Which visualization techniques are commonly used in Celonis?

C is the appropriate choice because process maps and flow charts are fundamental visualization techniques used in Celonis to represent and analyze business processes. These techniques allow users to see the flow of activities within a process, identify bottlenecks, and understand how different elements interact with one another.

Process maps provide a visual representation of the various stages in a workflow, illustrating how data travels through the process and where delays or variations may occur. Flow charts complement this by detailing step-by-step actions, decision points, and the sequence of operations, which help in recognizing inefficiencies.

In contrast, infographics and pie charts (the first option) focus more on data presentation rather than the detailed exploration of processes. Email campaigns and surveys (the second option) are more about gathering feedback and insights from stakeholders rather than visualizing process performance. Spreadsheets and presentations (the fourth option) are effective for data management and sharing information, but they do not specialize in visualizing process flows in the way that process maps and flow charts do, making them less suitable for process mining tasks.
