Due to the improvement of technologies, the biggest problem for data today is not how to gather the data, but how to effectively use the huge amount of data you gathered and how to show it to decision-makers. That’s the reason why we need to have QA session for this class and enjoy “analyze!” several times a week！
This HBS article is about how P&G presents data to decision-makers. I know some of you guys have already or are trying to found a job related to data analysis in big organizations, and this is the article you do not want to miss.
This article gives an example of ”heatmap”(I do not know why there are some color mismatches in the example, but never mind), one display to show where P&G’s products stand in their respective markets. Simultaneously it shows all the markets in which P&G products compete and their relative share (red indicating low market share and green indicating high market share), and also puts in clear perspective the importance of growing the share of any one of those markets. It can save time for decision-makers to know what’s going on in different countries and help them to make the right decision.
In such a data abundant world, what data should really be used and how it should best be displayed are the key questions for a company, and for those who want to pursue his or her career in data analysis area. I hope this article can provide a little help. ：）
