Answer: The most carefully planned project can become trouble. No matter how well it's planned, projects can always encounter unexpected problems. Many get sick or quit, resources that were depending on turn out to be unavailable, even the weather can throw you for a loop. A risk planning can be used to identify potential problems that could cause trouble for the project, analyze how likely they are to occur, take action to prevent the risk, and minimize the ones that can’t. A risk is an uncertain event or condition that might affect a project.
