Research Handbook 4. Because the actual proposal development process can take days, weeks and even months, we recommend that the PI contact their OSP administrator very early in the proposal process, so the administrator can help facilitate the overall process. OSP, because of its responsibility for review and the volume of proposals, requires that when the proposal is ready for final review and signature, it is submitted to OSP three working days before it is due to the sponsor.
All federal agencies have plans in progress for full electronic submission of proposals .
Networks are frequently stressed during peak submissions times.
