If, however, the evaluation question requires GAO to report on how satisfactory progress is or the reasons for problems in implementation, the more staff who can be on site over time, with the ricHe'st or thickest base for examining the situation as the many people involved see it, the sounder our causal conclusions and subsequent recommendations will be.
If the GAO has to report on the progress, the recommendations will be better because they will have more input from experts.
