However, I believe in the measurement of activities that leads to a sale, much more than just looking at the sales figure alone, simply because to make a sale, there are many factors involved before the transaction is made.

It could be due to the emotional factors, or the level of professionalism involved, or simply because I was just a more convenient candidate. The opposite is also true, where a sale might not happen due to various reasons and it would be good if we can actually measure these failures if we had a clear measurements of our own activities, whereby we have a better control over.

On the other extreme, if sales is the only measurement (I know this is not what you meant, but just to illustrate the point), it's likely to lead to compromises on ethics and values which could be much more valuable in the long scheme of things.

In my opinion, the end should not justify the means.
