What is the Wide-band Delphi Estimating technique used for?

1. Determining project scopes

2. Estimating effort for user stories through team consensus

3. Gathering market research data

4. Planning team-building activities

The correct answer is: Estimating effort for user stories through team consensus

The Wide-band Delphi Estimating technique is specifically designed to improve estimation accuracy in project management, particularly within Agile methodologies. It involves a group of experts who provide their estimates for tasks or user stories independently and anonymously. After the initial round of estimates, the group discusses the outcomes, allowing participants to understand how their perspectives differ from others. This process is repeated several times, leading to convergence towards a consensus estimate based on collective insights and expertise. This method is particularly beneficial because it mitigates the effects of groupthink and encourages diverse viewpoints, making it more likely that the final estimate reflects a well-rounded understanding of the task at hand. It emphasizes collaboration and allows for informed discussions about uncertainties, assumptions, and risks associated with the estimates. The other options do not accurately capture the primary purpose of the Wide-band Delphi technique. While determining project scopes is an essential part of project management, it is not the main focus of this specific estimation technique. Gathering market research data and planning team-building activities refer to entirely different aspects of project management and team dynamics, rather than estimation methods.
