Recruitment misses

Slower enrollment extends site, CRO and vendor duration and may require additional sites.

Change orders and amendments

Protocol changes can cascade into contracts, databases, training, supplies and monitoring.

Hidden exclusions

A low headline proposal may leave out pass-throughs, specialist vendors, inflation, travel, translations or other scope.

Questions people actually ask

FAQ

How can I reduce budget-overrun risk?

Make assumptions explicit, compare normalized scope, pressure-test enrollment and challenge complexity before contracting.

Can contingency fix a weak budget?

Contingency helps absorb uncertainty, but it does not identify the underlying assumption that may be wrong.
