In risk classification, what do 'project risks' primarily affect?

Project risks primarily affect the schedule and resources of a project. This is because these risks pertain to factors that can impede the timely delivery of project milestones and the optimal use of resources such as personnel, equipment, and finances. When project risks materialize, they can lead to delays, increased costs, and resource reallocation, ultimately impacting the project's timeline and the efficiency of resource utilization.

By identifying and managing project risks effectively, teams can implement strategies to mitigate these impacts, ensuring that the project remains on track and within budget. In this context, understanding the relationship between project risks and their effects on schedule and resources is essential for successful project management in software engineering.

The other aspects mentioned, such as resource availability, market trends, and customer satisfaction, while important, do not encompass the direct relationship that project risks have with the schedule and resources during the lifecycle of a project.
