The project manager should contact the project management office (PMO) for assistance after learning that a
similarly time-consuming project was executed previously in the organization. A PMO is a department or
group within an organization that provides centralized guidance, governance, standards, best practices,
resources, and oversight for project management activities. A PMO can help the project manager by providing
access to historical data, lessons learned, templates, tools, methodologies, and expertise from previous projects
that can be useful for planning and executing the current project.
