A risk is a possible event or circumstance that can have negative influences on a project. Its influence can be on the schedule, the resources, the scope and/or the quality. When a risk escalates, it becomes a liability. A liability is a negative event or circumstance that is hindering the project.

The primary data needed to do risk management are the following:

  • ID: unique identifier for identification in other documents
  • description: what is the risk?
  • effect: what can happen if the risk becomes a liability?
  • precaution: what can prevent the risk from becoming a liability?
  • contigency: how to handle the liability?
  • risk status: status of the risk: new, ongoing, closed
  • risk escalation probability (P): what is the probability of the risk becoming a liability (rating from 0 to 1, for example)
  • schedule impact (S): what is the impact of the liability on the project schedule.

In addition, every risk can also have a number of action points associated with it. This is to ensure contingency when the risk becomes a liability.

From the information above and the cost accrual ratio (CAR), i.e., the total average cost per person per time unit, a project manager can calculate

  • cost impact (C = CAR * S): the cost associated with the risk if it arises.
  • schedule variance due to risk (Rs = P * S): sorting on this value puts the highest risks to the schedule first.
  • cost variance due to risk (Rc = P * C): sorting on this value puts the highest risks to the budget first.
