Sorry if this was already said; MyDay is not built with the actual end user in mind.
Example:
It takes 3 steps after opening MyDayto get into the backstock process.
1. Go-to Home.
2. Click on Fill and Backstock from Task list.
3. Click on Backstock. This opens the backstock application with in MyDay.
3a. Scan item.
3b. Scan location.
3c. Enter Quantity.
Repeat as necessary.
Seems straight forward; but it doesn't list fillgroup (since that's apparently not a thing) okay. It also doesn't show any additional information that would help like salesfloor location (we have a few backroom valleys set up by salesfloor aisle, similar to custom blocks). So located similar items together can happen.
You can't switch to Scan without closing backstock and then repeating the 3 steps to get back into backstock. You can't backstock from Scan either or I haven't seen a way to do so.
The user interface should be built with two things in mind:
1. Don't make me think. If it's not intuitively layed out, it's going to be a frustrating mess and people will not use it properly, or at all.
2. If I have to press more than 1 button to complete a process, I've already pressed too many.
Asking me if I'm sure. Or if I want to cancel. Or making me drill down into an application more than one level for information that should be top-level. Is bad user design. If you have to bury important functions in sub-menus. You aren't thinking of the user. You're just adding unnecessary stuff and fluff.
