Successful projects begin with comprehensive preliminary studies and evaluation reports. The preliminary phase investigation should access the current systems and define any inadequacies or substandard components. Once the inadequacies are defined, DG staff can compare alternative solutions to resolve the deficiencies and fulfill the project objectives. Knowledge and actual experience with alternative systems is crucial for a meaningful comparison to be made. Comparisons without experience in the type of processes or systems being compared can be of limited use. Familiarity with funding sources and regulations is also crucial for the overall success of the project. Finally DG staff specialize in presenting complex technical issues at public informational meetings using understandable terms and audiovisual techniques.
