Wideband delphi
open-in-new
<p>The Wideband Delphi estimation method is a consensus-based technique for estimating effort. It derives from the <a href="/facts/Delphi_method/KtWtgEVn">Delphi method</a> which was developed in the 1950-1960s at the <a href="/facts/RAND_Corporation/zArfRxf9">RAND Corporation</a> as a forecasting tool. It has since been adapted across many industries to estimate many kinds of tasks, ranging from statistical data collection results to sales and marketing forecasts. According to the <a href="/facts/Project_Management_Institute/8AygTItl">Project Management Institute</a>, Wideband Delphi is an "estimating method in which subject matter experts go through multiple rounds of producing estimates individually, with a team discussion after each round, until a consensus is achieved." </p>
