A project manager is performing planning tasks for a complex project at a small company. Which of the following items would be of GREATEST importance during planning?

Defining the project objectives, scope, and success criteria is foundational during the planning phase because these elements establish what the project aims to achieve, its boundaries, and how its successful completion will be measured, guiding all subsequent activities. Without these, the project lacks clear direction and a basis for decision-making.

Assessing resources for operational support is important for sustainment, but it is a later-stage planning or transition consideration, not the greatest importance for initial project definition.

Providing updates and status reports is part of monitoring and controlling, which occurs throughout the project lifecycle, not the greatest importance for initial planning.

Developing a records management plan and reviewing artifacts are important for project administration and knowledge management, but less critical than defining the core purpose and boundaries of the project itself.
