Coca Cola is a very successful company, with limited weaknesses. However they do have a variety of weaknesses that need to be addressed if they want to rise to the next level. Word of mouth is probably a strength and weakness of every company. While many people have good things to say, there are many individuals who are against Coca Cola as a company, and the products in which they produce.Word of mouth unfortunately is something that is very hard to control. While people will have their opinions, you have to try to sway their negative views. If bad comments and views are put out to people who have yet to try Coca Cola products, then that could produce a lost customer which shows why word of mouth is a weakness.
