Overview Consider the documentation and human resources pushing the study through its life cycle. Project managers need to monitor the completion status of the files. Statisticians and analysts have to identify data requirements and lay out "Dummy" displays. Programmers have to write the programs to create the data and reports using specifications that are often, to be kind, "Fluid." Creation of high-quality output requires coordination of effort and clear and immediate communication of results. Rho has migrated much of the requisite project management and data and display specifications to carefully designed and utilized metadata. By moving items that describe data sets and displays from documents and low-level programs into data sets, the authors have realized significant gains in productivity and quality of output.
