Which product subcategory is the most unprofitable?

Again: which product subcategory is the most unprofitable? In this case, as humans, we effortlessly know that red means “pay attention” and in this data set, our eyes – completely subconsciously – are drawn to the red numbers. We’re able to perform visual analysis on this data set in a matter of milliseconds to hone in on the 5 rows with unprofitable customer segments. The amount of data we’re processing is much smaller and further analysis is easier. But we’re still comparing numbers…

Now … which product subcategory is the most unprofitable Now … which product subcategory is the most unprofitable? You can instantaneously see that Tables for the Home Office customer segment are the least profitable. In this instance, there are visual analysis cues that supported human’s nature perception triggers – in this case, both color and size comparison. While the previous data set helped us hone in on the important numbers through color, in this case, we aren’t being asked to do any number comparisons – and remember, numbers are actually very complex and largely theoretical, in this instance we are able to visually perceive insights without having to do any numerical comparison or in-depth processing. The comparisons we are doing are around the relative length of the bars in the chart, the color differences. And as with the math problem, when we’re given the right tools, our ability to get to the “answer” in this case –the analysis – is much, much faster. In fact, I’m sure for most of you, the answer to which product category is the most unprofitable you’ve already moved on to thoughts like, wow, office machines for the corporate segment are doing really well! Or, technology is by far our most profitable product category regardless of customer segment.
