The interview approach of this process is what allows a large number of projects to be compared without surpassing financial and logistical limitations, but it also limits the type of data that can be collected. Although participants will be drawn from the same project whenever possible to allow for multiple perspectives and data triangulation, there will be no way to verify how closely the participants’ descriptions correspond to actual events. In addition, participants will be located through my professional network, which is biased toward grassroots, non-governmental, language-based work, so it is possible that the responses obtained will not be representative of the field as a whole. Another weakness is that in some cases, participants may be asked to recall events that occurred long ago, which may lead to overrepresentation of unusual or emotional occurrences and a neglect of the more mundane aspects of the project.
