Wideband Delphi
Wideband Delphi is a structured, consensus-based estimation technique used in software development and project management to forecast effort, duration, or costs. It involves a group of experts anonymously providing estimates, discussing them in facilitated sessions, and iterating until convergence is reached. This method aims to reduce bias and improve accuracy by leveraging collective expertise through a systematic process.
Developers should use Wideband Delphi when planning complex projects with high uncertainty, such as new product development or large-scale system overhauls, to generate reliable estimates. It is particularly valuable in agile or traditional environments where accurate forecasting is critical for resource allocation and scheduling, as it mitigates individual biases and fosters team alignment. This technique helps prevent underestimation and scope creep by incorporating diverse perspectives.
