Final answer:
Lack of a PMO can lead to unclear timelines, overburdened staff without dedicated project support, and no systems for long-term evaluations, affecting the organization's effectiveness and strategic decision-making.
Step-by-step explanation:
If an organization does not have a Project Management Office (PMO), various challenges could arise. The absence of a PMO may lead to a lack of clear timelines for planning and implementation processes. It could also result in insufficient support for staff who need to balance their participation in new programs with their regular, funded project duties. This scenario might become particularly stressful in situations where funding is uncertain, such as when political changes threaten the continuation of certain programs. Without a PMO, the organization might also lack the necessary systems for conducting long-term follow-up evaluations. This means that the organization may face difficulties in assessing the effectiveness and impact of its projects over time, potentially hindering continuous improvement and strategic decision-making.
