Relative Improvement Target target improvement value = baseline + (space improvement X relative improvement target)
for example:
baseline = 95%if relative improvement target is 10%:target improvement value = 95% + (1-95%)x10% = 95% + 0.5% = 95.5 %
baseline = 95%if relative improvement target is 15%:target improvement value = 95% + (1-95%)x15% = 95% + 0.75% = 95.75 %
baseline = 80%if relative improvement target is 40%:target improvement value = 80% + (1-80%)x40% = 80% + 8% = 88 %
for KPI which is the smaller the better:baseline = 2%if relative improvement target is 20%:target improvement value = 2% - (2% x 20%) = 2% - 0.4% = 1.6%
