What causes E-Commerce to fail

Like any new business strategy, implementing e-commerce also has its risk and there are a number of things that could go wrong, for example:

• Poorly designed web site
  Website which poorly design may cause user to be lost in their website and may cause them to eventually stop going there
  

• Misunderstanding customer needs
  Some organization may concentrate more on developing the website and neglect their customers. A website which does not work for them will cause them to move on to other website where the internet is just a click away.
  

• Insufficient trained staff
  No matter how good the website is if there are insufficient staff there will be no one there to maintain the website
  

• Focusing on the technology rather than the content
  Some developer try to implement Flash, Java, Shockwave and others which may increase the load time of the customer when browsing the website. It may cause a problem to customer who is connection using dail-up connection.
