This presentation discusses Microsoft Corporation and the Boston Consulting Group (BCG) matrix approach. It provides background on Microsoft's founding in 1975. It then analyzes different Microsoft operating systems according to the BCG matrix categories: Windows 10 is a cash cow; Windows 7 is also a cash cow; Windows Phone is a question mark with low market share and growth; Windows Vista is a dog with low market share. Finally, it recommends post-analysis strategies for each category, such as increasing investment in Windows Phone to make it a star, and harvesting Windows 10 to maximize profits.
