Hi Roopesh1986,
According to your description, it is an existing MVC application with database, to add approval process functionality, you may need to modify/add new tables to store data bout approval requests and process details, and as bruce
mentioned, you may need to maintain approval request-Manager-GM to control approval chain.
For functionality of sending/pushing notifications to the users, you can achieve it by sending email or using [SignalR](https://docs.microsoft.com/en-us/aspnet/signalr/overview/getting-started/tutorial-getting-started-with-signalr-and-mvc)
in your web application.
Note: please backup your database and web application first before you do modifications or updates on it.
With Regards,
Fei Han
