On projects with a low complexity profile,

the process for evaluating risk is more formal with risk assessment meetings held during the life of the project to assess risks at different phases of the project an outside expert may be included in the risk assessment process and the risk assessment plan may take a more prominent role in the project execution plan the project management team may develop a list of items perceived to be higher risk and track them during project reviews

the project manager may informally track items that may be considered risk items

statistical models are sometimes used to evaluate risk because there are too many different possible combinations of risks to calculate them one at a time
