“We chose Welphi for our Delphi study because it offers some features that standard online survey softwares do not, such as an informed consent page and separate storage of person-identifying information and responses. Welphi is the only option we found that enabled us to send reminders and invitation to next rounds to participants without learning their responses to previous rounds – an essential feature of Delphi methodology. Another advantage is that as a small firm, support from Welphi is personal and fast.”
