  6. MAJOR OUTCOMES • STANDARD FOR INDICES EXIST IF INDICES ARE SATISFACTORILY COPED WITH BY VALIDATED MODELS (NO SHORT-TERM VARIATIONS ARE WELL REPRODUCED) • NO STANDARDS ARE SET FOR PREDICTION METHODS AS THEY ARE CONSIDERED NOT MATURE YET • NEW INDICES SHOULD BE ADOPTED WITH CAUTION TO MINIMIZE THE TOTAL AMOUNT • INDICES TUNED ACCORDING TO THE USERS’ NEEDS ARE OFTEN UNAVAILABLE 5th ESWW, 20 November 2008, Bruxelles
