I had done an assignment for an MEP consultancy firm where I was asked to design the below mentioned feature for the mobile app:
A user will create an issue in the app and tag 2 people (Person 1 and Person 2), both will be notified:
Person 1 will be the maker who will work on the issue at the construction site and mark the issue as completed for approval by checker.
Person 2 will be the checker who will check if the issue has been completed or not.
Both can upload images as well.
If Person 2 approves, the issue will be closed.
If Person 2 disapproves, the issue issue will again go to the maker for rework.
I had designed the mobile app screens for the above process in Figma.
