im doing an assignment on effectiveness and efficiency in a business, especially in management, and we have to use argue which is better in an essay format. we also have to use real life examples of business to support our arguments, so can anyone give me a link to an article or something that has a story of a business's performance relating to this topic?? please help!
You could use an example of an advertising campaign. A company could spends millions of dollars on commercials and billboards to get a product out there. That example would be effective, but not efficient. That same company could make a silly viral video and "leak" it for free on the internet or any number of guerilla marketing tactics. That would be efficient, but may not be totally effective.

In management it could be the difference between fixing a machine or replacing it. Good luck!
