Before commencing with the development of a measuring process, the deployment strategy must be clearly defined. There is a great difference whether a process is to be used only by its developer, or by people not able to fully evaluate the process. In the latter case precautions must be taken to eliminate faulty application. This applies especially when the measurements are utilized to judge the safety of a building. Well post-processed measurements, desirable in themselves, can easily mislead to use them uncritically.
Similar effects are familiar to structural engineers and the users of finite element programs.
One measurement is no measurement. This applies not only to the yard- stick. Nobody should be carried away to make a decision on the basis of too little data, even when urged by the client to do so and the data is in line with one's own concept. One wrong result can bring an entire testing method into discredit. Today's possibilities for data processing, visualization and data transfer should be utilized systematically, above all from the viewpoint of streamlined documentation and filing.
