#1 Learn about it
What I recommend to leaders is; find out what others experience when they use your app. How do they use it? Is it different than you thought they would? Chances are, your users use your app in varying ways and for slightly different purposes than you may have thought they would.
By watching and listened to just a few users talk about this prototype, we learned that people interpreted the 6 HRS in a couple different ways (2 out of 3 were not intentional to the designers):
- 6 HRS could be the hours left until their time sheet is due. We learned that some users wanted a feature like this to help provide a countdown for them. This was not a feature we had previously thought of. k
- 6 HRS assumes that a worker has an 8 hour work day. A couple folks mentioned they work a 6 hour day or a 10 hour day.
- 6 HRS originally intended to inform the user that 6 out of 8 of their work day hours were allocated to a capitalizable (or billable) project. We thought this was important but we did not verify this aspect with users prior to the prototype.
#2 Make small improvements consistently over time
You've done a lot of work to get where you are. Don't go redesigning the whole thing (at least not until you do #1 above).
By learning about your app from users, you can identify specific ways to improve aspects of your site that will help your users continue to feel you are on the ball. By making small changes, users will still feel at home with your app and not feel disoriented by the changes. They will hopefully be grateful that little snafus they've put up with with your app are getting smoothed out.
#3 Remove Complexity
Sorry but, that usually ends up in too many features implemented in a way that the original vision gets muddied up with loose ends and not-well thought out implementations.
Instead, identify your "special sauce". What have you done really well in your app? Chances are, you (or someone else) have really thought through those experiences and paid attention to the micro-interactions.
If possible, you may want to simplify some of the features you rolled out prematurely until you have a chance to implement them in a way that feels complete and smooth.
