BIE product histograms
Using the values 1 through 5 as the range for each of Breadth, Impact and Ease, the product of the three yields values from 1 through 125. Out of curiosity, I determined the unique values (by spreadsheet enumeration) and made histograms of them.
Values
It turns out there are 30 unique values.
Value Frequency Percentile Value Frequency 1 1 * 1% 12 9 ********* 2 3 *** 3% 20 9 ********* 3 3 *** 6% 8 7 ******* 4 6 ****** 10% 4 6 ****** 5 3 *** 13% 6 6 ****** 6 6 ****** 18% 10 6 ****** 8 7 ******* 23% 15 6 ****** 9 3 *** 26% 16 6 ****** 10 6 ****** 30% 24 6 ****** 12 9 ********* 38% 30 6 ****** 15 6 ****** 42% 40 6 ****** 16 6 ****** 47% 60 6 ****** 18 3 *** 50% 2 3 *** 20 9 ********* 57% 3 3 *** 24 6 ****** 62% 5 3 *** 25 3 *** 64% 9 3 *** 27 1 * 65% 18 3 *** 30 6 ****** 70% 25 3 *** 32 3 *** 72% 32 3 *** 36 3 *** 74% 36 3 *** 40 6 ****** 79% 45 3 *** 45 3 *** 82% 48 3 *** 48 3 *** 84% 50 3 *** 50 3 *** 86% 75 3 *** 60 6 ****** 91% 80 3 *** 64 1 * 92% 100 3 *** 75 3 *** 94% 1 1 * 80 3 *** 97% 27 1 * 100 3 *** 99% 64 1 * 125 1 * 100% 125 1 *
The median value of the product is only 18, which may substantially skew the reader's perception of the product rankings. For example, 62 might seem like a "middling" value between 1 and 125, but it is actually in the 91st percentile of possible values.
Color schemes
Using the canonical source for decent color coding schemes, here are two suggested colorings by priority triple product:
lo | hi | stop-n-go | temperature |
---|---|---|---|
1 | 6 | #fc8d59 stop | #67a9cf cold |
8 | 16 | #fee08b careful | #d1e5f0 chilly |
18 | 30 | #ffffbf well | #f7f7f7 ok |
32 | 50 | #d9ef8b ok | #fddbc7 warm |
60 | 125 | #91cf60 GO! | #ef8a62 hot |
The stop-n-go is the center five values of "7-Class Diverging RYG". The temperature is the center five values of "7-Class Diverging RdBu".
BIE Interpretation
Code | Breadth | Impact | Ease |
---|---|---|---|
5 | Everyone | Critical -- Can't use the product | Trivial -- Edit and test |
4 | Most Users | Large | Easy -- Think, edit, and test |
3 | Many Users | Moderate -- Major annoyance | Moderate -- Substantial new code |
2 | Few Users | Minor -- Easy workaround | Hard -- Research and/or experiments |
1 | Only me | Hardly -- Barely notice | Impossible -- No idea how to do |
