they've left the company or are out on sick leave, I would rely on any written or video training available and look through any old records from previous iterations of the task to see what steps the original person took. I'm always on the lookout for ways to update or enhance processes when possible. I understand sometimes that is not an option, but I like to find ways to add efficiencies."
