Backfill Techniques Techniques used in cumulative case studies to collect information needed if the study is to be usable for aggregation; these techniques include, for example, obtaining missing information from the authors on how instances studied were identified and on the bases for instance selection.
Backfill techniques can be used to gather information on a case study so that it can be analysed in conjunction with other studies.
Case studies performed by different researches using different techniques cannot be compared or combined to reach useful conclusions.
