Generating Percentage S-curvesPercentage S-curves may be generated by dividing the Year To Date (YTD) daily totals for each Day for each S‑curve (Baseline, Actual, Target) by either the total Baseline Man Hours (Baseline = 100%) or Target Man Hours (Target = 100%). Generating Percentage S-curves (Baseline = 100%)To generate Percentage S-curves with the Baseline = 100%, divide the Year To Date (YTD) daily totals for each S‑curve by the Baseline total Man Hours for each Day of the Project. - Baseline YTD % = Baseline YTD Total / Baseline Total Man Hours x 100%
- Actual YTD % = Actual YTD Total / Baseline Total Man Hours x 100%
- Target YTD % = Target YTD Total / Baseline Total Man Hours x 100%
The calculations for each S-curve are shown below.
