Final answer:
Time risks, budget risks, and scope risks are the common risks in project management, affecting the project's timeline, budget, and scope respectively.
Step-by-step explanation:
The most common types of risk that can impact projects are time risks, budget risks, and scope risks. Time risks involve the potential for a project to overrun the expected timeline. Budget risks are concerned with the potential for the project to exceed its financial resources.
