Is it possible to see tasks assigned to other assignees in the setting? It says it can be set up in My Nintex but I think it only applies to the tasks that I am assigned.
Here is another idea, but it takes a little more work than making everyone a business owner. You could create a dashboard for the users. In NWC you can define connectors to other applications and data stores. You could use one of these connectors to write data in your workflow, then use a tool for that other application to display the list of active workflow requests. You could even update that data as the workflow progresses with the current status of the request.
If you have a SharePoint connection, you could create a SP List with columns that convey information about the request. The list will act like a dashboard allowing the users to see what is happening at a glance. Keep in mind, SharePoint has some recommended limits for the number of items in a list and if you exceed those limits you may get throttled or experience performance degradation. If you think you will approach the recommended limits of SharePoint, consider storing your data in a database like Azure SQL.
I haven't really started yet, but we are very keen to have dashboard/reporting feature build up for the firm hence very likely to go for that route. Can I have another question please? Is it possible to view the filled forms following the initial forms as a business owner? It seems not so from what I can see. Thanks!
