Successful UX design is often about deploying new solutions to solve problems. You need to know what the problem is to design a solution to solve it.
The key to problem analysis:
- Define the problem
- Gather evidence
- Predict impacts
- Identify causes
- Make recommendations
When the causes of problems are properly stated, your recommended solutions are simply the reverse of the causes.
One major challenge is to find the root cause of the problem and not focus on the symptoms of a problem.
For example, if pictures on a website are loading very slowly, a solution could be removing the pictures, but it doesn’t solve the problem. The root cause could be the file size loaded on the website or the type of server. Your task will be to identify the root cause and then suggest a solution that will prevent any image to load slowly in future.
Defining a problem as a data analyst
There are different methods to identify a root cause of a problem and we will have a closer look at 3 popular ones. Read the ease.io articles on the links below:

Create your own Pareto Chart using Microsoft Excel:
- Create a list of complaints and their count in Excel and select the data (Figure 1).
- On the Insert tab, in the Charts group, click the Histogram symbol. (Figure 2).
- Your Pareto chart will be shown. (Figure 3).
- Be sure to save your work for your portfolio of evidence.

The outcome is that the orange Pareto line shows that (789 + 621) / 1722 ≈ 80% of the complaints come from 2 out of 10 = 20% of the complaint types (Overpriced and Small portions). In other words: the Pareto principle applies. The Pareto chart has given us an insight into the root cause of the complaints.
