Bullet Charts is a variation of the bar chart developed by Stephen Few.
They are emerging as a strong alternative to Gauge Charts. It is used for analyzing whether a parameter score is poor, average, good or excellent. One can use it for determine employee engagement score, actual vs target, HR audit score etc.
- 0 – 30% = Poor
- 31% -50% = Average
- 51%-70% = Good
- 71%-100% = Excellent
One must base the scales depending on requirement.
If you are measuring a performance score then a 75 % score is excellent. However if you measuring employee attrition then a score of 75% is very negative. Here your scales will be reversed where 0-30% will be a fair score. Therefore user must determine how the parameter would be measured.
Bullet charts in addition to the scales have an actual achievement and a target parameter associated with it.
However in our attrition chart we are using only the actual parameter to see in which scale our attrition percent lies.
