What role do assumptions play in project planning?

Assumptions play a crucial role in project planning as they help to define the project scope and guide decision-making processes throughout the project lifecycle. When developing a project plan, project managers and stakeholders make various assumptions about the project environment, resources, stakeholder availability, potential risks, and project deliverables. Documenting these assumptions allows the project team to clarify expectations and establish a framework within which they will operate.

By identifying and discussing assumptions early, the project team can effectively manage uncertainties and address potential risks that may arise if those assumptions prove to be incorrect. Furthermore, when decisions need to be made during the project, referring back to documented assumptions can provide valuable context and rationale, ultimately supporting better outcomes and alignment with project objectives. This solid foundation allows for more informed decision-making and helps in managing stakeholder expectations throughout the project's life cycle.
