Structure your trial budget by development stage, site, and enrollment driver. Cost assumptions connect to the inputs that drive them, so the model stays current as the trial progresses.
When enrollment timelines shift or a site activates later than planned, the forecast updates at the driver level rather than requiring a manual rebuild. Finance always has a current cost view.
Compare actual spend to budget at the trial level as costs come in. Variances are visible by stage and site, not as a single total program number.
Every active trial lives in the same system. Finance can see total program spend and individual trial performance from the same source without consolidating separate files.
