"With the rapid pace of the project, you may not be able to get a formal written signoff from every stakeholder using a usual process of review, update, incorporate, distribute, and get signoff. Instead, you need to define the process. This could involve group presentations, verbal acceptance, implicit acceptance, or electronic signatures. Whatever is agreed to must be included in the updated project charter. Define who has acceptance authority. Keep it simple with a minimal number of approvals for a deliverable."
"Signoffs are not guaranteed, so you may need to negotiate what needs to be changed, updated, or postponed in order to continue the project. You also need a signoff from the project decision makers or their designate on the acceptance criteria before proceeding to the next subphase."
