You have accepted an audacious challenge and offer this initial public presentation with great clarity in an intuitively satisfying and persuasive way to novice and more experienced evaluators alike. Evaluation guides have, to date, tended to be, limited, fragmentary and partial within these constraints accomplished with varying success. The challenge that BetterEvaluation has sought for itself - and is demonstrably executing with informed confidence - is a far greater one than has previously ever been attempted. It is by the far the most comprehensive and will be of inestimable practical value and utility to the international evaluation community. You merit unreserved congratulations first on having conceived of such an enormous task, second on demonstrating the leadership to address it and finally on presenting its initial realization in such an accessible manner.
