We need a common and objective framework to compare the various proposals In other task groups, a comparison criteria document is created to define simulations, tests, measurements and other comparison criteria These results are used to qualitatively compare various aspects of the proposals We need a similar document for TG6

Omeni, ToumazSlide 5 Conclusion We need a fair and objective way to compare the proposals A comparison criteria document is also useful to the proponents as it defines what simulations they need to run and what information they need to provide as part of their proposal A comparison criteria document is a win-win for the group
