Professor use a lot of examples to instruct the relationship between information technology and people. As we know, companies use information technology to increase their profits. The example of Bestbuy attracts me a lot. As we can see, people always go to Bestbuy to try the products and purchased the item on Amazon.com as Amazon offers a cheaper price than Bestbuy. Then we talk about the three applications of IT, they are supply chain management(SCM), customer relationship management(CRM) and enterprise resource planning(ERP). And the five forces(entrants, competitors, substitution, suppliers, buyers) are important for a company. We have also learned the generic strategy in the class, Companies should choose a strategy to be mainly use when they enter a new market. Also, we have learned the value system and value chain.
