If you do something efficiently, it means you do it without waste -- of time, of money, of resources. Energy-efficient appliances are those fridges and washing machines that get the job done without using too much electricity. An efficient worker will have the report on the boss's desk by the deadline without having to stay late. If something is effective, it achieves achieves its goal. If a grammar explanation is effective, the student will understand. If negotiations in the Middle East are effective, there will be peace. In general I would say that people can be efficient, but not effective. Actions tend to be effective. People, actions and objects can be efficient. I would also say that something can be effective without being efficient: writing business letters by hand can be effective, but isn't efficient unless you use a computer or email.

Effective is mean you could reach the destiny Efessien is mean you could reach the destiny with the best way Like you want to kill a bird you can use bomb or gun Use bomb is to much Both of that is effective But use gun more efective and effecien

the best way I can answer this is in business terms: Effective can be viewed as how it be used to persuade or motivate (The the most effective way to motivate staff is by conducting ongoing personal development sit-down meetings) Efficient can be the rate of speed something can be done or repeated. (using speech-to-text software is more efficient than typing) hope this helps:)
