Advantages
-Bring geographically dispersed panel experts together ( gaining input with minimal personal access)
-Anonymity and confidentiality of responses
-Limited time required for respondents to complete surveys
-Avoids direct confrontation of experts with one another ( no peer pressure, or extrinsic pressure)
-Structured/organized group communication process ( condense experts opinions into a few precise and clearly defined statements)
-Cost effective and flexible/adaptable, fast, versatile.
Disadvantages
-No guidelines for determining consensus, sample size and sampling techniques
-Requires time/participant commitment
-Requires skill in written communication
-Time delays between rounds in data collection process (multiple data collection, analysis , processing)
-Concerns about the reliability of the technique
-Drop-outs, response rates ( dependant upon a speedy response by busy experts)

Hi
Trevelyan et al. formulated guidelines for the Delphi method. They give a nice overview of some methodological issues in following paper:Article Delphi methodology in health research: How to do it?
It might be of interest to you.
Kind regards
