I am using Nintex workflow to create approval workflows for the multiple forms on SharePoint. Nintex is connect to the SharePoint and Outlook. We have forms which need multiple levels of approval in them. This is very time-consuming to set up. The challenge was to notify the approver, register the approval, inform the requester of the result and finally document the approval for the future reference. Through Nintex, it’s very simple, fast and very systematized. The process is simple to follow. The notification comes directly to your Outlook inbox after approval rejected / approved the answer will come directly to the requesters inbox. This is very simple and effective and the amount of time saved in this process was really remarkable.
