The HBR articles are OK, but their main value is as reading material for students. How many business people really care about a case study of the cell phone industry 10 years ago? This sort of thing has an increasingly short shelf life. And the case study approach to business school is becomong outdated because it teaches student to do business analysis on scraps of information.
It would be much more useful to have some of the classic business analysis scenarios presented as large data sets with the code for the analysis.
