Candidates should experiment with different chart types, layouts, and interactivity features, assessing how design decisions impact usability and insight generation. This practice ensures that candidates can create dashboards that are both functional and intuitive, meeting the needs of diverse business stakeholders.

Applying QlikView Skills in Real-World Scenarios

The QV12BA Exam emphasizes practical application of knowledge.
