In the transition from traditional data analysis methods to embracing data visualizations like Tableau dashboards, some individuals still find comfort in cross-referencing data with Excel. At Boulder Insight, we acknowledge this tendency and offer clients Quality Assurance (QA) sheets derived from our approach of constructing calculations within Tableau. By breaking down calculations into manageable components, users can validate data in a manner akin to Excel but within Tableau's interface. Looking forward, as AI and Machine Learning continue to advance, data visualization tools will become even more powerful, enhancing decision-making capabilities. However, we recognize the enduring importance of human validation instincts and strive to facilitate easy validation processes for our clients.
