I don’t have experience in data management process but I’ve seen how other people do.
Data backup and recovery plan- This step is the step that they care most because they are worried about they will lost data. They save in laptops and USB drive.
Edit check and logical check- I ask them how to do it and they admitted that they can’t check all the details and they just check some obvious errors and mostly they do skimming.
User authentication and access control level- they use excel sheet and share between the groups but not strict authentication. If someone enter the link, all the data can be seen and can be edited or can be edited.
Audit trial/ time stamp- They use time stamps in excel sheets and can be seen who edit, delete or enter the data.
