Now that your CRM note data is in Zoho analytics, have fun working with it! There are a variety of reports and metrics that you can build. Here are a few ideas:
Note counts by salesperson
Time lag between record creation and the first note created for that record
Note counts by weekday, month, or even hourly (when are your salespeople more actively leaving notes on records?)
Which records don’t have notes (and might need follow-up)?
Are all notes created and left alone or are any edited later?
