23. Monthly Services Survey 23 Collection Scheme The MSS data collection according to the new framework of the conceptual, statistical design and sample (7.792 economic units), contemplates two slopes, that are: Interview method (entry data by the interviewer, into the Intranet System ). Collecting by Internet, (direct entry from the informant by Internet System ). In both cases, the information is delivered and valided by electronic means, by direct input data Internet/Intranet, as well as in a direct way by the informant in the Internet system.
