There are two types of UX design — customer UX and enterprise UX. The former is used in apps for the general public, the latter in workplace apps used by employees in different roles in different industries.
Customer UX usually influences interaction with the app and brand loyalty, but enterprise UX is concerned with employees' overall productivity. Some outcomes of bad enterprise UX are costly errors, wasted time, decreased productivity, and employee dissatisfaction.
Mistakes. A RetEx app is a merchandiser's key instrument, which lets them do their job more effectively. But if the design isn't intuitive and responsive one can choose the wrong function or skip a task, which influences both the outcome and the store or retail chain's performance.
Waste of time. A slow app that takes ages to load and open new screens takes up precious time, so merchandisers spend more time on routine tasks that automation was supposed to make faster and easier.
Decreased productivity. Many workplace-app processes are time-consuming, confusing, or unnecessary. This leads to employees becoming distracted, discouraged, and less likely to meet their goals.
Unsatisfied employees. If your work is hard, not because you're unskilled but because your app isn't accurate or suitable, you tend to be unsatisfied with your job. And this dissatisfaction can go two ways: either the app is changed because of bad feedback or you change jobs.
