I agreed with Girotra andNeressine’s opinion. An appropriate business strategy and audit the strategy constantly will help a company gets more profit and success. Today, e-business becomes more and more popular. However, the market is almost perfectly competitive and has a strong buyer power. Therefore, if a company does not build its point of difference and has some competitive advantages, the company will hardly survive. Amazon does a good job in this. Recently, it begins to provide Sunday deliveries service in several large cities in the USA, such as New York, and LA. This strategy helps Amazon successfully attach customers to purchase on Amazon.

Another famous example is Alibaba Corporation. It is a famous Chinese e-business company. It was founded in 1999, and today it is one of the biggest e-business companies in the world. At first, Alibaba just provided an online market for business-to- business service. Later as the company grew, it began to provide Consumer-to-Consumer, and Business-to-Consumers service. In 2012, the corporation divided their business into three companies (Tmall, Taobao, etao). The goal was to provide a better service to different types of customers. Tmall is better on Business-to-Consumer service, and Taobao is better on Consumer-to-Consumer service. By applying appropriate business strategies in different time, Alibaba becomes really successful.
