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%:
