A software costing method that uses a team of experts working both independently and together to combine different approaches and arrive at a collective judgment through consensus?

The described software costing method is known as the Delphi technique. It involves gathering a panel of experts who independently provide their estimates or opinions, which are then shared and discussed in a structured manner. Through multiple rounds of feedback and discussion, the experts refine their estimates, ultimately reaching a consensus on the software's cost. This approach leverages diverse perspectives and expertise to enhance the accuracy of cost predictions.
