Take the following as truth: The first possibility is that the number of instances will need to be fairly large in order to achieve the generalizability wanted, and, as a consequence, skill will be needed to manage data collection with sufficient flexibility to obtain the insights case studies offer and sufficient structure to permit cross-site aggregation of findings.
Then the following statement: "There only needs to be a small number of instances for the generalizability wanted." is true, false, or inconclusive?
Answer: False
