How you develop your skill at using a data visualization tool for business intelligence and problem solving/investigation. In part, this means picking an appropriate kind of visualization to really help find patterns in the data and present a convincing view of the issues.
Here is the situation:
Assume you are a marketing manager in this coffee house chain andyou have a sense that there are profitability issues in your products. You don't know exactly howto define the problem nor what factors contribute to the issues. But you want to explore thissituation by visualizing the data you've received from those kind folks in IT (your data mart in asingle Access table-well, not the normal BI data source, but it will do).So, call up the coffee chain data source and begin to explore. What products are underperforming? What correlates with profit? Are there issues with certain product lines, products,markets, pricing structures (margins), costs, ...? There are multiple answers. Treat this like a typical case study where you've been given data andyou need to find where the problems are.
- What I'd like to see in your report is an explanation ofwhat you discovered and enough screen shots from your analysis to show the logic of how youreached your conclusions and to convince me you found the problem.I suspect that with eachscreen shot you'd define what question you are asking, what you observe, and why you wentwhere you did next in your step-by-step problem exploration process.
- you have to have ajustification for where profitability issues are and their causes. You don't have to becomprehensive. Find two factors that identify where the issues are and what cause them.
- You have to generate several (roughly7) displays that show yourprogressive investigation, and these displays show different capabilities of Tableau (e.g., usingthe different shelves, filtering data, different styles of graphs -- Tableau does a lot of automaticgeneration of what it thinks is the right type of graph). In other words, treat this like a problemsolving, treasure hunt, or business case.
