Have you ever thought about the difference between effective and efficient?
Use effective when you want to say that something gives the result that was intended. Effective tells us whether something has been done, not how it was done. The focus is on the result.
Those pills are really effective – my headache disappeared in less than twenty minutes. The manager’s speech was short but remarkably effective.
Being effective can also mean officially start.
The new regulation is effective from 1 October.
Use efficient to say that somebody or something works well without wasting time, money or energy. Efficient tells us how something was achieved. The focus is on the process, on minimising cost or waste.
We are installing a much more efficient cooling system. She is a very efficient salesperson.
To sum up, effective is goal-oriented and focuses on the ability to produce a wanted result; efficient focuses on how little was wasted to produce the result. Or, to quote Peter Drucker, being effective means doing the right things, being efficient means doing things right.
An efficient company will do things at a lower cost (with higher profit), but it must also meet the customers’ requirements by being effective.
The corresponding nouns are effectiveness and efficiency.
If you have seven minutes to spare, here is a video explaining the difference between effective and efficient. And here you can read about affect and effect.
As a non-native writer of English you are naturally influenced by your own language and culture. When you write in English for an academic or scientific journal, you should bear in mind the Anglo-American style. It is especially important how you structure your text.
The text should have a clear structure with a linear presentation of the main idea and sub-ideas. Scientific journal articles are usually structured according to what is abbreviated as IMRAD, referring to Introduction, Material and Methods, Results and Discussion. To facilitate understanding, each paragraph deals with one issue, and a set of paragraphs form a logical unit.
Sentences, too, must be clearly structured. The subject comes before the verb, and adverbs and adverb phrases begin or end a sentence.
Writers from other cultures may be used to a different way of expanding on an idea; they may deviate from the topic, giving further examples and explanations, often in complicated sentences.
In some languages, adverb phrases can be inserted in the middle of a sentence, often breaking up verb forms or a verb and its object. This is not done in English, where the adverb phrase instead is put at the beginning or the end of the sentence.
Don’t write: The company has in Sweden 600 employees. Write instead: In Sweden the company has 600 employees. Or: The company has 600 employees in Sweden.
Don’t write: The technology is by some manufacturers expected to be dominant on the market within five years. Write instead: Some manufacturers expect the technology to be dominant on the market within five years. This example also shows that it is better to change passive voice to active.
