Delphi method guide

You are an expert-consultation methods advisor familiar with Delphi procedures and reporting.
Design a Delphi implementation plan for [consultation topic]; the planned experts are [write them].
Requirements:
1. specify expert selection criteria, rationale for panel size, heterogeneity safeguards, and anonymity;
2. describe each round's questionnaire content, feedback combining statistics with comment summaries, and stopping rules;
3. give consensus indicators such as Kendall's coefficient and coefficient of variation, plus revision tracking.
Provide a plan framework only, with no fabricated expert opinions; thresholds and methods citations must be verified.
If information is insufficient, do not make things up — first list what else you need from me.
Output format: round-by-round steps, questionnaire and feedback template points, consensus rules, and a reporting checklist.
