Introduction The question that was troubling me for some time has been answered: “Can anybody make a Blaise survey without writing any Blaise code?” This all started with one project that became larger during time. The Welfare Benchmark of the Netherlands is a project for the Dutch Municipalities to learn and improve their method of applying Municipal welfare programs. The Welfare Benchmark collects data from the Dutch Municipalities using Blaise programs to form a unique central database. The big challenge in 2003 is that this National project has expended itself to not just 1 Benchmark but to a total of 5 Benchmarks. With only 2 Blaise programmers this was an unthinkable task. How could we use Blaise at its maximum potential? The answer came with the development of the Blaise Survey Generator, the Excel Survey Generator, and the Blaise SPSS Generator: easy survey making code for non Blaise-users, namely our researchers. It is the development and implementation of these Generators with the use of Blaise and BCP program and all the procedures of creating a Survey and Survey- results that this paper addresses. We were confronted with the following (technical) aspects: easy Blaise use for the Researchers, easy survey making and remaking for the Researchers, easy Survey-question ordering, easy Survey-table making, easy Survey-routing, and easy Survey-results for the programmers. Finally, this paper will address which important elements made these Benchmarks so successful and the working relationship with the Central Bureau of Statistics Netherlands, which contributed to its successful implementation. 2. The target group The VNG is the national organization for Dutch municipalities. It contains the nonprofit agency StimulansZ that advises all the municipalities about handling the welfare grants from the government for its welfare recipients. With the help of SGBO (research and consultancy department of the Dutch Local Government Association,VNG) and CentERdata (research expert center of the University of Tilburg) it has made a Blaise Internet program for the Dutch municipalities. Dutch municipalities send their government official, who is responsible for the Welfare program, to a major meeting of StimulansZ. In large municipalities, this person will delegate the Benchmark project to other government officials but in regular municipalities they would have to enter their data through the use of Internet. Through this data, StimulansZ will measure long-term progress in achieving the Government strategic plan goals: municipal cooperation, collaboration, and a result-driven approach to problem solving. The benchmark results from the municipalities will be compared and the results will show how 7 compatible municipalities as a whole are doing, and by performance measurement systems, which seek to measure how a given municipality is performing. This was the first year that only the Internet could be used for data-entry. A lot of data has to be entered by the Dutch municipality that it becomes important for the government official to see an overview of al the entered data. Also with the use consistency tables that show a subtraction, addition of certain questions are necessary for accurate data entry. Otherwise the Welfare Benchmark would be a total failure. This year the government official could easily move from one chapter to another and from one question to another through the whole questionnaire. 3. Easy Blaise use for the Researchers: “Blaise Survey Generator” Imagine a very busy period and that there is a change in the research staff. A new researcher has just been introduced to your colleagues and you want him to write a data-entry program in Blaise immediately. At that moment you would give him the use of the ‘Blaise Survey Generator’. The new researcher is an expert in a certain research area and can therefore formulate
