Managing such complex interactions requires, however, new decision-making and communication tools. The chapter discusses the effectiveness and efficiency of several such tools such as nominal group technique and Delphi surveys. None of these tools are perfect but they are capable of facilitating group input and multi-actor involvement.

The surveys attempt to define the ideal core at the level of concepfs rather than courses, whose names could be misleading. The results have been discussed with members of the bioengineering educational community, and detailed reports on both of these topics are forthcoming. Preliminary results of the work on current curriculum can be found in a proceedings paper [17], and the raw data from the first round of the Delphi Study are all posted on the VaNTH website (www.vanth. org/curriculum). Here we summarize some of the important points.

The process is continued until a consensus among the experts is reached. The process can take several rounds to reach consensus. In the past, Delphi process used to be very time-consuming and took several weeks. However, using email and online surveys, the Delphi process can be done in a matter of days.
