AskiaSurf allows you to manage multiple waves of research in continuous projects (called campaigns) in a fraction of the time. It's easy and fast to determine how the questions in a new wave match those already in the campaign. Once the wave has been added, the project is ready for analysis in AskiaAnalyse or AskiaVista.
AskiaSurf automatically determines which questions and responses in a new wave are equivalent to those already in the campaign. You can then check these matches, dealing with any differences quickly, or override matches in detail, on a case-by-case basis. Best of all, with AskiaSurf you only need to match any two questions or responses once; you do not have to perform this work again when you add subsequent waves, as matches are carried over from one wave to the next.
In short, AskiaSurf makes wave reconciliation as quick and painless as possible, automating much of the process, but provides you with the power to make detailed manual interventions if you wish.
