“If the team decides that it is important that an idea be ranked as ‘extremely hard’ or ‘very high payoff’, you can make a note of that or place it along a quadrant accordingly, but try to encourage team members to think of the chart as only 4 choices. Ranking the ideas along a continuous scale is a waste of time since the relative ranking is not going to be recorded and analytical people tend to argue too much about where exactly along the scale an item belongs.” — Jon Wittwer

“Apple’s Xserve RAID allows you to choose which is more important to you–performance or integrity.

“Unfortunately, many default settings on data mining and statistical software automatically create decision trees or rules sets that are preprogrammed to distribute the cases evenly. This can be a huge problem when dealing with infrequent events or otherwise unequal distributions. Another way of stating this is that the program assumes that the prior probabilities or “priors” are 50:50, or some other evenly distributed ratio.” — Colleen McCue
