Which of the following tasks need to be completed during the planning stage of a project?

Understanding the project background is fundamental during the planning stage of any project. It sets the context for all subsequent decisions and actions. Knowing the project background involves gathering information about the project's objectives, stakeholders, constraints, and any previous work that may impact the current project. This background knowledge helps project managers and team members align their efforts with organizational goals and understand the needs and expectations of stakeholders.

A comprehensive understanding of the project background also aids in risk assessment and management, ensuring that the project can navigate challenges that may arise due to prior decisions or circumstances. This foundational knowledge underpins all other planning activities, making it essential to familiarize everyone involved with the project's scope and significance before moving on to specific tasks like technical design or resource planning.

The other tasks, while crucial, are typically addressed as the project progresses beyond the initial planning stage. For example, technical designs, network device models, requirements clarification, and IP address planning are all detailed elements that build upon an established understanding of the project's background.
