What should I check before accepting the design delivery?

That’s the question you should ask yourself when you see the delivery from the hired design agency. As a mobile development agency, we see many mockups that clients come to us with. And the design qualities are always different, but there are common mistakes. Some of them are obvious. For example, whether you like how it looks, do you like colors, or is the designer’s reasoning clear to you. However, some issues are only seen by professionals.

I’ll tell you about different criteria with different subjectivity levels, but some are quite objective. It would help if the designer did not forget about the following:

1. Empty states
2. Loading states
3. Error states
4. Official guidelines conformance
5. References

Make your app look filled even when there is no content.

If your app operates with data, there may be cases when you don’t have any data stored. E.g., if you want to develop a Notes app, your user may start fresh without any notes or delete all of them later. In this case, you’d probably want to see a clarification on the screen displaying the list of all user’s notes. Something like: “You don’t have any notes yet. Just get down to business.”, maybe in a less intimidating way and with a nice picture associated with emptiness or eagerness to start the creative process. You should see that version of the screen in the design mockups; it’s not something implied.

Entertain the user while content is loading

If your app works with a backend, it will need time to load the data, and the user doesn’t want to stare at an empty screen. It may be the place to show your customers some tips or entertain them somehow. Maybe you don’t know how to do that, then ask for some beautiful animation, so the user’s eye is not bored. That may be important because the user may leave just because the app without any animation or content looks like it’s not working. Users delete apps that are not working.
