In situations where unforeseen problems prevent the planned execution of a project, the project manager should focus on problem-solving and collaboration to keep the project on track. According to the PMBOK Guide, the project manager's responsibilities include engaging with stakeholders to meet project requirements and creating customer satisfaction1. The Professional in Business Analysis Reference Materials also emphasize the importance of collaboration and stakeholder engagement to address issues and find solutions2.
Therefore, helping the customer find an alternative location aligns with the project manager's role in facilitating project success and maintaining stakeholder satisfaction. References:

For a business-facing software rollout, the most effective way to transfer knowledge and enable adoption is structured end-user training (D). Training ensures finance users can perform real tasks (month-end close, reconciliations, report generation) confidently and correctly, reducing errors and resistance while accelerating realized benefits. Training can include role-based sessions, hands-on labs with realistic scenarios, job aids, and Q & A, which directly supports change management and operational readiness. A support portal (A) is valuable for ongoing help after go-live, but it typically complements training rather than replacing it-users need baseline competence first. A user handbook (B) provides reference guidance, yet many users do not learn complex workflows effectively from documents alone, especially under deadline pressure like month- end. "Project documents" (C) are usually technical or management artifacts and are not designed for operational knowledge transfer. End-user training best aligns with PMP objectives for stakeholder engagement, transition to operations, and benefits realization by ensuring the intended process improvements actually occur in day-to-day use.
