Sandeep;

Since you mean a welcome screen upon login, as you're indicating it 
includes the username, it's a system response to let the user know they 
have successfully logged in.  If a user successfully completes a task in 
any given system and there is no system response indicating so, it's not 
much better than poor or no system responses when a task has not 
successfully been completed.

Assuming the application in question has an authenticated and 
non-authenticated state, something indicating which state the user is in 
becomes important.  Now, this can also be accomplished via something like 
a small text welcome message with the username in an unobtrusive upper 
corner on the UI, and making this link to profile or personal settings.

I don't know if this particular case needs specific research to support 
it, as system responses are a pretty standard usability issue.

Welcome message with user name on web application
Sent by:

Hello,

Why do we need to show welcome message on the application UI?

This was the question I faced today while discussing the product user 
interface with my product manager, which made me realize that I did not 
have a very good answer for it, as I have never tried to find out why and 
kept using it on all my designs as it was seen on other applications too. 
Can someone point to some research or guidelines on why to use the welcome 

message with user name for web based applications?

Thanks
Sandeep Rathod
