A final aspect of informed consent relates to how the data is used. Article 1.7 of the ACM [1] code states that information gathered for a specific purpose should not be used for another purpose without further informed consent. In an ESSE context for example, data collected to describe a software process should not be used to evaluate group members without their explicit informed consent to this additional use of the data. In general it is better to specify in the informed consent document all anticipated future uses of the data. If a researcher wishes to use data for a purpose that was not specified in the informed consent document, s/he must generally consult a review board to ascertain how to gain the informed consent for the current intended use. An exception of this rule exists for data sets in which all identifiers have been stripped and therefore the original contributors of the data
cannot be identified from the current data set [34].
