Successful long-running surveys may repeat year after year, asking the same questions in the same way and creating useful trend lines. Change comes slowly but inevitably if these surveys hope to remain vital and relevant. The Medical Expenditure Panel Survey in the US offers a case study in managing such change, transforming to commercial off-the-shelf data collection software (Blaise) while preserving the structure, format, and delivery schedule for all public use files.
Overlap in design, programming, and testing phases must be carefully managed. Moreover, balancing resources between the new development in parallel with the ongoing demands of field and processing operations in the old system, with no accommodations in the schedule or loss of timeliness for data users, is a major management challenge. After launching the new software in the field, numerous quality metrics (derived from both data and paradata) are monitored to distinguish changes in the trend lines from changes (errors or error reduction) that may result from the transformation itself.
