A technique used to estimate cost or duration by applying an average of optimistic,pessimistic, and most likely estimates when there is uncertainty with the individual activity estimates.Threshold. A cost, time, quality, technical, or resource value used as a parameter, and which may be included inproduct specifications. Crossing the threshold should trigger some action, such as generating an exception report.Time and Material Contract (T&M). A type of contract that is a hybrid contractual arrangement containing aspectsof both cost-reimbursable and fixed-price contracts. Time and material contracts resemble cost-reimbursable typearrangements in that they have no definitive end, because the full value of the arrangement is not defined at thetime of the award. Thus, time and material contracts can grow in contract value as if they were cost-reimbursabletypearrangements. Conversely, time and material arrangements can also resemble fixed-price arrangements.
