However, speaking to many of the BAs in my network, facilitation is the one area that they feel that they can do more. I guess, one of the difficulties with facilitation is that you don’t always end up with a tangible outcome. This then makes it harder to determine the value in what you have achieved.

I recently took a last-minute trip from San Francisco to India. The best fare in economy I could find was on a sixteen-hour Air India flight, direct to New Delhi. I figured I’d get a lot of work done on the flight and, if not, at least I could catch-up on movie watching. Turns out I was zero for two on this as my in-seat entertainment center didn’t work and I couldn’t get much of my work done either – I guess that means I was two for two on being surprised.

In this article, we will discuss the KNN Classification method of analysis. What is the KNN Classification Algorithm? The KNN (K Nearest Neighbors) algorithm analyzes all available data points and classifies this data, then classifies new cases based on these established categories. It is useful for recognizing patterns and for estimating. Let’s say we want to determine the likelihood of loan default based on two predictors (age and loan type), with ‘default’ being the target.
