Yes. PCORI strives to adhere to the period of performance posted on PCORI website. If a delay in execution becomes inevitable during contract negotiations, PCORI will work with recipient institutions to adjust the period of performance and related milestones, if possible given the constraints.
Once a contract is executed, a period of performance may only be changed when a justifiable and written proposal is submitted to PCORI’s Program Officer, and approved in writing by PCORI’s Director of Contracts Management and Administration office, by way of written contract modification.
