Dear Wahibha

Please find different with link to communication

Effective communication means that the information is provided in the right format, at the right time, to
the right audience, and with the right impact.

Efficient communication means providing only the information that is needed.

If you want an easier way to memorize the difference, remember this sentence: “Being effective is about doing the right things, while being efficient is about doing the things in the right manner.”

Thanks Kshitij
“Being effective is about doing the right things, while being efficient is about doing the things in the right manner.”
This statement make good sense ....

On Projects efficiency is like output matrices , like how many deliverable you produce in a given time , that is efficiency . While the effectiveness would be how useful thous deliverable were for the customer or end user.

Precision is a measure of exactness. For example, the magnitude for each increment on the measurement’s number line is the interval that determines the measurement’s precision—the greater the number of increments, the greater the precision.

Accuracy is an assessment of correctness. For example, if the measured value of an item is very close to the true value of the characteristic being measured, the measurement is more accurate.

An illustration of this concept is the comparison of archery targets. Arrows clustered tightly
in one area of the target, even if they are not clustered in the bull’s-eye, are considered to have high precision.

Targets where the arrows are more spread out but equidistant from the bull’s-eye are considered to have the same
degree of accuracy.

Targets where the arrows are both tightly grouped and within the bull’s-eye are considered to be both accurate and precise. Precise measurements are not necessarily accurate measurements, and accurate measurements are not necessarily precise measurements.
